Conventionally, when predicting motorcycle vibration using the data from drawings, connector characteristics for the components were uncertain. Therefore, using test pieces, we tested bolt fastening connector characteristics in order to investigate a potential analysis method. Further, a detailed FEM model was created, and the contact domain of connectors was calculated using the nonlinear-GAP static analysis of MSC/NASTRAN. Normal mode analysis was performed by converting the domain into a high rigidity spring element, and it was verified that the resonance frequencies for each mode were generally the same. By applying this method to an actual motorcycle and by also applying NASTRAN’s RESVEC calculation to connectors of a component, the FEM model was improved.
