摘　　要：对全新布置的高能管道系统进行力学分析时,初始布置管道的力学分析结果往往不能满足规范和相关规定的要求,需对管道系统的布置(管道走向、支承位置和功能)进行调整。力学分析结果满足要求后,还需确认管道布置所需的空间是否可行,为得到相对合理的管道布置方案,需反复进行调整和协调。介绍一种尽可能减少管道调整和协调次数的优化分析方法,并以实例介绍该方法的应用过程。通过对实例的力学分析,详细讲述高能管道的力学分析过程、特殊应力指数的计算方法和计算结果评定。结果表明,该优化分析方法可提高管道系统布置优化的效率,是一种实用有效的方法。The mechanical analysis results usually cannot match the requirement of criterion or specification for new layout high-energy piping system. Then the design of the piping system or the location or function of supports on the piping should be improved until requirements of criterion and specification are matched. Then the space should be checked to insure that the piping and its supports can be laid down. Repeat improvement and harmonization are needed in order to find a satisfying piping layout. An optimization analysis method which can reduce the number of improvement and harmonization is introduced in this paper. This method is used in a new high-energy piping system mechanical analysis. The process of high-energy piping mechanical analysis, the method for special stress indices calculation and the evaluation of analysis results are also introduced in this paper. The results show that the optimization analysis method is an effective and practical method used for new high energy piping system analysis.
