Analyses on the roller structure of equivalent honeycombs for forest harvester under impact loading

The Characteristics of the Deformation of a Feeding Roller with Double V-Wings Honeycomb under Driven Modes with Different Rotation Rates and Axial Compressions

“…Based on the roll-shaped double-V honeycomb structure proposed by Qu [7], the structural parameters in Figure 2b were set, where t is the wall thickness, l is the half-width of the cell, θ 1 is the lower cell angle, θ 2 is the upper cell angle, r is the half-width of the load-bearing wing, L is the number of layers, N is the number of cell elements, R is the outer diameter of the roller, R 0 is the inner diameter of the roller, and T is the width of the roller. The structural model parameters used in the experiment in this article are shown in Table 1.…”

“…However, there is little research on improving the structure of the feed roller itself. The damage to logs and the feeding roller of LAKO 43 forest harvester [7].…”

“…The Poisson's ratio and energy absorption capacity were studied with different arc angles at different compression speeds using finite element methods. The damage to logs and the feeding roller of LAKO 43 forest harvester [7].…”

“…Zhu et al [39] studied the coupling relationship between the cell structure parameters and the contact area of the DVWH feed roller. Qu et al [7] divided the equivalent honeycomb group of the structure and conducted dynamic response analysis using simulation. Zhang et al [40] divided roller-shaped honeycomb structures of different sizes into three levels based on density and studied their radial compression responses.…”
