目的研究超声振动在冷拔传动轴过程中起到的减摩降载作用。方法以冷拔45钢50mm的传动轴为研究对象,利用ANSYS软件分别对常规和超声振动冷拔传动轴过程进行了有限元模拟仿真,对冷拔力和接触压应力进行了分析。结果超声振动冷拔的冷拔力和接触压应力都不同程度地减小。结论与常规冷拔过程相比,超声振动冷拔可以有效地减小冷拔力和摩擦力,有利于提高表面综合性能。
Objective To study the effect of ultrasonic vibration in friction and load reduction during the cold drawing shaft. Methods The 50 mm shaft of cold drawing 45 steel was used as the object of study. The cold drawing shaft with ultrasonic vibration and the normal cold drawing were simulated by the finite element software ANSYS. The drawing force and the contact compressive stress were analyzed. Results Both the drawing force and the contact compressive stress were reduced to various degrees while it was imposed with ultrasonic vibration. Conclusion The results showed that the cold drawing shaft with ultrasonic vibration could effectively reduce the drawing force and friction force,and was beneficial for improving the comprehensive properties of surface.
