description	The invention discloses a test device for simulating load bearing of a joint. The test device comprises a main body unit, a swing unit and a variable loading unit, a glass disc simulates a hip joint of a human body, a test ball simulates a human joint head, a bionic cartilage layer simulates articular cartilage, and the test ball swings relative to the glass disc to simulate swing motion of the joint; the variable loading unit is used for changing the deformation degree of the loading elastic piece by controlling the positive and negative rotation and the rotating speed of the loading driver, applying a load meeting the ISO-14242 standard to the test ball, and capturing and recording an interference image generated between the test ball and the glass disc in real time by using the light interference measurement unit under a lubrication condition; relevant data processing is carried out on the collected image, a deformation curve of the thickness of the bionic cartilage layer is obtained, and the lubrication c
