双层圆挤压筒过盈量参数优化设计和分析

Parameter-Optimizing Design and Analysis of Magnitude of Interference for Double-Layer Cylindrical Extrusion Chamber

对双层圆挤压筒内外衬套半径尺寸的确定进行理论计算和分析,将优选参数的计算结果进行比较。对具体的模型结构进行三维过盈-内压-热耦合分析,得出力学性能指标,确定最终设计参数。

The theoretical calculation and analysis are performed to determine the radius of inner and outer sleeves of doublelayer extrusion chamber; the calculated results of optimum parameters are compared with special analysis software. A simulated model is established to perform 3-D interference-internal pressure-thermal couple analysis on the specific design of extrusion chamber to obtain the mechanical property index and define the final design data.
