Study and Simulation of Thermal Shock Vibration Elimination for Firecrackers Bundle Tube Machine

鞭炮捆筒机在工作过程中,电机到主轴采用皮带传动。火药靠皮带的两侧面与轮槽侧面压紧产生摩擦力进行动力传递的,在摩擦热载荷作用下会诱发机器结构的振动。传统的PID振动控制方法需要大幅调整参数,去满足热载荷作用下的振动控制要求,容易引发参数过量失调,振动控制效果不佳。提出基于模糊自适应PID控制算法的鞭炮捆筒机热冲击振动消除方法。计算V带基准长度,通过运算获取实际中心距离,研究了鞭炮捆筒机带轮振动关系。计算热冲击振动信号与控制参数之间的关联性,并对热冲击振动信号进行离散化处理,对离散化处理结果进行误差补偿,实现热冲击振动消除。实验结果表明,利用改进算法进行鞭炮捆筒机热冲击振动消除,能够有效提高消除的准确性,提高鞭炮捆筒机的应用价值。

The traditional PID vibration control method requires to adjust a substantial parameters, it easily brings excessive disorder parameters and poor vibration control effect. This paper proposes a method to eliminate the hot impact vibration for firecrackers bundle tube machine based on fuzzy adaptive PID control algorithm. Firstly, the refer- ence length of the V - belt and the actual center distance are calculated. Then the correlation between thermal shock vibration signal and the control parameters are obtained, and the thermal shock vibration signal is discretized and the error is compensated. Ultimately thermal shock can be eliminated. Experimental results show that the proposed algorithm can effectively improve the accuracy of elimination and increase the application value of firecrackers bundle tube machines.
