Application of Simulation Technology in Environmental Suitability Analysis of Depth Charge Launcher

摘要:

深弹发射装置安装在甲板部位,使用环境恶劣,过去均采用传统的试验方法进行环境适应性考核。最近几年,随着三维设计的广泛应用,仿真技术也开始发挥作用,以发射装置接线箱的冲击响应为例，介绍仿真技术在发射装置环境适应性分析中的应用。通过案例分析可知,仿真分析对于发现机械结构设计中的薄弱环节还是非常有效的,它突破了环境试验受限于试验样机和特定环境条件的限制,可以在较短的时间内得到仿真结果,对装备模型进行及时修正。

Abstract:

The depth charge launcher is installed on the deck section and the operation environment is very tough. In the past, the traditional test method was used to assess the environmental suitability. In recent years, with the wide application of three-dimensional design ,, simulation technology has also started to play a role. In this paper, the impulse response of the junction box ofthe launcher is taken as an example to introduce the application of simulation technology in the environment suitability analysis of thelauncher. The case analysis shows that the simulation analysis is very effective in finding the weak links in the design of mechanicalstructures, and it breaks the limitation of environmental test, including the experimental prototype and the specific environmentalconditions. The simulation results can be obtained in a relatively short period of time, and the equipment model is corrected in time.
