Abstract

A compound hydraulic oscillating cylinder for electro-hydraulic servo loading systems comprises a loading cylinder consisting of a loading cylinder output shaft, a thrust bearing, a loading cylinder shell, left and right loading cylinder end covers, and a seal set. The loading cylinder shell is used as a synchronous cylinder spindle. A synchronous cylinder shell, another thrust bearing, a left synchronous end cover and a seal set are disposed on the synchronous cylinder spindle to form a synchronous cylinder. The compound hydraulic oscillating cylinder is compact in structure, low in rotation inertia and reliable in tightness. Force / position coupling of the electro-hydraulic servo loading systems can be achieved basically, and loading precision and frequency response of the systems are increased.

Description

technical field [0001] The invention relates to a hydraulic actuator in the technical field of mechanical engineering, in particular to a compound hydraulic swing cylinder used in an electro-hydraulic servo loading device. Background technique [0002] Because the hydraulic servo system has the outstanding advantages of large power-to-weight ratio, good rapidity, and fast system response, it has incomparable advantages over the electric servo system in the application fields that require high power, high precision, and high response. The electro-hydraulic servo loading system is an important part of the hydraulic servo application field. It is mainly used for material performance test devices, load simulation devices for aerodynamics, hydrodynamics, various resistances, etc., earthquake simulation vibration tables, etc. The key technical issue of the electro-hydraulic servo loading system is how to suppress and eliminate the positional disturbance caused by the deformation o...
