A Method of Parametric Stability Region Determination for Non-linear Gear Transmission System
A general method of parametric stability region calculation for a non-linear transvers-torsional coupled gear trains vibration model with multiple-clearances is studied.There are six steps in the method,and the first step is strength and fatigue life threshold determination,and the second step was deciding numerical integration time according to the motion state of the system when the parameters discussed changed in their test range,the third step is calculating the maximum displacement of the system when the parameters discussed changed in their range by using nested loop algorithm,the forth step is calculating the value which equals the maximum displacement subtracted by minimum displacement by the same method with third step,the fifth step is the stability judgment by comparing the value which is calculated in step four and five with threshold which is set in second step,and the last step is make the parametric stability region map of the system.As an example,the stability region calculation of a coupling transverse-torsional gear train vibration model with multiple-clearances is studied under the parameter of the backlash,mesh damp ratio,input rotation speed and the bearing clearance of the driving wheel and driven wheel,and the stable region of input rotation speed,backlash,meshing damp ratio and the bearing clearances are calculated respectively.
