传统的减震器通过粘性油阻尼器将大量振动能量耗散为热量浪费。为了收集这种能量并提高车辆悬架性能，引入了一种新型能量收集减震器，该减震器使用机械运动整流器（MMR）和基于规则的控制器，以提高车辆乘坐舒适性以及在不同粗糙度等级的随机道路激励下收集的能量。将基于规则策略的受控MMR减振器与被动减振器、天钩策略受控传统减振器以及SH-PDD（天钩动力驱动阻尼器）策略受控MMR减振器的平顺性性能进行了比较。基于规则的MMR减震器展现出最佳的乘坐舒适性性能。
Traditional shock absorbers dissipate large amount of vibration energy into heat waste via viscous oil dampers. To harvest such energy and improve the vehicle suspension performance, a novel energy-harvesting shock absorber that uses a mechanical motion rectifier (MMR) is introduced with a rule-based controller to improve vehicle ride comfort as well as harvested energy under the random road excitations with different roughness classes. The ride comfort performance of the controlled MMR shock absorber with rule-based strategy is compared with the passive shock absorber, the controlled traditional shock absorber with skyhook strategy, and the controlled MMR shock absorber with SH-PDD (skyhook-power driven damper) strategy. The rule-based MMR shock absorber shows the best ride comfort performance.
