绕制卡簧用心轴直径的理论推导与经验公式

Theoretical Inference and Experiential Formulas of Mandrel Diameter Applied to Wind Garter Spring

用塑性力学的残余变形理论导出了绕制钢丝卡簧时其心轴直径与卡簧直径的关系式 。

The present paper gives the relations between mandrel diameter and garter spring diameter when winding garter spring with remains distortion theory of plastic dynamics ,and the experiential formulas when winding garter spring using middle or advanced spring wire, and how to choose mandrel diameter when hot or cold winding.
