分析柴油机关键性零部件强度和刚度的方法的总发展趋势,是力图较完整和精确地考虑其几何形状和实际的负荷条件。在这种情况下,在现代的弹性理论计算方法中,可以使用同一数学方法,以最大的可靠性确定零件的应力变形状态。有限元法和它的变态——超级元法已被越来越广泛地采用。在对给定几何形状的零件进行数值计算 The general trend in the way of analyzing the strength and stiffness of diesel critical components is to try to consider their geometry and actual load conditions more fully and accurately. In this case, the same mathematic method can be used to determine the stress-strain state of a part with maximum reliability in the modern elastic theory calculation method. The finite element method and its metamorphosis - super-element method has been more and more widely used. The numerical calculation of the part for a given geometry
