【摘要】：本文在介绍了超高压容器的概况，特别就厚壁圆筒自增强处理为本论文出发点，，基于弹塑性力学理论较为系统地阐述了理想弹塑性材料模型的自增强厚壁圆筒的应力分析，分别得到各应力分量与等效应力的解析解，就科发有限公司的高压灭菌设备为例，分别对此产品做优化分析和ASME疲劳认证，使此高压灭菌设备高效安全的工作。通过对厚壁圆筒的理论分析得到的解析解，解析解中的各个参数是基于科发有限公司高压灭菌设备的实际参数，结合Matlab绘制出得到应力分量的解析解，与有限元软件ANSYS分析仿真模拟得到的各应力分量的路径图对比，确认模拟解的可靠性，为本论文后续分析做好基础。有限元软件ANSYS对高压灭菌设备的承压筒体建模分析，在前处理过程中就对承压筒体进行自增强处理，施加工作载荷，得到工作状态下的承压筒体的模拟情况。在后处理的过程中以高压灭菌设备的在工作状态下的应力分布最佳和等效应力最低为目标，寻求最优的自增强压力，使承压筒体更加高效的工作。基于ASME疲劳认证标准，通过ANSYS对高压灭菌筒体在工作状态下的应力分析得到疲劳认证所需要的数据，结合ASME疲劳认证这方面的相关规范，进行评定，得到是否疲劳的评定，以确定科发公司高压灭菌设备安全的工作。
[Abstract]:In this paper, the general situation of ultra-high pressure vessel is introduced, especially the self-reinforcing treatment of thick-walled cylinder is the starting point of this paper. Based on the theory of elastic-plastic mechanics, the stress analysis of the self-reinforced thick-walled cylinder in the ideal elastic-plastic material model is systematically described, and the analytical solutions of each stress component and the equivalent stress are obtained respectively. Taking the high-pressure sterilizing equipment of Kefa Co., Ltd as an example, the optimization analysis and ASME fatigue certification of this product are made to make the high-pressure sterilizing equipment efficient and safe. Through the theoretical analysis of the thick wall cylinder, the analytical solution is based on the actual parameters of high-pressure sterilizing equipment of Kefa Co., Ltd. The analytical solution of the stress component is drawn with Matlab, and compared with the path diagram of each stress component obtained by the finite element software ANSYS simulation, the reliability of the simulation solution is confirmed. This paper provides a good basis for the follow-up analysis. The finite element software ANSYS is used to model and analyze the pressurized cylinder of high pressure sterilizing equipment. In the process of preprocessing, the pressure cylinder is treated with self-reinforcement and the working load is applied. In the process of post-processing, the optimal stress distribution and the minimum equivalent stress of the high-pressure sterilizing equipment in the working state are taken as the goal to seek the optimal self-reinforcing pressure. Make the pressure cylinder more efficient work. Based on the ASME fatigue authentication standard, the data needed for fatigue certification are obtained through the stress analysis of the high pressure sterilizing cylinder under the working condition by ANSYS. According to the ASME fatigue certification criterion, this paper evaluates whether the fatigue is fatigue or not, in order to determine the safety of high-pressure sterilizing equipment in Kefa Company.
