基于闭环力反馈原理的非线性液压主动阻尼悬架模型的研究及优化设计

本文在理论上建立了一套基于主动力反馈原理的新型主动阻尼悬架的设计和优化方法。首先提出了该主动阻尼悬架的实现模型，该模型是在传统的液力减振器的基础上，应用半主动控制的思想，结合力反馈的原理建立起来的内部液压反馈阻尼网络模型。理论优化分析和计算机仿真表明，通过该液阻网络模型，即可以实现电控的主动阻尼悬架的功能，它可以根据汽车行驶路况的好坏，自适应地调节悬架阻尼大小以实现主动阻尼悬架的最优控制。

A Study on Non-linear Hydraulic Active Damping Suspension and Optimal Design Based on Closed Loop Theory with Force Feedback

The paper proposes a set of theories for designing and optimizing a new type of active damping suspension based on the active force feedback principle.And physical embodiments of the concept are proposed,which are hydraulic damping network models established on the base of inner force feedback principle and combined with semi-active control scheme. Theoretical analysis and computer simulation show that the function comparable to that of electrically-controlled active damping suspension systems can be realized with the hydraulic network model,which can adaptively adjust the damping of suspension to achieve the optimal control of active damping suspension.
