Finite element analysis of 3D modeling parameters of flexible wheel teeth. The pre-processing finite element method is an effective tool for studying nonlinear elastic deformation. Ansys is used to simulate the assembly of the wave generator and the flexible wheel, and the state diagram of the engagement between the flexible wheel and the rigid wheel after the simulated deformation is given. In the Ansys numerical calculation, the material has a Poisson's ratio of 0.3 and an elastic modulus of 1.97*e10Pa. The SOLID186 unit is used to divide the soft teeth, the ring gear and the cup in four steps to obtain a better network. grid. In this paper, the static contact between the wave generator and the flex wheel is simulated. The rigid tooth profile is used as the meshing reference. It is not necessary to obtain a relatively uniform mesh, so it can be freely divided.
In the contact simulation between the soft wheel and the wave generator, the outer diameter of the deformed wave generator is slightly larger than the inner diameter of the flexible wheel. In order to simulate the assembly process, the electromagnetic brake installs the wave generator into the prestressed state generated by the flexible wheel, introducing contact. Boundary constraint; the inner cylinder surface of the flexible wheel and the outer cylinder surface of the wave generator are defined as face-to-surface contact, wherein the inner cylinder surface of the flexible wheel is defined as the contact surface, and the outer cylinder surface of the wave generator is defined as the target surface, and the friction coefficient And the contact stiffness is taken as 0.1. Fix the freedom in all directions of the inner ring surface of the bottom plate of the flexible wheel cup. This paper is a static contact nonlinear analysis. Since the deformation of the flexible wheel is 0.5mm, the category of large deformation has been involved. Therefore, the large deformation option is called in the analysis option of the solution setting. The load step and time step are set to 1, and the automatic time is turned off. Step, turn on nonlinear analysis, and select the sparse-direct solver to solve.
