摘要
安全阀试验容器是安全阀型式试验系统的重要设备,其长周期安全运行是安全阀质量体系的有力保证。通过弹塑性方法,结合关联流动法则,考虑多种失效模式,对一台高压球形试验容器展开强度和疲劳分析,可针对结构应力-应变进行全过程计算。分析结果显示,弹塑性方法对于安全阀试验容器具有良好的分析效用,可提高安全阀型式试验的准确性和高效性,分析过程可作为相似设备的工程参考。
Safety valve testing vessel is a important equipment of the safety valve type test system,its safety operation of long term provides strong guarantee to the safety valve quality system.Through elastic-plastic method,combining associated flow rule,considering multiple failure modes,analyse of strength and fatigue to a high-pressure sphere testing vessel is launched,all process calculation of structure stress-strain could be operated.According to analysis result,elastic-plastic method performs excellent analysis effect on the safety valve testing vessel,additionally,it helps increasing the accuracy and high efficiency of safety valve type test,the analysis process can be a engineering reference of similar equipment.
