摘要
为了提高舰载多管火箭的射击密集度,该文应用多体系统传递矩阵法和独立模态空间控制方法,研究舰载多管火箭系统的振动特性和振动控制,建立了某舰载多管火箭系统动力学模型,固有振动特性数值计算和振动控制方法,具有无需建立系统总体动力学方程、涉及系统矩阵阶次、计算速度快等特点。实现了对舰载多管火箭刚柔耦合多体系统不同装载情况下固有振动特性的快速计算和振动控制,数值计算结果得到了模态试验的验证。对控制舰载多管火箭发射系统振动、提高舰载多管火箭射击密集度具有重要意义。
In order to improve the firing dispersion of the Shipborn Multiple Launch Rocket Systems（ SMLRS）,the vibration characteristics and vibration control of the SMLRS are studied using the transfer matrix method for multibody system and independent modal space control method. The dynamic modal of a SMLRS and the method for numerical calculation and control of vibration performance of the system are developed. The features of this method are as follows,without the global dynamics equations of system,high programming,low order of matrix involved and high computational speed. The rapid calculation and vibration control of the dynamic properties of a SMLRS under various loading conditions is realized and the numerical results are verified by the modal test. The propositional method is important to control vibration to improve firing dispersion of SMLRS.
