DYNAMIC CHARACTERISTIC ADJUSTABLE MACRO-MICRO INTEGRATED COMPOSITE PLATFORM

摘要

A dynamic characteristic adjustable macro-micro integrated composite platform. When macro and micro platform rotors are simultaneously driven, overall large-range high-speed movement can be realized. When the movement deviates, a micro-motion platform realizes precision displacement output by means of elastic deformation due to small inertia and no friction, and high-frequency movement deviation compensation can be realized by means of individual driving. High-speed precision movement can be realized by means of composite movement control, a mounting usage mode is consistent with a traditional platform mode, and is convenient to promote and apply. Meanwhile, the platform is provided with rigidity and frequency adjusting mechanisms and a variable damper, such that the micro-motion platform can transmit the movement of a macro-motion platform under any frequency, the vibration is isolated, and high-precision displacement compensation is realized. Meanwhile, the damping magnitude of the variable damper matches rigidity frequency parameters, high-precision displacement compensation under any frequency is guaranteed, and the work frequency range is expanded.
