The invention relates to a platform for testing thermal fatigue characteristics of a part under a thermal shock load, and belongs to the technical field of testing devices. The platform includes a heater, a station exchanging device, a cooler and a controller. Linear guide rails are driven by linear cylinders to alternatively exchange a heating station and a cooling station for two workpieces so that the two workpieces can be cooled by the cooler. Surface temperatures of the workpieces or heating and cooling time can be set and adopted as control conditions, and the two workpieces can be tested simultaneously with one of the workpieces being heated and the other workpiece being cooled, and therefore the platform is simple, practical and efficient, can conveniently and rapidly test and research thermal shock and thermal fatigue strength for workpieces, can effectively shorten a test period, can effectively reduce the cost, and can increase test and research accuracy.
