The main reason that restricts the development of hydraulic excavators in China is the lack of advanced and effective test methods and equipment, which leads to many key parameters and indicators in the process of design and manufacturing can only be simulated, and can not carry out accurate and precise quantitative analysis and design. The development of comprehensive performance test platform for hydraulic excavators can provide a basic test platform for hydraulic excavators. Based on this platform, a variety of performance tests can be carried out, providing scientific theoretical basis and experimental data for the research and development, manufacturing, assembly, debugging, inspection and other work of hydraulic excavators, which is helpful to break through the core technology of hydraulic excavators, Improve its reliability, promote its large-scale development, so as to further promote the rapid development of Chinese national brand excavator. Moreover, compared with the field operation test, using the test platform for simulation test and research conforms to the repeatability, consistency and comparability of the scientific test results, and can avoid the impact of the instability of the actual operation on the test results. It can be said that the development of hydraulic excavator performance comprehensive test platform is the basis of high-level test and high-level research and development of hydraulic excavator, which has strong social benefits, economic benefits and very important significance.
