Multifunctional environmental device for fatigue testing

Abstract

The present invention belongs to the component fatigue testing field and relates to an environmental device for fatigue testing, in particular, a multifunctional environmental device for fatigue testing. The multifunctional environmental device for fatigue testing comprises a frame and control cabinets; the frame is a cube frame; the environmental device further comprises heating modules, cooling modules and salt mist spray assemblies; the bottom surface of the frame is provided with a water receiving cover plate in a sealed manner; any one of the side surfaces of the frame is equally divided into a plurality of module mounting positions; the heating modules and/or the cooling modules are inserted in the module mounting positions; the other side surfaces and top surface of the frame are provided with sealing cover plates; the salt mist spray assemblies are mounted on any one or more sealing cover plates; and the control cabinets are connected with the heating modules, the cooling modules and the salt mist spray assemblies. According to the multifunctional environmental device for fatigue testing of the invention, modular design is adopted, a proper number of modules can be combined according to different test requirements, and therefore, the environmental device has high universality, can satisfy the test requirements of various special environmental conditions, greatly improve test efficiency and reduce test cost.

Description

technical field [0001] The invention relates to the field of component fatigue tests, in particular to an environmental device for fatigue tests. Background technique [0002] At present, the environmental simulation devices used for fatigue testing of auto parts, including high and low temperature and salt spray, are usually customized for specific tests and designed for specific equipment, with low utilization rate, high cost and limited scope of use. Due to the variety of component structures, most of the existing environmental chambers are integral, which easily hinders the installation of samples, fixtures and fatigue testing machines, and cannot adapt to different types of test requirements. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a multifunctional environmental device for fatigue testing. Through the combined modular design, an appropriate number of heating modules, cooling modules and salt sprayin...
