| 摘 要： | 分析了疲劳试验系统中存在的普遍问题,即试验载中峰值和均值随着试验时间和试件的机械性能变化而发生漂移。这一现象将直接影响试验精度和对试件质量的评估。由于试个本身参数很难确定,尤其是当试件接近疲劳寿命时,为此,以往都是人工进行调整。采用了模糊控制技术后,将试验人员的经验用一定的算法表示出来,从而实现了对试验载荷的自动跟踪,较好地解决了上述问题。

| Abstract: | The generalproblem in the fatigue test system that the amplitude and mean of load signal will bechanged with test time and change of mechanical characters of specimens is analyzed.Thisproblem will directly effect on the test-accuracy and evaluation of specimen's quality.Inthe past,parameters of test system must be manually adjusted because it is very difficultto determine those parameters, especially when specimen approaches its fatigue life.Afterusing fuzzy control,the experience of the test engineer can be expressed with mathematicalformulas.Therefore test load will be automatically adjusted. The problem has been wellresolved. |
