摘要

为了研究牵引速度对采煤机滚筒工作载荷的影响,建立截割部与牵引部相互耦合的动力学系统模型,并考虑截割阻抗为随机量,服从正态分布,运用数值仿真的方法对其求解,并对结果运用数理统计方法得出采煤机滚筒三向力的均值及标准差;研究结果表明,滚筒三向力的均值和方差随着初始牵引速度的增加呈递增趋势,最后经仿真值与实验测量值对比,验证了模型的准确性。

Abstract

In order to study the traction speed of shearer drum load effect,the establishment of cutting part and the traction part are mutually coupled system dynamics model,and consider the cut cutting impedance is a random quantity,obey the law of normal distribution,using numerical simulation method to solve the problem and the results using statistical methods to calculate the shearer drum to force the average value and the standard difference; the results of the study show that,the drum to the mean and variance of the force with the initial traction speed of increased progressively. Finally,the accuracy of the model is verified by comparing the simulation results with the experimental measurements.
