摘要

为能充分发挥惯容器作用，全面提升悬架性能。本文基于机械阻抗传递函数，对天棚控制算法进行推广，提出广义天棚理论，研究机械阻抗传递函数中刚度特性、阻尼特性及惯性特性对车辆悬架性能的影响。基于鱼群算法优化求解广义天棚结构并对其进行半主动实现。设计了一种可控惯容器装置，实现了惯性力的可控，并对其非线性进行了研究分析。结果表明，本文所提出的广义天棚控制半主动悬架，相比传统被动悬架和天棚阻尼控制悬架，能够进一步提升悬架性能，改善乘坐舒适性。

Abstract

In order to take the maximum advantage of the inerter and improve the performance of vehicle suspension, the general theory of skyhook control theory is proposed. Based on the mechanical impedance， the control strategy of skyhook is generalized. The impacts of stiffness, damper and inerter on the vehicle suspension are analyzed. The general skyhook structure is realized by semi-active suspension with the parameters optimized by fish swarm algorithm. A new controllable-inerter is designed and the nonlinear analysis is also carried out. The results show that the semi-active suspension with general skyhook control has better performance than traditional passive suspension and skyhook damper controlled suspension.
