摘要

摘要: 键合图理论用统一的方式处理多种能量形式,广泛应用于机电系统的建模和仿真。本文在建立电、液转向系统诊断键合图模型的基础上,推导出解析冗余关系ARRs,解算出系统残差并用于故障诊断。在物理系统中安装集成多型号传感器的信号采集网络,实现物理系统运行参数的在线采集,通过车辆转向系统的故障诊断进行实例分析及检验,验证了该诊断方法的正确性和有效性。

Abstract: Bond graph method is widely used in the modeling and simulation of mechatronic systems since it using a uniform manner to handle multiple forms of energy. Based on building bond graph models of electrical-fluid system, this paper constructs a signal acquisition net by installing multiple sensors, which can realize operation signal online collection, and deduce ARRs (Analytical Redundancy Relation) to calculate residual of physical system for FDI. Fault diagnosis experiments are performed on a vehicle steering system, and results indicate the correctness and practicality of designed FDI system.
