摘要
提出一种以能量法为理论基础、基于ANSYS平台的转动突然制动对天线结构强度影响的仿真分析方法,方便、实用,尤其适合复杂结构系统的工程应用。以某120 m大口径天线俯仰转动部分为实例,详细介绍俯仰转动突然制动对天线结构强度影响的仿真分析过程。该方法为分析转动突然制动对天线结构强度的影响提供了一种新思路,并对天线的研制具有重要的指导意义。
This paper puts forward a simulation analysis method of the influence of sudden rotation braking on the strength of antenna structure based on the energy method and ANSYS platform,which is convenient and practical,especially suitable for the engineering application of complex structural systems.Taking the pitching rotation part of a 120 m large aperture antenna as an example,the simulation analysis process of the influence of sudden rotation braking on the structural strength of antenna is introduced in detail.This method provides a new idea for analyzing the influence of sudden rotation braking on the strength of antenna structure,and has important guiding significance for the development of the antenna.
