[0003] According to the novelty and industry knowledge, the attitude simulation and simulation of general products are usually realized by inertial navigation test equipment (turntable), but the attitude simulation test of large-scale flight equipment is often unable to be realized by the turntable due to the limitation of the turntable's own structure, so it is necessary to Designing a New Structural Form of Attitude Simulation

[0004] At present, in general, the attitude simulation test of large-scale flight equipment is completed on the six-degree-of-freedom platform, because the six-degree-of-freedom platform can usually meet the attitude simulation test of large size and heavy weight load, but because the six-degree-of-freedom platform is in the mechanism form There are inevitably singular positions on the ground, and it is difficult to achieve a large range of motion angles, so it cannot be applied to large-angle attitude simulation tests of large-scale flight equipment
