摘要
This paper provides a method of determining the BWE digging force considering the characteristics of soil which needs to be excavated, bucket cutting contour, cutting speed and vertical vibration of the bucket wheel. Digging force depends on the specific force resistance to excavation (SFRE) and the total length of buckets cutting contours that are simultaneously in mesh with the material. The SFRE is conditioned by the characteristics of material, cutting speed and it is random variable, while the total length of buckets cutting contours depends on the number of buckets that are simultaneously in mesh with the soil and vertical oscillations of the bucket wheel. Total length of buckets cutting contours time function is determined considering moving of bucket wheel center point, based on a dynamic model of BWE in the vertical plane.
