摘要
目的：研究某弹药储运方舱支撑件的力学特性。方法采用SolidWorks软件建立三维模型,利用ANSYS Workbench软件进行静力学和动力学的仿真分析。结果仿真结果显示,该支撑件在静力学中所受的最大应力值为2633.7 Pa,最大变形量为5.6847×10^-5 m,动力学中振动形式有弯曲振动和扭曲振动,前6阶的固有频率在117.5~286.7 Hz之间。结论研究表明,该支撑件满足结构的刚强度要求,并为下一步进行瞬态动力学分析、随机振动分析奠定了基础。
Objective To study the mechanics characteristics of the support in an ammunition storage and transportation shelter. Methods This article adopted the Solid Works software to establish the three-dimensional model, and simulative an-alyses of statics and dynamics were carried out using the ANSYS Workbench software. Results The result of simulation in-dicated that the biggest stress and deformation of the support subjected in statics were 2633. 7 Pa and 5. 6847×10^-5 m, re-spectively;and the vibration modes in dynamics were bending vibration and twisted vibration. The preceding 6 ordered in-herent frequencies were in the range of 117. 5~286. 7 Hz. Conclusion The research indicated that this support satisfied the rigid strength demand of the structure, and laid a foundation for the transient dynamics analysis and random vibration a-nalysis.
