[0002] In modern industrial production, hydraulic transmission is widely used in various mechanical equipment due to its high efficiency, reliability and strong adaptability. As one of the core components of the hydraulic system, the performance of the hydraulic cylinder (also called hydraulic cylinder) directly affects the stability and working efficiency of the entire system. Therefore, accurate testing and evaluation of the performance of the hydraulic cylinder is a key link to ensure product quality and system performance.

However, the accuracy of manual operation is limited by the operator's skill level and working status, and it is difficult to ensure the accuracy and consistency of the test data. Secondly, long-term manual operation is not only labor-intensive, but also inefficient, and cannot meet the needs of modern production for efficient and fast testing. Utility Model Content
