摘要:

 为解决凹坑换热管生产成本高、加工效率低的问题,设计了一种多节距快速成形挤压装置,并采用数值仿真方法考察挤压深度D、挤压间距P和压头半径R对成形性能的影响。基于响应曲面法,建立挤压成形参数与成形力学性能的多元回归方程。结果表明:回归方程是可靠有效的,可用于预测凹坑换热管的力学响应。采用响应曲面法研究挤压成形参数对光管应力、等效塑性应变和挤压力的影响,得到用于预测凹坑换热管成形力学响应的响应曲面模型。建立了二元交互回归预测模型,预测值与模拟值误差小于0.5%,可以更加直观地反映各挤压成形参数对成形力学性能的影响,有助于凹坑换热管的结构设计及生产制造,为凹坑换热管的结构设计及生产制造提供理论支撑。

 In order to solve the problems of high production cost and low processing efficiency of dimpled heat exchange tube, a extrusion device for multi-pitch rapid forming was designed, and the influences of extrusion depth D, extrusion interval P and indenter radius R on the forming performance were investigated by numerical simulation. Then, based on the response surface method, a multiple regression equation of extrusion forming parameters and forming mechanical properties was established. The results show that the regression equation is reliable and effective, which can be used to predict the mechanical response of dimpled heat exchange tube. The response surface method is used to study the influences of extrusion forming parameters on the stress, equivalent plastic strain and extrusion force of bare tube, and a response surface model for predicting the mechanical response of dimpled heat exchange tube is obtained. Furthermore, a binary interaction regression prediction model is established, and the error between the predicted and simulated values is less than 0.5%, which can more intuitively reflect the influence of various extrusion forming parameters on the forming mechanical properties, and is helpful for the structural design and manufacture of dimpled heat exchange tube, which provides theoretical support for the structural design and manufacture of dimpled heat exchange tube.
