通过对拖曳天线运动状态及其受力进行分析,建立了其动力学模型;针对模型复杂的非线性和耦合性,在考虑天线旋转平衡时构型的基础上,采用Galerkin法研究求解了其末端锥袋的非线性振动。通过仿真并对多阶Galerkin方法截断求解结果进行比较,验证了Galerkin方法求解时的收敛性和可靠性。仿真结果表明,在无风条件下,拖曳天线的末端锥袋振动不会对机载甚低频通信系统的通信质量产生明显的影响。
Based on the analysis of the moving state of the towed antenna and its force, the dynamic model of the towed antenna is established. Based on the complicated nonlinearity and coupling of the model, the Galerkin method is used to study the configuration of the antenna when the rotation equilibrium is considered. Nonlinear vibration of cone bag. The simulation results show that the Galerkin method solves the convergence and the reliability of the solution. The simulation results show that the vibration of the terminal cone of towed antenna will not affect the communication quality of the airborne very low frequency communication system obviously under no wind condition.
