摘要
利用Rebrouck建模方法,建立了液压减振器的动力学模型,该模型反映了位移、速度、加速度、频率和温度等因素对减振器阻尼力的影响.使用Levenberg-Marquardt优化算法,利用某型号ATV(all terrain vehicle)右后减振器试验数据对活塞阀特性参数进行了辨识,模型计算值和试验数据吻合良好.将该减振器动力学模型以S-function的形式集成到CarsimTM的某E-class整车模型中,在扫频路面和双移线工况下研究了减振器动力学模型和速度-阻尼力曲线模型对车辆动力学响应的影响.
This paper details a dynamic shock absorber model using the Rebrouck method,the influence of displacement,velocity,acceleration,frequency,and temperature on damping characteristics is considered.The constituent parameters of an ATV＇s right-rear shock absorber are obtained using Levenberg-Marquardt optimization algorithm and five group experimental data,and the test data agree well with the calculation.Finally,the dynamic model is incorporated into an E-class full vehicle model（CarsimTM） using S-function.The vehicle＇s behaviors are compared with the results obtained with the classical shock absorber representations under frequency sweep and double lane change conditions.
