Material thermal and mechanical loading performance testing device

Abstract

The invention provides a material thermal and mechanical loading performance testing device, which comprises a box body, a sliding door, a power switch, a temperature strain display, a current adjusting knob and a voltage and current display are arranged on the box body, a fixed support, a sliding support, a screw rod, a strain gauge and a thermocouple are arranged in the box body, the fixed support is fixed at the bottom of the box body, the sliding support is connected with the bottom of the box body through a sliding rail, the screw rod is rotationally connected with the fixed support and is in threaded connection with the sliding support, a first clamp and a second clamp are respectively fixed on the fixed support and the sliding support in an insulating manner, and heating wires are respectively arranged on the first clamp and the second clamp. According to the invention, simultaneous thermal and mechanical loading of the material is realized, direct loading is carried out through current, the temperature rise time is long, real-time adjustment is carried out through a current adjusting knob and a thermocouple, the loading parameter control is accurate, and the operation is convenient; in addition, the synchronism of thermal loading and mechanical loading is good, the actual working condition can be conveniently and accurately simulated, and the test error is small.

Description

technical field [0001] The invention relates to the technical field of material performance testing, in particular to a material thermomechanical loading performance testing device. Background technique [0002] With the technical development of aero-engines, the performance requirements of aero-engines have been gradually increased in the design and test. In the process of engine development, it is very important to accurately grasp the characteristics of materials used in various structural parts, especially in the development of new materials, it is necessary to use heating and loading tests to make a preliminary understanding of the characteristics of materials. At present, the material heating and loading test of aero-engines is carried out separately by oil temperature heating and fatigue machine loading. The heating and cooling time is long, and the synchronization is poor. It cannot accurately simulate the actual working situation, and the test error is large. Cont...
