%X 以考虑轮胎阻尼的四分之一车辆模型为基础，在簧下质量上引入调谐质量系统以回收车辆垂向振动能量。针对所构建的分析模型，推导了系统动力学方程。将路面不平度视为随机速度激励，应用动力吸振器设计的H2优化方法确定调谐质量系统的参数。为评价调谐质量系统的影响，在车辆动力学性能评价指标之外，基于阻尼耗散及其变化定义了总体耗散能、调谐系统能量回收潜力、车辆阻尼耗散能等指标。针对某车辆参数进行仿真计算，从车辆性能与能量变化等角度探讨了应用簧下调谐系统回收车辆振动能量的可行性，并进行了参数影响分析。结果表明：引入簧下调谐系统能够在改善车辆动力学性能的同时回收来自轮胎和悬架的振动耗散能量。<br>Abstract：A quarter car model with tire damping was used to analyze vibration energy harvesting with a tuned mass damper (TMD) system with an unsprung mass. With the road roughness as a stochastic velocity excitation, H2 optimization of the dynamic vibration absorber (DVA) was used to determine the system parameters. The model predicted vehicle dynamics indices and energy indices defined based on the energy consumption to evaluate the system impact. The energy indices included the overall dissipated energy, the system energy harvesting potential, and the dissipated vehicle energy. The model was also used for a sensitivity analysis of the system parameters. The results show that attaching a system with an unsprung mass can harvest vibration energy from both the suspension and the tire.
