On Piston Rod System Operation Analysis and Piston Structure Optimization Research

The transmission components of internal combustion engine power are piston rod structure. The quality of the structure design has direct impact on the whole machine. Alternating thermal load and mechanical load are pistons, which are under the worst piston rod system working condition. This article performs operation analysis piston rod structure through the corresponding application of Pro/Mechanica and Pro/Mechanism, so that the stress and piston dangerous stress concentration location shall be determined based on piston structure optimization design. This way leads to quality improvement of piston rod structure design, leading to extended products service life, which has a particularly important role and significance.
