Feature Based Parametric Design of Piston Reliability

In this paper the characteristics of the piston features for classification and feature library; at the same time the feature size and the feature existence parametric methods are discussed in detail. In a detailed analysis of the engine piston load based on, forward piston mechanical,thermal boundary conditions, forward piston mechanical, thermal boundary conditions, the results show that the original piston has a larger reserve strength, this research provided probility for the further optimization.
