The invention relates to the technical field of spacecraft vacuum thermal tests, in particular to a spacecraft vacuum thermal test motion simulation device, which comprises a base, a pitching mechanism, a rotating mechanism and a transmission monitoring assembly, and is characterized in that the pitching mechanism is arranged on the base; the rotating mechanism is arranged on the pitching mechanism and connected with the pitching mechanism, and the rotating mechanism can drive the load to rotate around the first axis; the pitching mechanism drives the rotating mechanism to swing around a second axis, so that the load can swing around the second axis; the transmission monitoring assembly is connected with the rotating mechanism and used for detecting whether the power input end of the rotating mechanism and the power output end of the rotating mechanism conduct synchronous transmission or not. According to the application, the power input end of the rotating mechanism and the power output end of the rotating mechanism can be ensured to keep synchronous transmission in the test process, so that when the rotating mechanism rotates at a certain speed, the load can be effectively ensured to complete the operation at a set angle within a set time, thereby restoring the trueness of the vacuum thermal test of the spacecraft, and improving the test efficiency. And the accuracy of test data is improved.
