多缸发动机的曲轴在连杆所传递的力的作用下会产生空间变形,这些空间变形由扭曲、拉伸—压缩和弯曲所组成,并与整个发动机机体主轴承的变形是相互关联的。轴承部件和曲轴的破坏,要求对它们共同的应力—变形状态进行更周密的研究。在分析曲轴—机座系统原始结构时,作者建立了该系统三维变形状态的四阶结构计算图。近似于一些棱形体积有限元的12ДРН23/30柴油机模型的数值计算,可以获得曲轴和
Crankshafts of multi-cylinder engines produce a spatial deformation under the force transmitted by the connecting rod, which is composed of twisting, stretching-compressing and bending and is interdependent with the deformation of the main bearing of the entire engine body. Destruction of bearing components and crankshafts requires more careful study of their common stress-strain conditions. When analyzing the original structure of the crankshaft-base system, the author established the fourth-order structural calculation diagram of the three-dimensional deformation state of the system. The numerical calculation of a 12ДРН23 / 30 diesel engine model approximating some prismatic volume finite element gives crankshaft and
