磁流变减振器阻尼特性半主动控制研究
Research on Semi-active Control of Damping Characteristics of Magnetorheological Damper
摘要
Abstract
A magnetorheological damper,known for rapid response,wide adjustment range of damping coefficient and low energy consumption,is a significant research direction in the field of vehicle engineering.By dynamically controlling the excitation current of the magnetorheological damper,we minimize the vibrations transmitted to the vehicle body,ultimately improving vehicle running smoothness.This research conducts a theoretical analysis of the hybrid-mode damping characteristics of a certain magnetorheological damper model.A multi-physics simulation model of the magnetorheological damper is developed using ANSYS to analyze the relationships among piston velocity,damping force and control current.A semi-active suspension and full-vehicle dynamics model is established,and a sliding mode control algorithm is applied in a Simulink numerical simulation to investigate the impact of control system on suspension and vehicle vibration performance.The research shows that the finite element analysis of the electromagnetic field provides a clear visualization of magnetic flux distribution,offering guidance for magnetic fluid flow path structural design.Additionally,the sliding mode control significantly enhances the performance of the semi-active suspension,effectively improving critical indicators such as vehicle body acceleration and suspension stroke.Ultimately the vibration characteristics,as well as ride smoothness and ride comfort of vehicles are significantly improved.关键词
