Research on Coupling Dynamics of Certain Type Launch Platform with Turning and Pitching in Level 6 Sea State

针对某型靶弹通用发射平台,开展该平台在摇摆载荷作用下的回转和俯仰耦合动力学特性的研究。将原有陆基发射平台的回转俯仰耦合动力学扩展到海上平台,分析其在某型船6级海况下的运动特性和回转俯仰耦合动力学特性;将6级海况等效为沿3坐标系的等效加速度,基于ADAMS对该海况下的靶弹通用发射平台进行仿真分析。仿真结果表明,该研究对复杂海况下发射平台的结构强度和运动规律均具有一定的指导意义。

Aiming at the general launching platform of a certain type of target missile, the coupling dynamic characteristics of rotation and pitch of the platform under the action of swing load are studied. The coupling dynamics of rotation and pitching of the original land-based launch platform was extended to the sea platform, and the motion characteristics and coupling dynamics of rotation and pitching of the launch platform were analyzed under the 6-level sea state of a ship. The 6-level sea state was equivalent to the equivalent acceleration along the 3-coordinate system, and the simulation analysis of the target missile general launch platform under the sea state was carried out based on ADAMS. The simulation results show that the study has certain guiding significance for the structural strength and motion law of the launch platform under complex sea conditions.
