摘要
采用数字化设计方法,创新地将悬架系统装配在越野卡丁车上,以轻量化为目标,设计了车架及车身,并且分析了车架轻量化前后的典型工况下的应力图与位移图;利用焊接和3D打印技术对车架和操控系统的机构进行了制作、安装与调试。最后对加工方法与安装调试方案进行了优化。经过性能测试后,发现整车的动力性能及操控性能有所提升。该悬架系统的设计、匹配及制作过程为改进低速电动车(旅游观光车)的舒适性设计提供了参考,具有很好的应用前景。
This paper uses the digital design method to assemble the suspension system on the off-road kart innovatively.Aiming at lightweight,the frame and body are designed,and the stress diagram and displacement diagram under typical working conditions before and after the frame lightweight are analyzed.The frame and control system mechanism are manufactured,installed and debugged by using welding and 3D printing technology.Finally,the processing method and installation and debugging scheme are optimized.After the performance test,it is found that the power and handling of the vehicle are improved.The design,matching and manufacturing process of the suspension system provide a reference for improving the comfort design of low-speed electric vehicles(sightseeing vehicles),and have a good application prospect.
