摘要
磁流变变刚度变阻尼扭转动力吸振器(MR-VSDTVB)为实现动力传动系统扭转振动的有效半主动控制提供了思路.为此,建立了可变刚度和阻尼的汽车动力系统扭转振动动力学模型,加速工况下研究磁流变吸振器不同刚度和阻尼对系统输出响应的影响规律;进而,基于AMEsim和MATLAB/Simulink联合仿真,分析动力系统在加速工况下半主动控制对系统扭转振动的抑制效果,验证磁流变变刚度变阻尼扭转动力吸振器对动力传动系统扭转振动抑制的有效性.
Based on magneto-rheological(MR)technology,the MR variable stiffness and damping torsional dynamic vibration absorber offers possibilities for the semi-active control of torsional vibrations in powertrain systems.Therefore,a torsional vibration dynamics model of a variable stiffness and damping automotive powertrain is developed to investigate the laws of different stiffness and damping of MR vibration absorbers on the output response of the system during speed-up operation.In addition,based on AMEsim and MATLAB/Simulink combined simulation,the torsional vibration suppression effect of semi-active control on powertrain system under speed-up operation is assessed to validate the effectiveness of MR variable stiffness and damping torsional dynamic absorber on the torsional vibration suppression of powertrain system.
