Abstract

The invention relates to a rubber fatigue tensile test bench and a rubber fatigue tensile test method. The test bench is composed of three parts, that is, an actuator, a data collection system and a control system, and the actuator comprises an overall fixing fixture, a force sensor, a left fixture, a right fixture, a sliding table, a support rod, a lead screw, a sliding table base, a coupling anda servo motor; the control system comprises a data collection card, a computer, a human-computer interaction interface and a PLC control system; the control system controls the rotation speed and direction of the servo motor through the PLC control system, so as to control the left fixture and the right fixture to load a rubber test sample; the rubber fatigue tensile test bench provided by the invention is simple in overall system composition, high in maneuverability and good in human-computer interaction; and further, a rubber fatigue tensile model obtained by using the rubber fatigue tensile test method provided by the invention is more accurate compared with that in the prior art.

Description

technical field [0001] The invention relates to a rubber fatigue tensile test bench and a rubber fatigue tensile test method. Background technique [0002] As an irreplaceable elastic material, rubber has been used for more than 160 years and has been widely used in national defense and economic construction. Rubber is not only an indispensable substance in life, but also a high-performance and functional material necessary for the development of high-tech. In order to achieve the purpose of vibration reduction, noise reduction, flexibility and wear resistance, rubber is often compounded with metal to make elastic elements, which are widely used in many high-precision fields. Rubber components usually work under cyclic stress, and the fatigue fracture performance of rubber materials often determines the fatigue life of components. With the increasingly harsh service conditions of rubber products, the problem of rubber fatigue failure has become increasingly prominent and n...
