Rubber Bearing Two-dimensional Static Load Test

With the growing demand for isolation rubber bearing in the market, the load test machine of isolation rubber bearing is used more and more widely and the requirements of the test machine are becoming higher and higher.The detection system and method for mechanical properties of isolation rubber bearing were researched in this paper. The requirements for the load test machine of isolation rubber bearing were put forward in this paper and the machine was developed successfully. The main research results are composed of the following aspects.(1)The Electro-hydraulic Servo Actuator with the capacities of a 2,500 tons of vertical static thrust and a 300 tons of horizontal static thrust was designed in this paper.(2)The rack which can carry 2,500 tons of vertical force or 300 tons of horizontal force in the loading test was designed successfully.(3) The horizontal scrolling device for horizontal shear test and the automatic delivery sector for samples were designed successfully.(4)The hydraulic servo oil source system with a rated flow of 1000L/min and a 5000L accumulator was designed successfully, which can produce 28Mpa compressive stress.(5)The control system for loading with a all-digital servo and data acquisition system were designed successfully.On the principle of economy, rationality and convenience, the test machine adopted the internal force self-balancing system and was designed by the method of framework.The structure of the machine is more rational,which absorbed the related technical characteristics of Japan's compression and shear testing machine and combined with the design experience of Zhouzhou Times New Material Technology Co.,Ltd.
