| Abstract: | Based on the shape characteristic and the quality of wood-working circular sawblade, according to Rayleigh-Ritz method,the function of shape characteristic was established to be suitable for wood-working circular sawblade. The method of polar coordinates was applied to deduce the vibration equations of wood-working circular sawblade. The establishment of vibration equations can provide theory basis for vibration model and stress analysis,exploring the noise mechanism, reducing the transverse amplitude of wood-working circular sawblade machine,improving the saw accuracy and the percentage of material and reducing noise pollution. |
