汽车轮毂ANSYS分析毕业论文

给楼主一个较英式的翻译！The optimization of the drive axle casing of a cross-country vehicle by the application of ANSYS , a 3-D model of drive axle casing was built to analyze the stress status of the casing under different working conditions, and the maximum pressure on the drive axle casing was determined by algorithm. Then, the 3-D model was introduced into the ANSYS software for various processing such as mesh generation, additions of freedom degree and stress, etc. The next step was to conduct finite element analysis of stress status on the axle casing and obtain the result of algorithm. Finally, optimization was carried out based on the objectives of achieving the minimum weight and the uniform stress distribution. After analytical verification, it was established that this optimization design conforms to the engineering requirements.

你想用ANSYS分析什么，要想清楚，在这里也应该说清楚。想做螺栓的受力分析，讨论螺栓的强度问题？亦或想做轮胎轮毂的受力分析，讨论轮毂的结构及强度问题，分析它的变形量？ 汽车从发动机输出动力经过离合器、变速箱、差速器、半轴一直到轮胎，都不是“加”上去的，而是传递，这叫动力传递。汽车的自重以及承受的载荷对轮胎、轮毂、螺栓的作用叫“施加”载荷。ANSYS分析是力的分析，要抓住力的作用点和方向，搞清楚这个力作用在哪里，不要被“扭矩”给弄迷糊了，按你这样的分析方法，到处找扭矩“加”在哪里，给你一百年你都找不出来。 半轴上的轮毂与轮胎的轮毂通过螺栓联接，拧紧螺栓后两者成为一个整体。在力学分析中，就不能把它们看做一个整体，仍将其视作独立的个体，那么，半轴轮毂上5个螺栓孔的切向力通过螺栓传递给轮胎的轮毂，构成扭矩，完成汽车动力最终传递。注意了，轮胎轮毂承受的最大载荷在螺栓孔的切线方向。轮胎轮毂螺栓孔与螺栓的配合间隙比较大，螺栓受到剪切力，同时受到拉力，轮毂受到剪切作用。 汽车完整的动力传递路线：发动机——离合器——变速箱——差速器——花键——半轴轮毂——螺栓（小汽车4~8根，载重车几十根）——轮胎轮毂——轮胎。 对于轮毂来说，汽车的自重以及载人载货都是载荷，表面上看作用在轮胎的中心上，那是合力，实际上均匀分布在轮毂的螺栓上。 中间那个大孔是工艺孔，避开半轴轮毂锁紧螺母的干涉，最后会装上一个防尘罩，防尘罩也起美观作用。 搞ANSYS 分析，首先而且最重要的是要找到力的作用点及其方向！

This design uses the ANSYS software to optimize the drive axle shell of a off-road vehicle. Firstly, to establish a three-dimensional model of drive axle and analyze the stress conditions of the drive axle shell in different conditions, then figure out the maximum pressure of the driving axle shell. Secondly, to import the Three-dimensional model to the ANSYS software to do some works such as gridding partition, freedom of motion adding, pressure adding and so on，then make a finite element analysis to the strained status of the drive axle shell in order to output the results. Finally, to optimize the objective with the lightest weight, and to equalize the stress distribution。Analysis verified that this optimal design conforms the engineering requirements.驱动桥桥壳有多种译法：drive axle housing ，drive axle shell， driving axle shell 等等，为了简洁起见用drive axle shell给你全文分成三个层次，用firstly，sencondly和finally 分开，开头结尾句另起一行分段，显得条理清晰。

1、实体刹车盘实体刹车盘，就是一块用于刹车的金属盘。此类刹车盘结构简单，价格便宜。但是散热效果差，因此也导致热制动效果相对比较差2、普通通风型普通通风型是在实体刹车盘的基础上改善而来的。散热性能得到了增强，制动效果更稳定，目前大多数轿车用的就是这种刹车盘。3、多孔型刹车盘多孔型刹车盘具有更好的冷却性，更能缩短制动距离，制动效果更稳定，一般适用于高端车。4、划线型刹车盘可以将附着于刹车盘上的灰尘，碎屑排开，雨天路面潮湿时，亦可将雨水排掉，从而让车子不会因为刹车盘上有过多雨水影响制动性。5、陶瓷复合型刹车盘它由碳纤维、石墨和硅的混合物制成，无论是热制动还是冷制动，它的制动性能更好，使用寿命更长，一般用于高档轿车或高档跑车上。
