The invention provides a multi-specimen abrasion test device. The multi-sample abrasion test device comprises a high-pressure kettle, sample holders, stationary sample holders, loading springs, flexible hinges, a mounting frame of the sample holders and a driving rod, wherein the sample holders comprise the stationary sample holders and moving sample holders; the stationary sample holders, the moving sample holders and the loading springs are arranged in the high-pressure kettle, and the driving rod connected with the moving sample holder penetrates through a cover of the high-pressure kettle so as to provide driving force for the moving sample holders; the sample holders are arranged in the high-pressure kettle through the mounting frame of the sample holders. The multi-sample abrasion test device has the advantages that the abrasion test can be performed under the high-temperature and high-pressure solution environment; by arranging multiple samples at one time, the test efficiency is improved; by adopting the springs to load a stationary sample, the loading control of the sample in the high-pressure kettle is simplified; by measuring the displacement and load on the driving rod at the exterior of the high-pressure kettle, the displacement of friction movement is controlled, and the displacement and friction force can be measured.
