Abstract: The material test machine masurements have disadvantages of monofunction and complexity for adding new testing programs. In order to solve these problems, the Delphi language based software development technology and microcontroller based automatic control technology were applied in the machine universal testing machine control system. The experimental standard for tension and compression of common materials were analyzed, and the requirement of the experimental procedure for universal testing machine was investigated. Based on these, the modular software and hardware design method was proposed to establish the upper computer software and lower computer hardware and software platform. Based on the platform, the multiobjective holding test examination, the compression tests of cement mortar and metal tensile test were experimented. The results show that the proposed modular design technology for the control system of the universal testing machine could solve the problem mentioned above and achieve a simple and flexible control system.
