感谢回复,你说的很对,CAE在我公司目前就属于花瓶状态,水平很初级,试验也做的很少
老总很希望我们CAE ...
I can see why CAE department is not respected in your company.
You guys really have no clue about how CAE serves.
You said you guys are validating products with CAE, but does not have ability to propose optimizations.
Comparing two or more designs is the easiest job in CAE.
With all parameters stays the same, you can even tell the design guys by how much percentage improvement with the new design.
Except for super complex system, optimizing a structure is most time just common sense thing, not a lot of mechanical expertise involved, as I can assert.
And when you do have no clue on how to optimize, Optistruct is a good tool.
While, at the other hand, validating a design is the most difficult part of CAE.
You have to have precisely accurate parameters, material data, various coefficient, and of course the criteria.
A company should have run numerous test and correlation with CAE to get correct parameters and criteria.
There is only one reason for CAE department being neglected: cannot deliver accurate result.
When you say, you guys cannot recommend optimization proposals but validating products, oh hell no, if I were the design guys, how can I trust your validation is correct?!
