| 摘 要： | 对滤袋脉冲喷吹清灰的力学机理作了研究。用柔性薄膜模拟滤袋，建立了薄膜在脉冲荷载作用下的振动议程。用Laplace变换求解上述方程，得出薄膜振动时的加速度随时间变化规律，并给出了滤袋参数与脉冲喷吹时间对最大反向加速度影响的数据。

| Abstract: | The mechanic behavior of dust cleaning using pulse jet is studied.The vibration equation of filter bag under impulsive loading is established by making use of the equation of flexible membrane.The above equation is solved by Laplace transform technique and the variation of acceleration of the flexible membrane with time is obtained.The influence of the parameters of the filter bag and pulse jet time upon the maximum opposite acceleration of the flexible membrane is also discussed. |
