一种曲轴的设计,受到时间的限制,往往达不到最优化的要求。用经验的方法和应力集中的方法,由于一些未知因素的影响,设计一定会偏于保守。用反复试验法在短期内又得不到所需的数据。这样,不仅曲轴,而且包括整个发动机在内,设计的非最优化增加了重量、尺寸和制造成本。 因此,需要一种精确而经济的手段,在尽可能短的时间里,通过多次改变几何形 A crankshaft design, subject to time constraints, often do not meet the requirements of optimization. Empirical methods and stress concentration methods, due to some unknown factors, the design will be biased to conservative. Repeated trial method in the short term can not get the required data. In this way, not only the crankshaft, but also the entire engine, the non-optimal design adds weight, size and manufacturing costs. Therefore, there is a need for an accurate and economical means to change the geometry by changing the geometry many times in the shortest possible time
