| 摘 要： | 偏转弹头控制是一种新型的快速响应控制技术.为了提高偏转机构设计的效率和可靠性,对一种斜盘式偏转机构初始设计方案进行了研究:通过坐标转换推导出弹头偏转规律;基于多体系统动力学理论,在ADAMS中建立了该机构的虚拟样机,采用修正的Newton-Paphson迭代算法,仿真研究了机构的静态特性;通过ADAMS与SIMULINK联合,采用Runge-Kutta算法,仿真研究了机构在阶跃信号作用下的动态特性,确定了关键设计参数.仿真结果表明:弹头偏转角只与电机角位移有关;机构方案具有精度高、响应速度快等优点.

| Abstract: | Deflectable nose control is a new fast response control method. In order to improve the efficiency and reliability of the design of nose deflecting mechanism, a kind of initial rolling sloping plat design scheme is selected and the control scheme is deducted through coordinate transformations. According to Multi Body Dynamic theory, the static characteristics of this mechanism are studied by under Modified Newton-Paphson iterative method through simulating its virtual prototype built in ADAMS. The dynamic c... |
