【Abstract】 The method is proposed for sensitivity of dynamic behavior of a helical gear pair The dynamics model of the helical geared system accounts for the shaft and bearing flexibility, the dynamic coupling among the transverse, torsional, axial and rotational(rocking) motions due to the gear mesh The formulas of sensitivities of natural frequencies and dynamic teeth flexibility are derived with respect to supporting structural parameters of a helical gear pair An example is given to illustrate the procedure The method proposed is of practical importance in the optimization design or modification of helical geared systems更多还原
