摘要
深海高压模拟装置对深海技术的发展以及对海洋科学的深入研究具有重要的推动作用。以深海高压模拟装置的核心部件─压力筒为研究对象,对其进行了动态响应分析。计算出球壳在加压破坏后筒体内部压力的数据,借助ANSYS有限元分析软件,利用控制变量法对压力筒整体进行了瞬态动力学仿真。通过对有限元仿真结果的分析比较,得到了压力筒的应力分布状况,验证了压力筒的强度满足设计要求。上述的研究结果与方法,为压力筒内部球壳爆破时的状态提供了一种可行性分析方法,也为高压设备的设计和改造提供了一定的理论数值参考。
The high pressure testing equipment for the environment simulation of deep-sea plays an important role in the development of deep-sea technology and in-depth study of marine science. The dynamic response of the pressure vessel,the core component of the deep-sea high-pressure simulator,is analyzed. The internal pressure data of the spherical shell after pressure failure are calculated. The transient dynamic simulation of the whole pressure cylinder is carried out by using ANSYS and the control variable method. Through the analysis and comparison of the finite element simulation results,the stress distribution of the pressure cylinder is obtained,which verifies that the strength of the pressure cylinder meets the design requirements. The above results and methods provide a feasible analysis method for the state of spherical shell blasting in pressure cylinder,and also provide a theoretical and numerical reference for the design and renovation of high pressure equipment.
