机械松动现象与故障特性研究综述
Review of Mechanical Looseness Phenomena and Failure Characteristics Study
摘要
Abstract
There exist looseness phenomena in mechanical systems, including foundation looseness, pedestal looseness and component match looseness. The causes of the three types of looseness were explained with examples. Some common types of looseness models were summarized. Research status of six types of looseness, including single looseness, looseness coupled with rub-impact, looseness coupled with crack, looseness at two end-supports, looseness of rotor system with slowly varying mass, and looseness of double-span rotor system was elaborated in the aspects of dynamics modeling, solution meth-od and their nonlinear dynamic characteristics. Research of looseness experiments were also introduced briefly. Finally, the hot points for further study of the looseness faults were prospected.关键词
