Dynamic Properties of Machine Bolted Joints Summary

There are a lot of connection forms between the machine parts, of which the most typical are bolted joints. There are many factors influencing the dynamic properties of bolted joints and their mechanism is very complicated. Their properties have great significance to machine accuracy prediction. Domestic and overseas scholars have conducted many extensive researches on bolted joints, which main influence factors and internal mechanism are clarified. There is a more in-depth research on the analytical solution and the parameter identification of dynamic properties of bolted joints, and has achieved certain results, but the researches on mechanical properties are not mature. This article bases on microscopic analysis, macroscopic modeling, macroscopic test, nonlinear problems to classify research results, analyze the deficiencies, and point out the future research trend.
