胀缩式卷筒是双卷筒卷取机的关键零部件,在卷取过程中要承受较大的径向压力,设计中通常会对其关键部件进行强度和刚度的校核。根据生产要求的不同,设计时选取的卷筒直径、长度等参数也会不同,每一个参数的改变,都需要重新进行强度和刚度的校核,过程非常繁琐。采用C++和PCL编程语言,并结合Inventor三维设计软件和MSC.Patran有限元软件,实现了一种快速校核强度和刚度的方法,简化了校核分析流程,缩短了设计周期,本文称之为参数化有限元分析。
The swell-and-shrink reel is a key part of a dual-reel coiler and has to be subjected to a large radial pressure during the coiling process. The strength and stiffness of its key components are often checked in the design. According to different production requirements, the design parameters such as drum diameter, length and so on will be different. For each parameter change, the need to re-check the strength and stiffness, the process is very cumbersome. Using C ++ and PCL programming languages, combined with Inventor 3D design software and MSC.Patran finite element software to achieve a rapid verification of strength and stiffness methods to simplify the check analysis process and shorten the design cycle, this article is called Parametric Finite Element Analysis.
