Abstract


With the constantly-depth study of the mechanical properties of materials or components, more and more engineering examples, just study the static mechanical properties is not enough, we must study its dynamic mechanical properties. The development of the testing machine is accompanied by a continuous in-depth study of the mechanical properties of materials or components and continuous development. Ordinary static testing machine only test or study can only be completed on the static mechanical properties, and can not complete the test or study of the dynamic mechanical properties. Emergence of electro-hydraulic servo static universal testing machine the international dynamic mechanical research field called one of the three major contributions to the developed countries already have their own movement of electro-hydraulic servo universal testing machine, our country is still in the blank stage, and therefore develop their own knowledge proprietary electro-hydraulic servo static universal testing machine, materials research field and even the defense of our country and of great significance. The subject in 1999, the project (key project of the State Science and Technology Commission 99-D064), 2001 12, 2010 by the Shandong Province Science and Technology Department of experts. Identification Committee that \The national initiative \Pre-tensile stress clamped elastic loosen the structural design of the beams. The high-speed, high-response, low damping, non-metallic support servo linear actuator. Ensure the full dynamic range of the test force completed pull test of hydraulic pressure forced chuck. Constant pressure servo pump station developed. This thesis is focused on the PWS-100A electro-hydraulic servo movement following the main part of the universal testing machine design analysis and calculation: the machine beams clamping calculation. Hydraulic forced chuck calculation. Servo linear actuator theoretical analysis. Optimal matching of the constant pressure the servo pump station and the servo valve design. Shandong Province Science and Technology Progress Second Prize was awarded after the completion of the project. The same time, due to the success of the project developed, the electro-hydraulic servo static universal testing machine has been completed the serialization and commercialization. PWS-100A electro-hydraulic servo movement the successful development of the universal testing machine of mechanics of materials research field provides its own means of research, make a due contribution to the country's aerospace, aviation and defense sectors.
