Stable Floating Platform For A Weapon System Dynamics Analysis

In this paper,taking a weapon system as the research object. With the aid of virtual prototype technology, the swaying motion of the weapon system in the sea, the operative mode of the aiming system and the leveling system are researched respectively. Additionally, in the state of launching, launcher's initial disturbances caused by sea wave and the key structure's reliability are studied. In the end, obtaining some important datebase for engineering analysis.Firstly, based on the performance of the weapon system, designing each subsystem structure and a three-dimensional model. According to the behavior theory of ship movement, establishing the movement equation of floating platform and simulating the platform movement by multi-body fluid dynamics analysis software-AQWA in different sea wave, which provides displacement driving data for the next dynamics analysis. Secondly, establishing multi-rigid-body dynamic model of the aiming system and the leveling system, simulating the properties of power system in the process of aiming and leveling under different sea wave. Thirdly, based on analytical mechanics method, setting up launching dynamics model, simulating launching dynamic properties, analyzing launcher's initial disturbance under the different sea wave and different shooting angle. Finally, the rigid-flexible coupling dynamic model was accomplished by uniting ADAMS and ANSYS, acquiring the stress and strain of the key part at each time which are used to evaluate the reliability of the part.This paper conclusion provides certain theoretical basis for structure optimization and engineering experimental study, the analytic method provides guidance for further research.
