The Study of Automobile Brake Chamber Performance Test System

To solve the problem of measuring the brake chamber at present, this integrative performance test system for bake chamber was built up by using the computer control technology. It can measure these parameters: dynamic characteristic, static characteristic, sealing performance and return performance. To verify the system accuracy, a multi-parameter dynamic simulation model for the brake chamber was designed based on AMESim. It breaks through the limit which was formerly difficult to analyze the defects of the theoretical parameters for brake chamber. By the simulation models and test system, the influence of the key component parameters to the output characteristic is analyzed .The experiment results show that the integrative performance of brake chamber can be judged very well and the simulation model is accurate and reliable.
