【摘要】：随着我国经济高速发展,交通运输业也越来越发达,轻型环保的汽车零部件的研发工作越来越受到关注。本文以16吨单点悬挂平衡轴与安装托架优化设计为例,在保证载重指标的前提下,尽量使汽车质量减轻,在动力不变的前提下,能运载更多货物,在经济层面有着非常重要的实际意义。对企业而言,由于资金与技术的制约,新材料和先进的制造工艺不能应用到生产中,因此,要达到轻量化目标,对结构进行改进是最广泛的方法。本文以16吨单点悬挂的平衡轴、安装托架为研究对象,在考虑悬挂要求适应多工况的情况下,基于SolidWorks2013软件的建模和有限元数值仿真分析方法,在满足其强度要求的情况下,对平衡轴的尺寸与安装托架的前后左右侧板尺寸作了相应的优化,分析在额定静载重、额定载重急刹车、转弯、额载转弯急刹车四种工况下平衡轴、安装托架的应力图、位移图和应变图,得出不同工况下的最大应力值及其所在位置,使其达到轻量化目标。在本着节约成本的目标出发,对平衡轴螺母也做了优化设计。平衡轴螺母凸台与挡圈凸台装配关系作出了修改,去掉凸台。采用规格小的钢管进行加工,节约加工用料,同时减少了加工量,提高加工效率。
[Abstract]:With the rapid development of China's economy, the traffic and transportation industry is becoming more and more developed, and the research and development of light and environment-friendly automobile parts have been paid more and more attention. Taking the optimization design of the 16 tons single point suspension balance shaft and the mounting bracket as an example, under the premise of ensuring the load index, minimizing the automobile quality and carrying more goods under the premise of constant power is of great practical significance in the economic level. For enterprises, due to the constraints of capital and technology, new materials and advanced manufacturing processes can not be applied to production. Therefore, in order to achieve lightweight objectives, improving structure is the most widely used method. In this paper, 16 tons of single point suspension balance shaft, mounting bracket as the research object, considering the suspension requirements to adapt to many conditions under the condition of modeling and analysis method of SolidWorks2013 software and the finite element numerical simulation based on the situation, meet the strength requirements, the size of the balance shaft and mounting brackets around the plate size the corresponding optimization analysis in the rated static load, rated load and rated load braking, turning turning brakes four conditions of balance shaft, mounting bracket, stress displacement and strain diagram, obtained under different working conditions of the stress value and its position, so as to reach the goal of lightweight. On the basis of the goal of saving cost, the optimum design of the balance axle nut is also made. The assembly relationship of the balancing shaft nut bump and the ring bump is modified to remove the protruding table. The small size steel pipe is used to save the processing material, at the same time, the processing quantity is reduced and the processing efficiency is improved.
