According to the design process of magnetorheological damper and the research results of the research group, the shimmy simulation platform based on Visual Basic 60 was established by the secondary development of CATIA and MATLAB. The platform had realized the friendly humancomputer interaction function, parameters were input according to the design demand, the backstage included the parametric modeling module, the theoretical calculation module and the shimmy simulation module, between the modules effective data exchange was realized, thus the structural design, parametric modeling and shimmy simulation of the front wheel of the aircraft were completed. The results show that the simulation platform can be used to complete the structure design,shimmy simulation and model drawing of the magnetorheological damper conveniently and quickly, and the operation is reliable, using the platform the development cycle can be shortened and the research and development costs of the damper can be reduced to a certain extent, which has a certain engineering significance.
