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.
