Abstract:
1. A computer-implemented method for estimating a conditional indicator value associated with a gear pair comprising: modeling said gear pair as a damped spring model having a contact line between said gears; determining a force, P, at a point of contact along said contact line causing linear and torsional response to each of said two gears in said gear pair; determining a relative movement, d, of said gear pair, in accordance with said force, P, as a sum of four responses and a contact deflection, said relative movement d representing a gear model having two degrees of freedom, said contact deflection being due to a contact stiffness of a contact patch where two gears of said gear pair come into contact, and a linear damping coefficient of the contact patch; and using said relative movement, d, in determining said conditional indicator value for transmission error associated with said gear pair.
