Abstract

Abstract: To obtain the loads on the walking support unit of a shearer during the cutting processes, a 6-order model was established by applying the theories of the classical mechanics, and the disadvantages of the model were analyzed. Aiming at the over constrained problems caused by the 4 supporting points between the shearer and the scraper machine, the mechanics model for the entire shearer was proposed by using the deformation compatible equation. The loads on the left driving roller and the right driving roller were achieved by the experiments, and the loads were input into the model. The model was numerically solved by employing the successive discrimination method. The solving results show that the forces in Y direction on the left guiding boot and the left smooth boot are as smaller than that on the right sides, the axial forces on the two guiding boots are small but the directions of them are opposite. The solving results were validated by the experiments, and the results show that the model is effective.

摘要： 为了获取采煤机截割工作过程中行走支撑部件的载荷，采用经典力学理论建立了采煤机整机6阶模型，分析了模型求解时存在的不足，针对采煤机与刮板机间的四点支撑而引起的过约束问题，采用变形协调原理建立采煤机整机的受力模型，通过实验方法获取了左右驱动滚筒的载荷，并将其作为模型输入，采用逐步判别法进行数值求解。结果表明：左导向滑靴和平滑靴在Y向的受力比右侧小，两个导向滑靴的轴向受力相对较小且方向相反。最后通过实验对求解结果有效性进行了验证。
