目前,在柴油机的结构设计中广泛地使用有限元素法。它可以分析柴油机零件的应力、应变、变形和温度分布等,从而对受力零件进行强度校核。在计算时,对于比较简单的零件一般都简化成平面问题或轴对称问题,而对于比较复杂的零件虽然可采用三维有限元素分析,但计算前的予处理较复杂并常常受计算机容量的限制。另外,柴油机零件之间有许多配
At present, the finite element method is widely used in the structural design of diesel engines. It can analyze the stress, strain, deformation and temperature distribution of diesel engine parts so as to check the strength of the stressed parts. In the calculation, simple parts are generally simplified to planar problems or axisymmetric problems, while for more complex parts, although three-dimensional finite element analysis can be used, pre-calculation pre-processing is more complicated and often limited by the computer capacity. In addition, there are many parts between the diesel engine parts
