摘要
针对最优常加速度控制方法在磁流变缓冲座椅系统中适用冲击强度范围小且不连续的问题,提出了最小峰值传递载荷控制方法(MPTL)。基于磁流变座椅系统的动力学方程,理论推导出系统在MPTL方法控制下的状态,并分析了MPTL方法的适用冲击强度范围及所需可控阻尼力范围;仿真分析了MPTL方法在不同冲击条件下的缓冲防护效果,并通过实验对仿真分析进行验证。结果表明,MPTL方法不仅可以最小化传递载荷的峰值,还对冲击强度和负载质量有较好的适应能力。
To address the issue of a limited and discontinuous applicable impact intensity range for the optimal constant acceleration(OCA)control method in magnetorheological(MR)seat systems,a minimum peak transmitted load(MPTL)control method is proposed.Based on the dynamic equations of the MR seat system,the state of the system under MPTL control is theoretically derived,and the applicable impact intensity range and the required controllable damping force range for the MPTL method are analyzed.The shock mitigation performance of the MPTL method under various impact conditions is evaluated through simulations,and the simulation results are validated experimentally.The results show that the MPTL method not only minimizes the peak transmitted load but also exhibits strong adaptability to different impact intensities and load masses.
