ATV是全地形车的英文缩写,在国内通常被称为沙滩车。该车型区别于其他小轿车、客车的主要特性在于:车排量通常为(200~300)ml,额定功率通常为10kW;突出越野性能,适用于各种路面包括泥地、沼泽地、沙地等;广泛应用于农业、林业、地质石油勘探等行业,而且也可用于军事领域。本文首先对全地形车体覆盖件的总体布局、车体构件刚度以及工艺性进行了研究,其次在软件中建立覆盖件扣件的数据模型,用通用数据格式将模型导入到ANSYS环境中,建立扣件的有限元模型。用有限元理论分析扣件不同部位应力应变特性。针对出现的问题提出了一种基于油泥模型的现实装配和CAD结构辅助设计相结合的全地形车体覆盖件并行设计方法。
ATV is an acronym for ATVs, commonly known in the country as ATVs. This model is different from other cars, the main features of the bus is: the car displacement is usually (200 ~ 300) ml, the rated power is usually 10kW; outstanding off-road performance, suitable for a variety of pavement including mud, marsh, sand Etc .; widely used in agriculture, forestry, geological petroleum exploration and other industries, but also can be used in the military field. In this paper, the overall layout of the all-terrain vehicle body cover, the rigidity of the vehicle body member and the technology of the vehicle body are researched. Secondly, the data model of the cover fastener is established in the software. The general data format is used to import the model into the ANSYS environment. Fastener finite element model. Stress and Strain Characteristics Analysis of Different Parts of Fastener by Finite Element Method. Aiming at the problems that occurred, a parallel design method of all terrain vehicle body panel covering based on the actual model of sludge model and the CAD structure aided design was proposed.
