Fatigue testing device of damping pad

Abstract

The invention discloses a fatigue testing device of a damping pad. The fatigue testing device comprises a temperature box, a left fixing plate, a load bearing plate and a right fixing plate are arranged in the temperature box at intervals from left to right, multiple supporting rods are penetratingly arranged at the edges around the left fixing plate, the load bearing plate and the right fixing plate at intervals, a dynamic load hydraulic actuator is fixedly arranged on the right side wall of the left fixing plate and connected with a dynamic load force sensor which is connected with the left side wall of a dynamic load pressurizing plate, a static load pressurizing plate is arranged exactly on the right of the dynamic load pressurizing plate, and the damping pad is placed between the static load pressurizing plate and the load bearing plate; a static load hydraulic actuator is arranged on the left side wall of the right fixing plate and connected with a static load force sensor, and the left end of the static load force sensor is connected with the static load pressurizing plate. By the fatigue testing device, test operating personnel can conveniently and reliably test temperature stress and fatigue load of the damping pad, and testing cost is lowered remarkably.

Description

technical field [0001] The invention relates to the field of fatigue test technology, in particular to a fatigue test device for shock absorbing pads. Background technique [0002] At present, the fatigue test device is a device that subjects the sample or component to periodic or randomly changing stress or strain to measure the fatigue limit and fatigue life. Before the product is put into use, it is necessary to carry out sufficient fatigue performance test and assessment in the laboratory to measure the fatigue limit and fatigue life of the product, so as to ensure that the product will not experience fatigue damage and failure during actual use. [0003] For the elevator, the material of the shock-absorbing pad is rubber, and the shock-absorbing pad plays the role of cushioning and shock absorption during use. Due to the different environments, the shock pad will not only be subjected to mechanical shock and alternating fatigue loads, but also be affected by temperatur...

Problems solved by technology

[0004] However, the current device can only detect the temperature stress of the shock absorber alone, or carry out the fatigue load test alone, so multiple devices need to be configured, which not only takes up a lot of test space, but also requires test operators to be familiar with multiple One device, which brings great inconvenience to the daily use of test operators
