AI Technical Summary
Existing hydraulic testing platforms cannot meet the testing needs of robot-specific hydraulic drive systems. In particular, the dynamic characteristics requirements under miniaturized and refined operations have not been fully considered, and there are significant deviations between the simulated working conditions and the actual working scenarios. The nonlinear characteristic evaluation dimension is too single, making it difficult to accurately verify the performance of the hydraulic system under dynamic coupling conditions.
A hydraulic drive dynamic performance verification test device is provided, including a hydraulic system, an inverted pendulum hardware system, and a data acquisition and feedback system. The inverted pendulum structure simulates nonlinear working conditions, and the inverted pendulum hardware system and data acquisition and feedback system are integrated to achieve rapid switching between full-drive and under-drive test modes, construct a multi-dimensional performance evaluation system, and combine the inverted pendulum structure and data acquisition and feedback system to conduct accurate testing of the hydraulic system.
It enables accurate verification of hydraulic drive systems under dynamic coupling conditions, adapts to the testing needs of small hydraulic robots, solves the problems of large-scale structure and cumbersome disassembly and assembly of existing platforms, provides multi-dimensional performance evaluation, helps R&D personnel to deeply understand the mechanism of nonlinear characteristics, and improves testing efficiency and reliability.
