Design of Performance Testing Bed for Hydraulic Products of Engineering Machinery

Abstract

Hydraulic test platform is a very important testing tool for hydraulic products of engineering machinery. In this paper, a new type of hydraulic test bed is developed which can be used for performance testing of hydraulic valves, hydraulic motor and hydraulic pump. The composition structure diagram of hydraulic system, power supply system, and the signal flow diagram of data acquisition system were designed. The communication between sensors and computer via RS232 were researched. At last, the hydraulic test software is developed by using Labwindows/CVI and Simense PLC.
