Description

technical field [0001] The invention relates to the field of hydraulic testing, in particular to a hydraulic test bench for an electrostatic fluid actuator. Background technique [0002] Electrostatic hydraulic actuator is a new type of power-by-wire system, which has an independent hydraulic source inside and integrates mechanical, electrical and hydraulic technologies. Compared with traditional hydraulic systems, it eliminates the complicated pipelines and Mechanical structure, high integration, more complex testing. At present, most of the test benches for electrostatic fluid actuators are controlled and tested manually, which has low test accuracy, low degree of automation, and low test efficiency. The invention designs a novel hydraulic test bench for the electrostatic fluid actuator, which can carry out fully automatic testing of the electrostatic fluid actuator. Contents of the invention [0003] The purpose of the patent of the present invention is to provide a h...
