Abstract

AbstractThe test bench driven by hydraulic servo has been widely used in the test of vehicle and parts, and plays an important role in automobile material test, new material research and development, product part structure design and quality monitoring. The mainstream suppliers in the field of automotive high-end hydraulic servo test equipment are foreign manufacturers, with serious technical blockade, difficult maintenance, long procurement cycle and high price of equipment body and accessories; in order to improve the test efficiency of automotive products and reduce the test cost, a set of high-precision automotive hydraulic servo test system is developed independently. Based on the basic principle of hydraulic servo control, the test system independently developed the test software, control accuracy reached the level of first-class hydraulic servo equipment, completed the fatigue life test of truck saddle, and provided guarantee for the performance and life test of subsequent vehicle and parts.KeywordsHigh-precisionHydraulicServoTesting system
