计算机力学仿真在弹载模块结构设计中的应用
|
摘要
在火箭发射过程中弹载电子设备会承受高强度的变频率随机载荷、冲击载荷及加速度载荷,对于难以开展实际试验的弹载电子设备,进行结构设计时,借助计算机结构力学仿真结果,在相应载荷工况下得到的仿真数据和可视化后处理图像,可对弹载结构件所受应力及变形情况等进行力学和变形分析,从而达到快速完成结构设计、优化达到设计合理的目的,更好地控制科研成本和周期。
In the process of rocket launching, missile-borne electronic equipment will be subject to strong frequency-variable random load, impact load and acceleration load. For the missile-borne electronic equipment which is difficult to be tested in actual experiments, the mechanical and deformation analysis of the missile-borne structural components can be carried out by means of the computer structural mechanics simulation, i.e. using the simulation data and the visualized post-processing images obtained under the corresponding load conditions, so as to achieve rapid structural design, structural optimization, reasonable structural design and verification, to better control the cost and cycle of scientific research.
