【摘要】：自从2010年第一届中国大学生方程式汽车大赛在中国举行以来,越来越多的高校车队参与到了这项比赛之中。为了能在比赛中取得优越的成绩,各个车队纷纷展开了对方程式赛车的研究。车架是方程式赛车的重要组成部分,几乎所有赛车零部件都需要安装在车架上。在比赛中,车架将受到路面的激励、各个总成的重力等各种力的作用,所以车架的性能优劣对比赛的成绩至关重要。如果车架性能不够好,就可能在比赛中发生变形甚至断裂,导致赛车无法继续比赛。同时,车架的抗变形能力会影响赛车的四轮定位参数,如果车架发生严重变形,将导致整车四轮定位参数发生变化,进而影响赛车的操稳性能。而且,车架的质量直接决定赛车的动力性与经济性,一个较轻的车架将会使赛车的动力性与经济性大大提高。但是在追求轻量化的同时,我们也要保证车架的强度刚度满足比赛要求,防止车架在比赛中发生失效,并对车架进行模态分析,防止赛车在比赛过程中发生共振现象。本文利用HyperMesh软件,首先对车架进行拓扑优化设计,实现一个从无到有的过程。根据拓扑优化密度分布图初步设计出方程式赛车的雏形。之后对车架的强度、刚度以及模态进行分析,保证车架在比赛过程中不会发生失效和共振现象。最后对初步设计的车架进行尺寸优化,进一步优化车架性能,并得出车架的最终模型。
[Abstract]:Since the first Chinese University Student Formula car Competition was held in China in 2010, more and more college teams have participated in the race. Teams have been studying Formula Racing. The frame is an important part of the Formula Racing, and almost all of the racing parts need to be mounted on the frame. During the race, the frame will be excited by the road. The gravity of each assembly and other forces, so the performance of the frame is crucial to the performance of the race. If the performance of the frame is not good enough, the frame may be distorted or even broken in the race, resulting in the car can not continue the race. At the same time, The anti-deformation ability of the frame will affect the four-wheel positioning parameters of the racing car. If the frame is seriously deformed, it will result in the change of the four-wheel positioning parameters of the whole car, and then affect the stability performance of the car. The quality of the frame directly determines the power and economy of the car. A lighter frame will greatly improve the power and economy of the car. However, while pursuing lightweight, we should also ensure that the strength and stiffness of the frame meet the requirements of the race. In order to prevent the frame from invalidation and modal analysis of the frame, and prevent the race car from resonance during the race, this paper uses HyperMesh software to optimize the topology design of the frame. Realize a process from nothing to existence. According to the topology optimization density distribution map, the prototype of the equation racing car is designed. Then, the strength, stiffness and mode of the frame are analyzed. Finally, the initial design of the frame size optimization, further optimize the performance of the frame, and get the final model of the frame.
