The torpedo cylindrical cam motor with inclining rollers was studied.

Operating conditions of cam and roller tribo-pair has important influence on the operation of the torpedo cylindrical cam motor with inclining rollers.

Based on the virtual prototype technology and 3-dimension modeling software UG,the correlatively parameterized modeling and assembling for torpedo cam engine are developed using the top-down design idea to transmit the key parameters modified in the top control system to the detailed parts,thus to update the assembled model with the correlative parameters.

In order to further study the operational mechanism of torpedo cam engine with inclining rollers, this paper presents a method of calculating the parameters of the contact point between the cam and the roller, and preliminarily analyses the loading condition between the roller and the cam.

To evaluate the performance of cam engine with the counter-position placement,such a thermodynamic model based on the kinematic and dynamic analysis is developed and the corresponding program with the Runge-Kutta method is established.
