Mechanical-thermal synergistic accelerated aging test platform

Abstract

The invention discloses a mechanical-thermal synergistic accelerated aging test platform which comprises a fixing frame, a synergistic mechanism is mounted at the center of the inner side of the fixing frame, and the synergistic mechanism comprises a modal vibration exciter, an output screw, an aging oven, a placement cavity, a square container, a test material, a guide rod, a guide hole, a first pressing plate, a second pressing plate and a force sensor. According to the invention, through the temperature and humidity controller in the aging oven, the monitoring and control of temperature and humidity can be realized conveniently, the requirements of various test conditions can be met, through the action of the modal vibration exciter, excitation forces with various waveforms and frequencies can be output, the excitation forces can be automatically adjusted according to test requirements, the application range of the platform is expanded, and the test efficiency is improved. Meanwhile, through cooperation of the modal vibration exciter and the aging oven, compared with an existing test platform which can only conduct single-factor aging, the mechanical-thermal synergistic accelerated aging platform can greatly shorten the test time and improve the test effect.

Description

technical field [0001] The invention relates to the technical field of aging test, in particular to a mechanical-thermal synergistic accelerated aging test platform. Background technique [0002] In many scientific experiments, it is necessary to carry out aging tests on materials. According to the different operating environments of materials, aging tests on materials are carried out, such as thermal aging, mechanical aging and electrical aging. Due to the slow speed of the actual aging process, the aging time is relatively long , in scientific experiments, it is often necessary to increase the aging rate in order to shorten the test time, thus deriving a variety of aging test platforms; [0003] However, most of the existing accelerated aging platforms only consider a single factor aging, such as a single accelerated thermal aging platform or a single accelerated mechanical aging, so that the accelerated thermal aging can only be performed first and then the mechanical agi...
