径向锻造过程工件旋转振动分析

径向锻造过程中,当锤头和工件接触时,工件逐渐进人停止状态,而当锤头完全脱离工件后,工件在弹性杆势能的作用下进人旋转振动状态,因此,选择合适刚度的弹性杆对工件的运动状态甚至工件加工质量具有十分重要的影响.结合解析法和有限单元法,对工件和弹性杆构成的旋转振动系统进行数学建模,分析了锻造过程中工件的旋转运动状态,并讨论了弹性...

Rotary vibration analysis of workpiece in radial forging process

During the radial forging process,the workpiece gradually becomes still while the hammer presses it.After the hammer moves up,the rotation movement of the workpiece goes to free vibration for the potential energy of the spring bars.The appropriate torsion stiffness of spring bars has a great effect on the vibration of the workpiece and the criteria of the stiffness are the key parameters in the radial forging process.The mathematical model was built for the rotation vibration system constituted by workpiece...
