摘要：

Finite element analyses are presented of temperature distribution and thermal deformation of workpieces including a cylinder, an engine cylinder with cooling fins, and a connecting rod are studied. The heat quantity flowing into the workpiece is about 98% of the heat generated during honing. In a cylindrical workpiece, radial thermal deformation at the honing surface is closely estimated by the product of the temperature increase at the outer surface, the coefficient of thermal expansion, and the radius at the honing surface. For the engine cylinder thermal deformation affects the dimensional and geometrical accuracy, and the effect on cylindricity is about 30% of the effect on the radius. For the connecting rod, thermal deformation affects only dimensional accuracy, and the effect of roundness is 5% of the effect on the radius.
