Abstract

Parts of assembly are mainly fixed and connected by bolts. The performance of the assembly can be affected by the dynamic characteristics of the bolted joints. Report focuses on designing a test bench by parameter analysis and achieving the dynamic analysis of the bolted joint. In the first part, the eigenfrequency of a simple single beam with different size parameters are analyzed with NASTRAN and the complex model of the bolted joint are analyzed. After that the effects of different parameters on the eigenfrequency are obtained and a bolted joint test bench is designed with CATIA. In the second part, a model specimen is made. The material of bolts is changed to compare the dynamic response with different preloads using Polytec Scanning Vibrometer. At last, the comparisons between experimental results and numerical simulation are obtained.
