摘要
本文在大量动态直剪试验的基础上,建立了散体在振动场作用下剪切试验的几个力学模型.所建立的模型考虑了散体的粘性、弹性和塑性的综合影响,能较好地分析振动场中剪力盒及试料的运动规律,为振动出矿基础理论的研究开辟了一条新途径.
Based on a large number of dynamic shear tests, several mechanical models of dynamic shear test of bulk materials have been established in this paper. The viscosity, elasticity and plasticity are involved in the mechanical models, and the motional pattern of shear box and sample under vibration can be analyzed accurately. Thus a new way has been developed for the study of the theory of vibrating ore drawing.
