Test system

The invention provides a test system. The system comprises a support mechanism including a clutch assembly; an execution mechanism arranged on the support mechanism; and a control mechanism connectedwith the execution mechanism and used for controlling the execution mechanism to work; in the work process of the test system, a to-be-tested speed changer assembly is connected with a clutch assemblyand the execution mechanism; the control mechanism controls the execution mechanism to move to one side of the to-be-tested speed changer, thereby enabling a separation system of the to-be-tested speed changer assembly to move to one side of the clutch assembly, and to drive the clutch assembly to turn off the connection of the to-be-tested speed changer assembly and the support mechanism. The test system provided by the invention can simulate the actual use environment of the to-be-tested speed changer assembly, test the fatigue performance of the to-be-tested speed changer assembly, and improve the accuracy of the t
