摘要
利用Autodesk Inventor软件创建四缸曲轴传动的零件特征单元和部件特征单元,并进行三维运动仿真,研究主轴颈的支承受力情况;输入特定的初始条件和驱动条件,通过仿真播放和输出图示获得主轴颈的周期性受力变化曲线,用于分析曲轴的平衡状态;根据转动惯性平衡条件和受力曲线,优化曲轴结构(平衡重),及早发现不足,提高设计效率和设计水平,降低设计成本。
Autodesk Inventor software is used to create part feature unit and component feature unit of four-cylinder crankshaft transmission.The three-dimensional motion simulation is carried out to study the bearing force of the main journal.The specific initial conditions and driving conditions are input,and the periodic force change curve of the main journal is obtained through simulation playback and output diagram,which is used to analyze the balance state of the crankshaft.According to the balance condition of inertia and the force curve,the crankshaft structure(balance weight)is optimized to find shortcomings early,improve design efficiency and design level,and reduce design costs.
