机械设备失效形式分析与对策

Analysis and Countermeasures of Mechanical Equipment Failure Mode

机械设备失效多由于存在原始缺陷或损伤造成的裂纹萌生,裂隙扩展导致的,同时也受环境条件的改变、机械设备所承受载荷、温度及介质环境等影响。为此判断机械设备失效的性质、分析机械设备失效的原因、研究解决问题的对策将具有重要的经济和社会意义。

The machinery and equipment failures than the original because of defects or damage caused by crack initiation, cracks caused by expansion; the same time, changes in env＇ironmental conditions, mechanical equipment under load, temperature and medium environmental impact. To this end, determine the nature of mechanical equipment failure, equipment failure analysis of mechanical reasons, the study of solutions to this problem will have important economic and social significance.
