The end of the year, too many projects, late reply, please forgive me.

Let me talk about your mentality first.

As you may have seen, I was just scolded by an unworthy seeker the other day, and the reason is also because of my mentality. I'm asking you this question because I think there are some things that need to be corrected in your present state. Your mentality can't be said to be bad, but what my friend said earlier is still reasonable and a bit empty. In the mechanical industry, you must keep your feet on the ground. But your mentality also has a good place, that is, after knowing your own strength, you can communicate with it with a higher attitude in the process of job hunting and interpersonal communication, which is virtually your winning weight.

So my advice to you is to learn to be Kong Ming. A solid foundation and broad horizons become proud capital for yourself, and a convergent attitude and gentle communication style become your psychological advantages over others.

Therefore, I hope you have a correct attitude, be practical and converge.

Let's analyze the two occupations you mentioned:

You know the problem of CAE very well yourself. Like other mechanical majors, CAE is really extensive and profound, and it is difficult to engage in it without a strong foundation in engineering mathematics and engineering mechanics. I'm afraid you don't know that in the early years, we were still dividing each grid manually, and even built the first operation model with paper and pen. But today, with the powerful function of ansys, what are we thinking when we look back at the operation model we built on paper with determinant and finite element? i agree with you on this point. Although CAE is powerful, it is still only an aid in the end, and these things that we felt the most headache before have now been basically completed by computers. At most, we are just thinking about how to divide the grid more reasonably. Of course, CAE also includes many other contents, not just finite element analysis. I just want to say that waiting for the last report of the computer all day is not what we want to do.

Wei Riguang said it very well. How to make CAE a compass for product improvement and optimization is the essence of CAE. If you can do this, this career is still very interesting. And as I mentioned before, the analysis report of CAE is likely to have the power of life and death for a project, even above the development, which is also the advantage of this profession.

I don't know how much you know about sports Please refer to my following post:

/question/ 1249 123 12 . html

So I think what you said about PE is not quite the same as what I understood. Because I also know that some companies will also be called design and development PE, but that is a minority after all, and I personally think it is unreasonable.

Because of our different definitions, several friends asked two questions about career development at the same time, and I will answer them all here.

Let me briefly talk about my personal thoughts on the two routes:

1.CAE->； R & ampD

This is relatively easy, because as I mentioned before, generally speaking, the development department is already the highest-level department in the company, and the general CAE is also located in the development department. From the nature of work, only CAE can surpass development in technology, so it is not a big problem to change from high to low. Everyone agrees on the problem of software. What we can master in a few days is beyond our discussion. There is no software, even a free hand, which is one of the basic qualities of development engineers. Then what is the biggest difference between R & ampD designers and ordinary mechanical engineers? Mechanical engineers, to a large extent, are solving problems; Mechanical designers create problems while solving problems, and solve problems while creating problems. ...

In the process of product design, in order to meet the needs of customers, we will bring many problems in the process of completing various functions. Let me give you a simple example:

The customer specified that the height of a box was 100, and we did it. Then CAE analysis said that the strength of the box was not good. then what

R & ampd will say to add stiffeners and then increase the height of the box. What should I do if the customer disagrees?

Only by changing the internal design and compressing the space; So what new problems will be brought about by compressing space? Chaos in layout, interference of parts and unreasonable processing. ...

When we solve all these problems, who knows what new problems will emerge?

This is the biggest headache for mechanical designers, and no design is perfect.

An experienced designer just says that he can foresee the possible side effects of a design and minimize them at the same time; And a good mechanical engineer is to solve those unreasonable side effects in a reasonable way in the most reasonable design that the designer thinks without changing the design; And a good CAE engineer will provide relatively reasonable solutions and suggestions for mechanical designers and engineers.

So CAE went to R&; When the direction of D deviates, the advantage is huge, but what is lacking is practical application. Mechanical design is comprehensive because in the process of creating and solving problems, almost all kinds of problems in the field of mechanical industry will be involved. These are all things that computers can't tell you, but you need to learn by yourself. I believe you will never finish learning.

From your description, it seems that you know something about conventional processing technology, so you don't need to go to the front line to study. On the second day, I suggested:

A. Go to industrial exhibitions more often.

When designing products, we tend to be thinking-oriented, so we often collect your opinions through peer review or brainstorming. The reason for this problem is that our horizons are not broad enough. If we don't know how to start when facing a problem, there is no possibility of creating a problem, let alone completing the design of a new product.

B. Do something by yourself.

The designer's hands are scarred. We are mice ourselves, and every new product is made by ourselves. Although each product work instruction is written by a mechanical engineer, it is reviewed by a mechanical designer. How to use each step reasonably, even how to protect the operator, is the responsibility of the mechanical designer. I hope you understand that designers not only design a product for users, but also design it for producers. Production line workers are also our customers, and we don't just want to satisfy every customer.

C. dismantle competitors' products by yourself.

Remember, you are not the smartest or the best. What you can think of, others will certainly think of, on the contrary, what others think of, you may not think of. Until today, when I often dismantle my competitors' products, I will still sigh that there is a set, which is unique and innovative. This is all we have to learn.

D. understand quality control and product process.

The working communication level of CAE is too narrow and the corresponding window is very small. The product design end needs to face the departments of market, sales, operation, procurement, production planning, engineering and logistics, and needs strong development process to support it. And there is a complete process to control the product from the initial stage of development to the end. If someone doesn't do it, it will not only cause problems, but also lead to many out-of-control scenes such as customer complaints, which can't be explained clearly in a few words. I believe you will have an experience after learning the relevant content.

2.CAE->； PE

To tell the truth, the work content of PE is far from CAE. See my post above for specific responsibilities.

Converting CAE directly into PE does not have many technical advantages, so it basically belongs to learning from scratch.

The technical content of PE is not high and its knowledge is not so wide, but the work content of PE is very interesting. It is appropriate to describe PE as the matrix of products.

When the development department completes a design, the first department to be notified is the engineering department/product department, and PE is the object of release. Then the establishment of engineering BOM, process documents, manufacturing manuals, and many things necessary for product production must be prepared or contacted by PE.

PE is often doing paperwork, and it takes a lot of energy to maintain the product database system. This housekeeper is not good, and she has the most contact with various departments and is also the most vulnerable department. There are a lot of people chasing after her ass all day, and how to deal with interpersonal relationships reasonably is also a big problem.

But good PE is also very strong, mainly in the following aspects:

A. I am familiar with the details of almost all products of the company. After a long time, I can almost become an expert in this product direction.

B understand the whole process of the company's product life cycle from development to production to upgrade.

C be proficient in all production-related processes and operation modes of the company.

D. Strong ability to deal with various conflicts.

In other words, if you choose someone directly from within the company to start your own company, then the best candidate is PE, because PE can do everything except product design. Although development designers also know this, but the degree of understanding can not be compared with PE. As long as PE finds a reasonable home (design department) and a reasonable home (sales department), then he can start his own company.

I'm afraid it's difficult to learn the related work content of sports in advance. Generally, only when you really take up this post can you have a deep understanding of these work contents, so if you want to engage in this profession, you must calm down and suffer.

I may have worked too much overtime these days, and I am a little confused. Let's call it a day, thank you.
