被动车辆悬架的性能可以在主动执行器的帮助下得到改善，但是，其控制要求可能存在问题，例如高能耗和大执行器力。为了在不需要大量控制工作的情况下最大限度地提高性能优势，需要对无源和有源部件进行设计并协同工作。本文提出了一种新颖的被动和主动组合振动抑制方法，该方法的被动部分通过惯性器增强，以改善动态性能和控制要求之间的权衡。通过这种方法，可以确定由预定数量的惯性器、弹簧和阻尼器组成的最佳被动配置以及最佳主动控制参数。该方法通过案例研究进行了演示，其中组合悬架的设计考虑了四分之一车模型和典型的主动控制器（即天钩控制）。结果表明，与弹簧阻尼器的传统被动部分相比，并联添加惯性器可以显着提高乘坐舒适性和功率（或力）要求之间的帕累托最优性。通过结构导抗技术系统地探索具有预定复杂性的所有无源网络可能性，进一步增强了改进。该方法也适用于其他工程结构的振动抑制。
Performance of a passive vehicle suspension can be improved with the help of an active actuator, however, with potentially problematic control requirements, such as high energy consumption and large actuator forces. To maximize performance benefits without requiring significant control efforts, the passive and active parts need to be designed and work synergistically. In this paper, a novel combined passive and active vibration suppression approach of which the passive part is enhanced by an inerter is proposed for improving the trade-off between dynamic performance and control requirements. Via this approach, the optimal passive configuration consisting of inerter(s), spring(s) and damper(s) with pre-determined numbers and the optimal active control parameter can be identified. The approach is demonstrated using a case study where the combined suspension is designed considering a quarter-car model and a typical active controller (i.e., the skyhook control). It will be shown that, compared with a conventional passive part of a spring-damper, adding an inerter in parallel can significantly improve the pareto optimality between the ride comfort and power (or force) requirements. The improvement is further enhanced by systematically exploring all passive network possibilities with a pre-determined complexity via the structure-immittance technique. This approach is also applicable to the vibration suppression of other engineering structures.
