【摘要】：由于新疆地区气候特殊，冬季时间比较长，降雪比较多，因此寻找一种效率较高，结构比较简单，成本又低的扫雪方式成为目前的当务之急。与传统的融雪剂、物理微波、人工除雪相比，除雪机械具有应用范围广、耗能低、效率高、无污染等特点。因此在国外得到了迅速发展和广泛运用。本研究基于国内外已有的扫雪设备和方法的研究列出了雪的机械物理性，提出了一种适合新疆地区区情的小型扫雪设备的工作原理和设计方案，进行设计计算以及机构创新。对扫雪机重要的传动部分进行校核计算，还用UG NX7.0软件建立了扫雪机各个零部件的三维建模，创建三维实体模型，基于ANSYS Workbench软件对扫雪机重要零部件刷子进行有限元分析。本论文对小型路面机器扫雪车进行了深入的分析，并进一步完善了此机构，优化设计出此种扫雪装备。 在对本课题钻研中，主要采用了如下关键技术： （1）利用UG NX7.0软件三维实体建模技术和装配技术，创建了扫雪机零件的三维实体模型，完成了整机的三维实体装置模型，实现了面向装配的设计。（2）利用有限元分析的优化设计技术，对刷子关键零件进行了有限单元网格划分，进行了有限元动力分析。
[Abstract]:Because of the special climate, longer winter time and more snowfall in Xinjiang, it is urgent to find a snow-sweeping method with high efficiency, simple structure and low cost. Compared with traditional snowmelt, physical microwave and artificial snow removal, snow-removing machine has the characteristics of wide application, low energy consumption, high efficiency, no pollution and so on. As a result, it has been rapidly developed and widely used abroad. Based on the existing research on snow sweeping equipment and methods at home and abroad, this paper lists the mechanical physical properties of snow, and puts forward the working principle and design scheme of a small snow sweeping equipment suitable for the situation in Xinjiang region, and carries out design calculation and mechanism innovation. The important driving part of snow sweeper is checked and calculated, and the 3D modeling of each part of snow sweeper is established with UG NX7.0 software, and the 3D solid model is created. Based on ANSYS Workbench software, the brush of the important part of snow sweeper is analyzed by finite element method. In this paper, the small road machine snow sweeping vehicle is deeply analyzed, and the mechanism is further improved, and the snow clearing equipment is optimized and designed. In the research of this subject, the following key technologies are adopted: (1) the 3D solid model of snow sweeper parts is created by using 3D solid modeling technology and assembly technology of UG NX7.0 software. The 3D solid device model of the whole machine is completed and the assembly oriented design is realized. (2) based on the optimization design technology of finite element analysis, the key parts of brush are meshed with finite element and the finite element dynamic analysis is carried out.
