| 摘 要： | 预应力钢丝缠绕剖分-组合挤压筒与传统挤压筒相比具有重量轻、疲劳性能好、制造难度与成本低等优势.传统的预应力钢丝缠绕筒体理论计算方法忽略了温度的影响,不适宜于热挤压筒的设计计算.该文采用线性热弹性理论、预应力钢丝缠绕理论以及弹性力学理论对挤压筒在预紧状态、预热状态和工作状态下的应力分布分别进行了分析,得出应力分布的解析公...

| Abstract: | Wire winded subdivided-combined extrusion containers has a wide range of advantages over traditional extrusion containers such as lower weight,improved fatigue performance,easier to manufacture and lower cost.Classic analytical solutions are derived without considering the influence of temperature which apparently cannot be applied to design a hot extrusion container.The theoretical derivation of stress distribution based on the consumption of a one-dimensional steady state temperature field was conducted.T... |
