A device for performing metal material fatigue experiments on a vibrating table

Abstract

The invention discloses a device for carrying out metal material fatigue experiments on a vibrating table, which comprises a vibration testing platform. The four end corners of the bottom surface of the vibration testing platform are fixed with short posts, and the bottom of the short posts are fixedly connected to There is a replaceable spring assembly, the bottom end of the replaceable spring assembly is fixedly connected with a long support column, wherein a motor support connecting plate is fixedly connected between two of the long support columns, and the other two long support columns A shaft sleeve connection plate is fixedly connected between them, a stepper motor is fixedly installed in the middle of the outer surface of the motor support connection plate, and a long sleeve located under the vibration test platform is fixedly installed on the top of the stepper motor through a coupling. shaft, the top of the long sleeve shaft passes through the sleeve connecting plate and is connected with the sleeve connecting plate through a roller bearing. The invention can carry out the vibration test of the product and the bending fatigue test of the product at the same time, and the overall mechanical adjustment is convenient.

Description

technical field [0001] The invention relates to the technical field of fatigue testing machines, in particular to a device for fatigue testing of metal materials on a vibrating table. Background technique [0002] With the rapid development of social economy, there are more and more applications for vibration testing of electronic equipment or fatigue testing of materials. Fatigue testing machine is a method mainly used to measure the tensile strength, It is a machine for fatigue performance testing of compression or tension and compression alternating loads. The fatigue testing machine is characterized by high load, high frequency, and low consumption, thereby shortening the test time and reducing test costs. The fatigue testing machine is used to measure metals and alloys. Fatigue characteristics, fatigue life, pre-crack and crack growth tests of materials and their components under tension, compression or tension-compression alternating loads at room temperature.
