[Abstract]:The magnetic circuit structure of Mr shock absorber is an important link in the design of Mr shock absorber. The quality of the structure will directly affect the excellent performance of the damper. The parameterized simulation method is adopted. The influence of the key structure parameters of the magnetic circuit on the magnetic induction intensity of the gap magnetic circuit is obtained. According to the design objective, the design variables are selected. The simulation model of magnetic circuit is established. The optimization process of finite element analysis is introduced into the design of Mr shock absorber. The structural parameters of the model are optimized by parameterized language. The prototype of Mr damper is processed. The simulation analysis and experimental results show that the magnetic induction intensity at the gap is improved obviously after the optimization design of the magnetic circuit structure of the magnetorheological shock absorber by parameterized language programming. The magnetic field distribution is more reasonable and it is an effective method of magnetic circuit optimization.
