摘要
在民用飞机结构适航符合性验证试验中,全机结构疲劳试验是最复杂、最昂贵、最耗时的,提高全机疲劳试验效率、缩短全机疲劳试验周期一直是型号研制中追求的目标,尤其是疲劳试验管理技术的提高。在MA600,ARJ21-700,Y12F等全机疲劳试验中引入并行实验管理技术进行工程应用,提出应用并行试验管理技术应当注意的问题。结果表明:并行实验管理技术在全机疲劳试验时缩短了试验时间,提高了试验效率,发挥了重要作用。
Full aircraft structure fatigue test, as a part of civil aircraft structure airworthiness verification test, is the most complicated, the most expensive and the most time-consuming. Improving the efficiency of full aircraft structure fatigue test and shortening the fatigue test cycle have always been pursued, especially for fatigue test management technique. This paper introduces concurrent engineering which is applied to full aircraft fatigue tests such as MA600, ARJ21-700, Y12F tests. The traditional serial working mode is transformed into the parallel working mode. Concurrent test management technique is summarized and proposed creatively. The basic content and method of concurrent test management technique are described. Different requirements of the technique in different stages in a single test are analyzed. At the same time the management methods in multiple tests in the same factory are proposed. The practice shows that concurrent test management technique plays an important role in accelerating the cycle of full aircraft fatigue test. What's more the technique is potential for further research and it is of application prospects.
