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.
