Dynamic Characteristics Analysis And Research Of Motorcycle Damping System Based On Damping Control

Motorcycles have been developing for decades since their birth.Under the premise of satisfying the basic traffic function,the users now pay more attention to the safety and comfort of the vehicles,and the motorcycle vibration absorbing system plays a crucial role in this process.The shock absorber system mainly includes suspension system,tire and so on,and the suspension system directly influences the safety and comfort of the vehicle.This topic comes from the research and development project of Ningbo Safe Brakes Systems Co.,Ltd.In view of the fact that most of the motorcycles are equipped with ordinary double-cylinder shock absorbers,it is proposed to build a damped adjustable shock absorber to deal with different road conditions,so as to improve the riding comfort and safety.In this paper,the mathematical modeling method is used to establish the mathematical model of the recovery stroke and compression stroke of the solenoid valve damping damper,as well as the random pavement model and simulation verification.The Simulation X is applied and the electromagnetic valve damping is adjustable.The hydraulic model of the shock absorber is obtained with its dynamometer and velocity characteristics under different throttle opening degrees,and the damping force is determined.At the same time,using the knowledge of transfer function,the block diagram of the damping system is obtained.The transfer function model is built and simulated in Simulation X.The time domain characteristics,frequency domain characteristics and tracking characteristic curve of the motorcycle damping system are obtained.The seismic system can meet the basic conclusions of the design requirements,and has guiding significance for the control part of the motorcycle damping system.
