Research And Realization Of Universal Hydraulic Testing Machine Controlled By Computer

Hydraulic Testing Machine(HTM) is the most useful testing device. It can ensure quality of product and project . It used in machine,energy source,traffic and so on. Design purpose of Computer Control Hydraulic Testing Machine (CCHTM) is to design a precision measure and control system of load ,extension,crosshead. It can do many test, such as pull, compress, curve and so on. It will become a copyright product of my company(1).Basic principleCCHTM mainly include three parts: software, hardware, mechanism.1. Hydraulic mechanism principleHTM's power come from oil pump. When oil pump push oil to servo clique, oil flux can be handly control by man or automaticly control by computer to pass servo clique. It can control piston up or down,...
