Abstract

The invention relates to a hydraulic system component reliability test device and method including an environment field, and belongs to the technical field of hydraulic system component reliability tests. A monitoring device is fixed on the upper surface of a three-dimensional vibration platform. An electro-hydraulic servo device, a connection device and a hydraulic cylinder assembly are aligned through a base plate and fix the base plate to a support framework. A three-position four-way electromagnetic reversing valve and sensors are installed on the upper surface of the support framework. The hydraulic cylinder assembly and the three-position four-way electromagnetic reversing valve are connected through a connection oil pipe. A temperature and humidity control box assembly is installed on the upper surface of the three-dimensional vibration platform. Weak links in the hydraulic system are found out by the simulation of practical conditions, the dynamic force and static force loading tests and collision tests of the hydraulic system are completed through the electro-hydraulic servo device, so that corresponding parameters of faults are obtained, the design of the hydraulic system is facilitated, and the reliability of the hydraulic system is improved.

Description

technical field [0001] The present invention relates to a test device and a reliability test method in the technical field of reliability test of hydraulic system components (joints, pipelines, valve bodies, hydraulic cylinders) including environmental factors. The three-dimensional vibration platform, the temperature and humidity chamber and the loading device realize the hydraulic system under different temperature, humidity, vibration and pressure conditions, and carry out the loading test on the hydraulic system so as to simulate the reliability test device and method of multiple working conditions. Background technique [0002] With the continuous development of the manufacturing industry, CNC machine tools have become an essential tool in the manufacturing industry, and the hydraulic system is a prerequisite for the normal operation of CNC machine tools. Hydraulic systems are widely used in modern industrial fields, especially in construction machinery, lifting devices...
