摘要
利用DEFORM-3D有限元数值模拟软件对内螺纹的振动挤压进行了模拟。分析了影响振动挤压攻丝扭矩主要因素,基于模拟结果揭示出各主要因素对攻丝扭矩的影响及其变化的基本规律。这些规律对减小扭矩、提高内螺纹质量、改善攻丝效果都有一定理论和实践指导意义。
The process of vibration extrusion tapping is simulated by using DEFORM-3D FEM software.The paper analyzes those factors to influence the torque of vibration extrusion tapping.Upon the results,the basis rules are analyzed.These rules are valuable to decrease the torque of vibration extrusion tapping,to improve the quality of tapping and promote the practise use of vibration extrusion tapping.
