The Method of Stress State Analysis in the Crank Plane between the Necks of the Crankshaft
The method of stress state analysis in the section of crankshaft crank located at the top and bottom dead points of the piston stroke, without considering additional cavities in journals (except for an oil channel) is proposed. The problem of the determining stress state in the crankshaft journal overlapping in an elastoplastic statement with considering large displacements is solved for the first time. A parametric crankshaft crank model taking into account all the geometric features of its design (including an oil channel) is built. The oil channel position considered as an example is characteristic of the first and last crankshaft cranks. Methodological comments to the proposed models based on use of ANSYS 10 ED are given. It allows engineering and design staff to understand the model, refine it in accordance with the drawings and perform optimization of the geometric parameters of the crankshaft by the durability criterion.
