 PAGE \* MERGEFORMAT 18 汽车前盖和方向盘的三维造型设计 摘 要 汽车前盖与方向盘是汽车中不可缺少的一部分，方向盘是操纵汽车行驶方向的轮状装置。 最初的汽车是用舵来控制驾驶的。舵不能说不好，但是它会把汽车行驶中产生的剧烈振动传导给驾驶者，增加其控制方向的难度。当发动机被改为安装在车头部位之后，由于重量的增加，驾驶员根本没有办法再用车舵来驾驶汽车了。方向盘这种设计便应运而生，它在驾驶员与车轮之间引入的齿轮系统操作灵活，很好地隔绝了来自道路的剧烈振动。不仅如此，好的方向盘系统还能为驾驶者带来一种与道路亲密无间的感受。 本次设计主要通过对现有的汽车前盖与方向盘的结构进行分析和计算并应用SoildWorks的3D模拟仿真技术进行设计，使设计具有可视化效果，从而在设计中也能更好的进行分析，以提高设计的准确性。 关键词：前盖；方向盘；结构；分析 Auto Front Wheel And The Three-dimensional Modelling Design Abstract Author: Tutor: Auto front and steering is the indispensable part in automobile vehicle control, the steering wheel is in the direction of the device. The car was initially with rudder control of driving. Rudder cannot say, but it will take the car driver, violent vibration to increase the difficulty of its direction. When the engine is installed in the front position instead, due to the increased after the weight, the pilot is no way to drive a car ZaiYongChe rudder. The design of steering wheel, it will come into being in the driver and the wheels of the gear system introduced flexible operation, good isolation from the path of violent vibration. Not only such, good steering system also can bring a driver and intimate feelings. The design of the existing mainly through the cover and the steering wheel structure analysis and calculation and application of 3D simulation technology SoildWorks design, make visual effect, which is designed in the design can be analyzed, in order to improve the accuracy of the design.
