摘要:

为实现液压互联ISD悬架全局工况最优,提出一种基于模糊控制的液压互联ISD悬架系统模式切换控制策略。研究液压互联ISD悬架系统工作原理,仿真对比液压互联ISD悬架两种工作模式力学特性,确定模式切换参数,并设计悬架工作模式识别以及模式切换控制策略,针对液压互联ISD悬架工作模式构建液压互联ISD悬架模糊控制器,并进行整车仿真分析,仿真结果与预期基本一致。在此基础上设计液压互联ISD悬架样机,进行台架试验,验证了所提出的液压互联ISD悬架系统模型的正确性以及模糊切换控制方法的有效性。

Abstract:

A strategy of model switch based on fuzzy control is proposed in order to meet the optimal performance of hydraulically interconnected inerter-spring-damper suspension (HIISDS), which during the global operating condition. The working principal of HIISDS has been briefly introduced at first, two different road excitations are used to validate the adaption of the two suspension modes, a parameter of mode switch is then derived through the simulation results. Second, mode switch strategy as well as mode recognition of suspension working modes are designed, the fuzzy controller which based on the mode switch has also been developed, and the result of simulation is basically consistent with expectations. Finally, a HIISDS suspension prototype is designed based on simulation results, and test results reconfirm that the fuzzy control of mode switch of HIISDS modes effectively.
