依据煤体中冲击应力波的传播规律理论 ,利用冲击动力学、弹塑性理论、岩石破碎学的知识 ,对冲击式采煤机的冲壁厚度、刀齿密度、冲击频率、刀齿强度等参数之间的函数关系 ,以及同煤炭本身物理力学性质之间的关系进行研究。为改进和推广现有冲击式采煤机提供了必要的理论依据。
According to the theory of the propagation law of impact stress wave in coal body, using the knowledge of impact dynamics, elasto-plastic theory and rock breaking theory, the parameters of impact wall thickness, knife tooth density, impact frequency, knife tooth strength and so on As well as the relationship between the physical and mechanical properties of coal itself. It provides the necessary theoretical basis for improving and popularizing the existing shearer.
