| View of the current China-made cars in parking brake operating handle assembly test system common control accuracy is low, a small test project, the phenomenon of low degree of automation, this paper, electromechanical servo-pneumatic servo-loop control technology to design their research.First of all, the paper operating handle assembly structure and working principle was analyzed ,and based on 46210-D82A0 parking brake control handle assembly test program pilot project evaluation criteria to determine an experimental system mainly consists of the impact strength test-bed, high-low temperature performance test stations and assembly strength test bench composed of three parts, respectively, by a control system to control it.Then the mechanical structure of the test system, loading system and measuring deformation measurement system has been designed, respectively.Finally, the electrical control part of the test system has been designed, and block diagram form of the test system through the workflow, the software control flow and the system software modules of the research and design.
