摘要: 减震器销的设计对洗衣机的使用和装配性能影响较大,为了研究其影响规律,采用有限元分析方法得出设计参数(外径、开口槽宽、卡扣高度、堵高)对减震器销的装配力和平均接触压力的影响。针对减震器销的装配仿真分析,通过网格收敛性及结合实验对仿真精度进行验证,研究了减震器销装配仿真的分析方法。通过对不同设计方案的减震器销进行有限元分析,优选出最佳方案,提升装配后的接触压力以提高装配可靠性,拥有较低的装配力和较好的可制造性,为减震器销设计提供量化分析指导。

Abstract: The design of damping pin has great influence on the use and assembly performance of washing machine. The finite element analysis is used to study the influence of design parameters (outer diameter, opening groove width, buckle height, plug height) on the assembly force and mean contact pressure of damping pin. Aiming at the assembly simulation analysis of shock absorption pins, the analysis method of assembly simulation of shock absorption pins was studied through the verification of grid convergence and simulation accuracy combined with experiment. Through the finite element analysis of the damping pins of different design schemes, the best scheme was selected to improve the assembly reliability by increasing the contact pressure after assembly, with lower assembly force and better manufacturability, providing quantitative analysis guidance for the design of damping pins.

Key words: Damping pin, FEA, Assembly simulation, Interface assembly
