为了全面准确地了解ZL490FB型矿用防爆柴油机曲轴在服役过程中的疲劳特性,针对曲轴几何结构相对复杂的特点,笔者采用ABAQUS的子模型技术,对曲轴的疲劳强度进行了分析。在分析过程中,首先采用全局模型对曲轴的受力状况进行了初步分析,在此阶段可以尽可能地保持曲轴的几何结构和受力状况符合实际工况;再利用子模型对应力集中部位进行了详细分析。为曲轴的疲劳强度分析提供了一定的依据,也为复杂工程结构的力学分析提供了一种新的方法。
In order to comprehensively and accurately understand the fatigue characteristics of ZL490FB mine explosion-proof diesel engine crankshaft during service, in view of the relatively complicated crankshaft geometry, the authors used ABAQUS sub-model technology to analyze the fatigue strength of crankshaft. In the process of analysis, firstly, a global model was used to analyze the stress condition of the crankshaft. At this stage, the geometry and stress conditions of the crankshaft could be kept in line with the actual conditions. The sub-model was used to analyze the stress concentration sites A detailed analysis. It provides a basis for the fatigue strength analysis of crankshafts, and also provides a new method for the mechanical analysis of complex engineering structures.
