【Abstract】 Force acting at piston skirt from hydrodynamic fluid film and moment about piston pin were obtained from Reynolds equation of hydrodynamic lubrication. Equations for piston skirt motion together with expressions for film force and moment constituted equations for piton movement. A useful method of solution was obtained. Calculation results showed that the effect of piston skirt parameters on lubrication characteristics is significant.更多还原
