摘要/Abstract

摘要：

针对某铰接式自卸车转向过程中出现的侧倾现象,设计了具有抗侧倾功能的模糊控制半主动油气悬挂系统，对其原理进行了阐述并建立数学模型对其特性进行了分析。结果表明，非模糊控制下的半主动油气悬挂系统满足其基本的性能要求。在该基础上针对自卸车某一转向工况下的模糊控制抗侧倾性能进行了分析,并运用Simulink中的fuzzy工具箱进行仿真。仿真分析与现场试验对比研究表明，采用模糊控制方式的油气悬挂系统有效地提高了系统的抗侧倾能力，这为工程机械油气悬挂国产化的研发提供了新的思路。

Abstract:

Aiming at the phenomenon of rolling over of an articulated dump truck when streering around, a semi-active hydro-pneumatic suspension system was designed based on fuzzy control with the function of anti-roll. The principles of the system were elaborated and the characteristic analysis was made with established mathematical model. It shows that the semi-active hydro-pneumatic suspension system meets the basic performance requirements in the condition of non fuzzy control. Based on this, the anti-roll analysis of the fuzzy control was also made and the simulation was applied using the fuzzy toolbox. Through simulation studies and field trials comparition,it can be concluded that the suspension system under the way of fuzzy control improves the system's anti-roll capability effectively, providing a new way of thinking for the domestic research and development of the hydro-pneumatic suspension system.

Key words: articulated dump truck, hydro-pneumatic suspension, characteristic analysis, fuzzy control, anti-roll
