Research and design of automatic comprehensive performance measurement system for hydraulic power steering gear

The performance of power steering affects the automobile driving safety directly. According to the fact that the power steering testing system can not meet the demand of production and design completely in domestic at present, the measurement system mainly used to test the performance of hydraulic power steering is developed. The working conditions of steering gear is simulated, this system can measure in real time and display the data of each sensor in measurement system and analyze, process, display, output and store the sampling data. By this means, the main technical performance parameters of the tested power steering can be measured accurately. The results of performing experimental test and metrology verification show that all the measuring accuracies are higher than the design requirements. The system runs steadily and the each testing item can realize reliably. The system can improve the product quality and reduce the development period.
