| 中文摘要: |
| 提出一种由圆柱、圆壳、圆盘结构组成的大尺寸圆形超声塑料焊接模具,并对其进行了耦合振动分析,同时给出了基于有限元分析的设计优化方法。分析及优化结果表明:对径向尺寸大于一个波长的圆柱形模具,柱-壳式结构的超声塑料焊接模具能获得良好的振动特性,是一种有效的大尺寸圆形辐射面模具的新结构。 |
| 英文摘要: |
| A kind of large-dimension circular ultrasonic plastic welding tool composed of cylinder, shell and disk is brought forward, and an analysis of its coupled vibration is made. Meanwhile the designing and optimizing method based on FEA is developed. The result of analysis and optimization shows that the cylinder-shell tool has good vibration performance when the radial size is more than one wavelength, so the cylinder-shell plastic welding tool is a kind of new valid structure for the tool with large-dimension circular radiation surface. |
