The invention relates to a test platform in a vacuum cabin, belongs to the technical field of aerospace liquid attitude and orbit control engine test, solves the technical problems of low bearing capacity and poor flexibility of the test platform, and comprises a basic platform, a frame structure and a moving mechanism which are sequentially connected from bottom to top. The foundation platform is fixed to a foundation and comprises a platform face, supporting stand columns, connecting pipes, corrugated pipes, base plates and foundation bolts. The frame structure is installed above the foundation platform, fixedly connected with the foundation platform through bolts and used for transmitting thrust of the engine to the foundation platform and supporting the engine to a certain height. The moving mechanism comprises a fixed guide rail, a guiding guide rail, a moving trolley, a sliding block, a steel ball and a bolt and is used for installing the thrust measuring device and the engine. The device is used for the high-altitude simulation test of the aerospace liquid attitude and orbit control engine.
