A motion simulator comprises a base, a motion platform, a carrying platform, a support assembly and a driver assembly for simulating different motions. The motion platform is movably connected to the base, the carrying platform comprises a carrier arranged on the carrying platform, the support assembly is movably connected to the motion platform and the carrying platform, and the driver assembly drives the motion platform to move relative to the base and drives the actuator to actuate the carrying platform to move relative to the motion platform. The support assembly further includes an actuator and a support tube that are movably connected between the motion platform and the carrying platform, respectively.
