The engine cover, or valve cover, cylinder head cover, the cover is the engine.This is my graduation project... The NASTRAN is used, but the rest of the software is basically the same.Hope to have experienced master Zhidianmijin ah.At present, only 12 order free modal analysis is performed. The final is to do static strength, sealing. The details of the process are not clear. For example, how does the bolt hole bind? Does it hold all the points on the inside surface? What about the boundary conditions and loading? It has more than ten bolt holes, one ring gasket, and 120 0.7bar pressure inside. The material is engineering plastics.Or some people know the whole process from modeling to the results of the general steps to say, you can, thank you first. OK, add more. StopFrequency response and transient response are currently being done
What a big question you asked! I'll tell you a little about it. I hope it will help you.Let's first talk about frequency response analysis!1. study the specialized finite element mesh division soft (HyperMesh)If you have plenty of time, first learn about the finite element mesh, like Hypermesh. The mesh is pretty nice. And you'll probably use it later on,.2. establish the calculation modelGroup the mesh models into Patran, and then combine them with paste and other functions. As for the bolt hole, you can fix the inner surface. If someone asks you for a reason, you can say that the result is conservative, and that's how it works in Engineering3. detailed steps, you can find reference books.I haven't done it myself for tightness. I'm not sure about my point of view. First of all, the problem is thermal gas solid coupling. Ha ha, seems very complicated. I don't know. I understand, right?Suggest you change ABAQUS software, try it. I'm not sure. There are plenty of examples in each software that you can take a look at. The ABAQUS help file has examples of thermal coupling and fluid solid coupling. You combine these two examples to see. What might be like?
You have a lot of problems in this, and other people to advise you, it is also quite troublesome ah. I suggest that I try my best, try some specific questions and ask questions, so it will be better!
Such a professional problem, or experts answer better.
