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 found that the maximum stress value of the crankshaft appears at the central rounded corner of the connection between the crank arm and the crank pin, and its value is 260.2MPa. Finally, the value is brought into the IACS algorithm to check the strength of the crankshaft, and the value obtained by the traditional IACS algorithm is compared. The results all meet the strength requirements and the strength of the crankshaft is qualified.
