| Abstract: | A kind of large-dimension circular ultrasonic plastic welding tool composed of cylinder, sheU 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. |
