Predicting the effects of housing flexibility and bearing stiffness on gear misalignment and transmission noise using a fully coupled non-linear hyperstatic analysis

摘要

The paper describes a numerical simulation method to predict efficiently and accurately how changes to a transmission's housing can affect gear mesh misalignments. A fully coupled non-linear algorithm to analyse the shaft/bearing/gear/housing hyperstatic system has been developed. A reduced stiffness matrix (which can be creasted by created by most commercial FEA packages) is used to efficiently model the housing.
