Abstract: To solve problems such as cumbersome testing process of brake system parts and many testing equipments, flexible closed-loop control system was developed to test key parts in brake system. At first, general control platform was established based on flexible closed-loop control system, and then mathematical model of flexible closed solenoid valve was set up. Furthermore, main influencing factors to the testing benchs precision were analyzed and some measures were taken to improve testing accuracy. By using event-driven, software reuse and component connections, testing software for brake system parts performance was developed. Based on parts input, control mode and technical index of brake system, flexible closed-loop control system was used on testing bench of brake system parts. Finally, the results demonstrated that the flexible closed-loop control system was both effective and reliable with good applicability.
