Stress Analysis in a Con-Rod Using Oil Film Pressure in a Bearing Calculated with Elasto-Hydrodynamic Lubrication

弾性流体潤滑計算による軸受油膜圧力を利用した コンロッドの応力解析

A compliance matrix, which expresses the relation between bearing deformation and oil film pressure, is used in an elasto-hydrodynamic lubrication, EHL. The compliance matrix is derived with a structural analysis of a con-rod using design data of a 3D-CAD. Force distributions on the boundary of the con-rod are obtained from the oil film pressure on the bearing surface calculated with the EHL. Stress analysis is performed using the structural analysis in the 3D-CAD and the stress distributions in the con-rod are clarified over an engine cycle. The results under low and high engine speeds are shown in comparison with each other. Finally, the effect of engine speed on the stress distribution and the maximum stress is discussed.EHLで用いる軸受の変形と油膜圧力の関係を表すマトリックスを3次元CADの構造解析機能を利用して求めた. 軸受面の境界条件としての力の分布をEHLの油膜圧力から求め,これを用いてエンジンサイクルでのコンロッドの応力分布を3 次元CAD の構造解析で求めた.高速と低速の結果を比較した.
