| Popis: | 104 This proposal presents an adaptive vehicle rotate angle system using dual micro-inertial sensor, which can apply to underwater environment. The system consists of vehicle rotate angle estimation module and PZT driving module to form adaptive front LED lighting system. Driving module is composed of two core components: symmetrical piezoelectric element and trussed preload structure. The design of the symmetrical piezoelectric element is utilizing the finite element analysis to simulate its motion characteristics, in order to get the fixed point and the driving point. The piezoelectric actuator of the preload structure design improves the general linear preload track type into torque track type, to further simplify the linear preload track into rotation track and introduce the truss structure component concept to ameliorate preload skew problem, and design a triangular truss-type preload mechanism, and then to integrate with SPE as a driving module. Finally realizing the active dynamic feedback sensing concept and enhance AUV or ROV in underwater exploration technology capability. |
