一种低散射金属支架的运动学计算及仿真

Kinematic Calculation and Simulation of a Low Scattering Metal Pylon

低散射金属支架是隐身武器研制过程中的重要装备,主要用于电磁散射测量中的目标支撑。在紧缩场中对待测目标进行RCS测量时,目标定位结构形式及支架整体刚度性能非常重要。本文对橄榄形截面金属支架结构特点进行了分析,并计算了空间转轴位置参数。在200 kg载荷下进行力学分析,借助ADAMS对运动特性进行了仿真分析,得到了运动关系曲线,为此类金属支架原动装置的设计制造提供有效的参考依据。

A low scattering metal pylon, mainly used for target supporting in electromagnetic scattering measurement, is important to design and manufacture stealth weapons. The target positioning structure and overall stiffness of the pylon are very important when the RCS measurement is carried out in the compact range. This paper analyzed the structural characteristics of an oval metal pylon and calculated position parameters of the space rotating shaft. We obtained the curve of motion by mechanical analyses under a 200 Kg load and a kinematic simulation using ADAMS, and the curve provides an effective reference for the design and manufacture of driving devices of such metal pylons.
