摘　　要：在我国林区采伐作业和收集运输设备研究现状基础之上,提出新型履带式采伐剩余物翻转运输车所具备的特征要求。应用UG创建运输车三维虚拟模型,并对该虚拟模型进行运动仿真分析。在履带式林业机械运输车中引入翻转机构,研究翻转机构的结构和工作原理,提高运输车在空间范围有限和作业环境复杂条件下的工作能力。选取适应林内通行困难状况且可满足高效经济运输需求的履带式行走底盘。通过对运输车虚拟装配模型的研究,解决了各机构之间相互匹配和运动合理性问题,使设计方案得以优化,为后续实体样机生产奠定良好基础。With the research status of harvesting and transportation equipment in the forest areas of China, we put forward the characteristics and requirements of the new type of tracked logging slash turnover transport vehicle. We used UG to create a three-dimensional transport vehicle virtual model, and the virtual model for motion simulation analysis. In the crawler forestry machinery introduced the turnover mechanism, we studied the structure and working principle of turnover mechanism, and improved the work ability of transport vehicle in the limited space and complex operating conditions. We selected the crawler walking chassis that can adapt to difficult traffic conditions within the forest which met the needs of efficient and economic transportation. Through the research on the virtual assembly model of transportation vehicles, the problems of mutual matching and movement rationality among various mechanisms were solved, and the design scheme was optimized, which laid a good foundation for the subsequent production of physical prototypes.
