船用柴油机曲轴强度分析
Strength Analysis of Crankshaft of Marine Diesel Engine
以曲柄连杆机构为研究对象，采用三维建模软件建立曲轴的三维模型，利用AVLExcite PowerUnit软件搭建多体动力学计算模型，以获得进行曲轴有限元分析的边界条件，导入到有限元分析软件中获得曲轴的应力应变结果，发现曲轴的最大应力值出现在曲柄臂与曲柄销连接的中心圆角处，其值为260.2MPa，最终以该值带入IACS算法中进行对曲轴的强度进行了校核，并于通过传统IACS算法获得的值进行比较，其结果均满足强度要求，曲轴强度合格。
Taking the crank connecting rod mechanism as the research object, three-dimensional modeling software was used to establish the three-dimensional model of the crankshaft, and the multi-body dynamics calculation model was built by AVL Excite Power Unit software to obtain the boundary conditions for finite element analysis of the crankshaft, and the stress-strain results of the crankshaft were obtained by importing the finite element analysis software. It is f…查看全部>>
