METHOD FOR EFFECT AND FEASIBILITY ANALYSIS OF THE SMOOTHING FUNCTION FOR CLEARANCE-TYPE NONLINEARITY IN A PRACTICAL DRIVELINE SYSTEM

摘要

The present invention develops a new concept of a smoothing function and applies it to a real-vehicle system model to improve the utility and applicability of the smoothing function in the analysis so that the response characteristics of the system to the gear shock phenomenon including the basic superharmonic element can be analyzed The present invention relates to a new concept of smoothness function and efficiency analysis method for a nonlinear analysis of a gap type in a real vehicle drive line system, using a smoothing function model using an nth order polynomial function; The smoothed function coefficient ( ), Which is a key element of the smoothed function model,₂); And examining the influence of the simulation using the smoothing function model based on the harmonic balance method (HBM) by focusing on the gear impact condition. In the nonlinear analysis of the gap type in the actual vehicle drive line system, It is effective to provide a smoothing function model with few errors.
