Description
Technical Field
The invention belongs to the technical field of motion simulation, and particularly relates to a high-rigidity-weight ratio O-U type vertical double-shaft motion simulator.
Background
The motion simulator with the double-shaft rotation function is suitable for motion simulation of two postures (pitching and azimuth). Generally, for a biaxial motion simulator, there is a T-U-shaped horizontal type structure, i.e., an inner frame structure is T-shaped, providing a posture simulation of azimuth, and an outer frame structure is U-shaped, providing a posture simulation of pitch. The rotation axis of the outer frame is parallel to the ground, namely, the horizontal structure type. Such T-U horizontal structural versions are typically heavy in weight and difficult to achieve with high stiffness to weight ratios. Another type of structure is also an O-U type vertical structure, but the load bearing is mounted on the ring of the O-frame. The O-U type vertical structure can only bear a specific load of a cylinder type, has limited application range, and is difficult to meet the motion simulation requirements of two postures (pitching and azimuth). Moreover, the two traditional structure types of double-shaft motion simulators are generally complex in internal shafting structure, and finally cannot be placed on other motion platforms (such as an air floatation platform) due to the fact that the whole machine is heavy in weight, namely cannot be combined with other motion platforms to simulate more gesture motions. When the biaxial motion simulator is combined with other motion platforms, higher requirements are often put on the natural frequency of the biaxial motion simulator, and resonance cannot be generated, namely, higher requirements are put on the stiffness-to-weight ratio.
