对某发动机低压涡轮盘进行了技术寿命研究。对盘进行了应力计算、寿命分析 ,确定了考核部位。介绍了试验设备、试验件及试验参数。给出了两个试验件的试验结果 ,并根据有关规范给出了轮盘的标准循环数和平均飞行小时数。试验研究为轮盘定寿、延寿提供了试验依据。
The technical life of a low pressure turbine disk was studied. The disk was stress calculation, life analysis, to determine the examination site. Introduced the test equipment, test pieces and test parameters. The test results of two test pieces are given and the standard number of cycles and the average flight hours of the roulette wheel are given according to relevant regulations. The experimental study provides the test basis for the roulette life-span and life extension.
