The Integrated Testing System for Performance Parameters of the Hydraulic Excavator

Abstract

This paper designed and developed an integrated testing system for performance parameters of the Hydraulic excavator. Combined with sensing technology, computer technology and virtual instrument technology this system can detect six key parameters of the excavator including motor speed, hydraulic system pressure, attachment action time, swing speed, walking speed, current characteristics, so as to evaluate the performance of the excavator. The testing system takes full consideration of the interaction between the tester and driver, meanwhile, can automatically detect all parameters by using the parallel test method in order to make sure the whole test completed in one hour. As the testing system is designed base on the idea of modularization, it can add new modules to meet the functional requirements alone with the development of research in the future. This testing system can not only improve the test efficiency, but also be used as analysis tools for the research and optimization of performance parameters of excavators.
