在工程机械中承受内压力及外载力的岔管是普遍存在的,这类结构往往是工业设备的关键部件,例如水电站的引水岔管、核电站反应堆、化学设备中管接头、锅炉和船舶设备中各种管接头、输油管道等。由于实际受力复杂、分析困难,设计难度也大。为解决这一困扰人们的难题,上海计算所经过几 Bifurcation pipes that are subject to internal pressure and external forces in construction machinery are ubiquitous. Such structures are often the key components of industrial equipment such as diversion bifurcations for hydropower stations, reactors for nuclear power plants, pipe joints for chemical plants, boilers and marine equipment In a variety of pipe joints, pipelines and so on. Due to the actual force complex, difficult to analyze, the design is also difficult. In order to solve this troubling people’s problems, how many times has Shanghai calculated?
