The high pressure oil is used to be the power source of the machine ,generally above 200KN. The pressure testing machine in this topics is mainly used for large-scale structure of the mechanical. The of properties of the test machine is good or bad will directly affect the actual test results and the quality of the projects. Through literature review, workshop practice and a careful analysis of the way and summary of the overall framework and the main structure of the existing pressure testing machine, besides the achieve dynamic function of the system, combined with the technical parameters of the design requirements of the mission statement to complete the design of the project. These include 1. host design, including the fuel tank design, rack design, test design space adjustment method. 2. Oil Source. 3. Send oil valve, oil return valve design. Calculated by a three-month design, I can master the hydraulic pressure testing machine structure, and able to master the basic principles and methods of the mechanical system design and hydraulic system design , al
