摘　　要：介绍了集材技术发展的历史及现状。对拖拉机集材进行了机械结构设计,并用 ANSYS 对减速器壳体进行了优化分析。实验证明理论分析可以满足实际生产的需求。实验数据表明拖拉机集材效率要高于 J -50 集材机的效率,为更进一步的研究提供了参考。In order to satisfy the need of sustainable development, it is necessary to give an explo- ring discussion of the effects of three logging methods on ecology. The development status of skidding is introduced. The mechanical structure of tractor skidder is designed and the intensity of the reducer shell is optimized by using ANSYS based on the finite element method. The practical application verifies that the theoretical analysis can satisfy the practical requirements. Experimen- tal data shows that the efficiency of tractor skidder is higher than that of J-50 skidder.
