摘　　要：以连续无篮杀菌生产线上的立式杀菌锅为研究对象,在考虑温度、水压等情况下,分析有裂纹杀菌锅的力学特性;并将裂纹设置为随机变量,采用随机有限元法分析各影响因素对杀菌锅可靠性的影响。先采用SolidWorks建几何模型,再运用有限元软件Ansys计算,分析其力学特性和可靠性。结果表明:温度相对水压力来说对杀菌锅力学特性影响大;在有裂纹的情况下,应力和位移受裂纹深度影响较大;根据Ansys中的拉丁超立方法分析得出杀菌锅可靠度为96.7%。Taking the vertical retort on a continuous basket-less sterilization production line as the research object,analyzed the cracked retort considering the temperature and water pressure.At the same time,the cracks were set as a random variable and the influence factors on the reliability of the retort were analyzed by the random finite element method.Firstly,the geometric model was built by SolidWorks,then the mechanical properties and reliability were calculated by ANSYS.The results showed that:compared with the water pressure,the temperature had a great influence on the mechanical properties of the retort.To the cracked retort,the crack depths greatly affected the stress and displacement.According to the Latin superposition method in ANSYS,the reliability degree of the retort can reach 96.7%.
