The main stages of studying modern high performance engine connecting rod strength and reliability are shown. The study includes combining and analysis of calculation and experimental results.  The hierarchical system of mathematical models for structural analysis and cyclic strength estimation of connecting rods has been considered. The rationality of combining macro-element method (used at the first stage) with three-dimensional finite-element analysis used at the final stage is shown.

This article contains some results of thermal state modeling of multi-piece mid-speed diesel piston, considering features of contact interaction between piston parts.
