Finite Element Modeling and Modal Analysis on Suspension Equipment of Rice Rope Direct Seeding Machine

摘要

Analytical method and software technology of finite element plays a very important role in mechanical structural analysis. Suspension failure is one of important factors affecting the Rice Rope Direct Seeding Machine in life. In this paper, three kinds of structure of virtual model of the suspension equipment is set up with the assistance of UGNX three-dimensional software, on SOLID element type as basic type by NX Nastran Modules the finite element analysis model is also set up. The suspension equipment modal analysis in this work supply important modal parameter for the response analysis and assist to locate the weak links of the suspension equipment. The third option proposed in this work is the best option, which provide an effective way for the future structure of agricultural products design and development.
