Torsional Strength Analysis of Heavy Truck Drive Shaft

摘要: 本文采用有限元方法对重型卡车传动轴的扭转强度进行分析，系统地分析了传动轴各部件在扭转作用下的应力分布规律。研究发现了传动轴扭转强度的相对薄弱处，并对照试验结果验证了传动轴有限元模型的正确性，在此基础上提出了传动轴结构设计优化的建议。

Abstract: The torsional strength of the drive shaft of the heavy-duty truck was analyzed by using the finite element method. The relatively weak point of the drive shaft was obtained by analyzing the stress distribution of each component of the drive shaft under torsion. The finite element model for the drive shaft is verified by the experimental results, on which the design optimization suggestions of the structure for the drive shaft were put forward.
