This study examines the influence of some dimensional errors on the shudder-type disturbance of the tripod joint and vehicle, using an experimental evaluation and related simulation. With the introduction of the concept of influence factor, the sensitivities of shudder-type disturbance can be evaluated as the ratio of the difference between the ideal value without dimensional errors and actual value with them in the tripod joint and vehicle. Futhermore, influence factors calculated in this study can be utilized as a basic design data for the practical application of the tripod joint to an automobile design.
