Abstract

The invention relates to thermal shock examination experiment testing platform of a transverse rotary movement of test pieces, and belongs to technical field of test equipment. The platform comprises a testing stand support, a position sensor II, a position sensor I, a linear cylinder I, a thermal insulation cavity, a clamp I, an infrared temperature-measurement instrument I, an infrared temperature-measurement instrument II, a clamp II, a cooler, a straight rod I, a straight rod II, a position sensor III, a linear cylinder II, a position sensor IV, a guide rail and a swinging cylinder. The two test pieces can be tested at the same time, the one is heated, and the other is cooled; and the two test pieces rotate for 180 degrees under the drive of the swinging cylinder, and then the two test pieces rotate with the guide rail to exchange working stations under the drive of the swinging cylinder. The platform is simple and practical, and has high working efficiency; and, when an internal combustion engine piston thermal shock and thermal fatigue simulation test is studied, a test expense is saved, and research and development periods of related parts are also greatly shortened.

Description

technical field [0001] The invention relates to a thermal shock assessment test platform for lateral rotation of a test piece, which is applied to a test platform for thermal fatigue strength assessment of internal combustion engine test pieces and other mechanical heating parts, and belongs to the technical field of test equipment. Background technique [0002] In engineering structures and mechanical equipment, the phenomenon of thermal fatigue damage is extremely widespread, and it pervades every component that is heated and moved. Due to the lack of obvious macroscopic plastic deformation, the thermal fatigue failure is very sudden, which often causes catastrophic accidents and huge economic losses. As far as the internal combustion engine is concerned, with the development of science and technology, the development of the engine towards the direction of high reinforcement and high supercharging and the popularization and application of technologies such as multi-valve s...
