(2) There are several key parameters in IMPACT function as followed: (1)Stiffness K:material stiffness (to calculate the vertical force of the contact-impact model),its value depends on the impactor material and structural shapes
(2)The damping properties of contact materials
In this paper, two gears material is both used as 45 steel(U=0.3，E1=E2=2.1e+11Pa).The gear contact parameters calculated based on references are listed in Table 2.
