Abstract
The article considers the multioperational felling-bunching machine proposed by the authors, the one equipped with an accumulating head (AH) and a bunching device. The MFBM is designed for felling small-diameter trees in the accumulation mode and processing small-diameter trees into bunches. The diameter of the bunches is 0.1-0.2 m with the length of 6 m. Compacted bunches can be transported by forwarders and timber carriers as ordinary assortments. The MFBM effectiveness was studied on mathematical models using simulation methods for two modes of machine operation. The first mode of the MFBM operation is performed without combining tree bunching with moving the machine between work sites and accumulating trees in the AH. The second mode includes combining these operations. For comparison, simulation experiments were carried out using a conventional LP-19 FBM. The LP-19 FBM performance when felling small-diameter trees with a volume of 0.046 m3 drops by almost 10 times as compared with felling trees with a volume of 0.4 m3. The MFBM performance in all modes and similar working conditions turned out to be 2-3 times as high compared to the LP-19 FBM performance. When felling small-diameter wood, the MFBM shows the highest performance in the mode of combining operations. The MFBM performance in this mode with an average volume of a small-diameter tree of 0.046 m3 and the number of trees on the site being 8 pcs. turned out to be three times as high compared with the LP-19 FBM.
