Changsha metal 3D print for students making racing, speed of 130 km-3D printing, college students-IT information
Changsha University a group of "tech man" and "woman and man", they are self-financing, self-management, self-pressurized, working overtime just dig out the "3D metal printing-racing"--FNX-16, war for 2016 China formula student competition. According to public information, metal 3D printing as a concept car in China for the first. Today, Changsha University of specially organized for them a new car launches.
Crank out the country's first metal 3D printed concept car
"H-" 4 o'clock in the afternoon today, at jinpen Ridge campus of Polytechnic University sports ground on the runway, about 200 kilograms of FNX-16 around and make a high-speed bypass, measured at about 130 kilometers per hour, driving attitude stabilization, controlled agility. Racing and drifting, sometimes accelerating, attracted a large number of students watched, we cheer in unison. This is the first "3D metal printing-racing" in Changsha University-FNX-16 first, it is about going to war for 2016 China formula student competition.
"About 3 years ago, Motorsport, China introduced the concept of 3D printing of polymer materials, and today we made the first metal 3D printing for concept cars, these metal 3D printing parts stronger, more stable, more expensive, for me the most important thing is making more difficult. "Racing team leader Zhao Shusheng talks about the process of creation of this car. Changsha University of more than five, more than 300 college students before and after the relay for five years, to create a "FNX series" College formula, until September 18, 2016 is already the 5th "FNX-16" race. The car began its development in the last year, until this summer at the end of basic training. In the research phase, there are many students as early as eight o'clock at night. Funding, school funding is not enough, Zhao Shusheng and founder of some free from home took tens of thousands of Yuan, a leading 3D printing companies become sponsors, funded a team of more than 200,000 yuan.
From the learning-by-doing, and from design to manufacturing to adjust everything bought thousands of parts. Boys were sleepy sleep garage, no money himself chipped in to buy parts, summer school to process ... ...
Zhao Shucheng recalled that in order to debug engine, importuning they find a sponsor site, took a bus two hours to plant in the heat of summer, Dawn went out, came back a sky full of stars.
Today's students, tomorrow's China manufacturing 2025
Even more difficult is the metal 3D printing. 3D printing parts of a metal to tens of thousands of Yuan. Sponsored manufacturers just produce, design must be done by the students. For example to make a suspension post, rework 5 times. Instructor Yuan Xiang, manufacturers engineer Tang Gong, who, under the guidance of team redesigned, changed, matches, took a summer vacation, and finally the suspension system of pillars, rocker manufactured metal 3D printing methods, such as, and are the most advanced SLS-selective laser sintering technology, all parts fit together perfectly, works excellent.
"Including the intake manifold, wheels, steering wheels, aerodynamics, and many other components are used in 3D printing. The auto industry of the future will be better use of 3D printing technologies. "Team member Wang Hui said," If the mechanical production methods, lot to make a lot of small parts to different molds, machine tools. Using 3D printing technology, only on software modeling, import into the printer, and can print the entire sport system. ”
Formula student competition of China stipulates that vehicles must use four-stroke gasoline engine displacement up to 610cc, therefore, FNX-16 powered by a 600CC motorcycle engine. In order to make the racing better, team into power, suspension, bodywork and other groups, tried to make the cars more lightweight, stronger and more manipulative. At present, FNX-16 is only about 200 kilograms of weight, posture is much more stable than the previous version.
长沙大学生用金属
3D打印制造赛车，时速130公里 -
3D打印,大学生 - IT资讯
长沙理工大学有这样一群“理工男”和“女汉子”，他们自筹经费、自我管理、自我加压，加班加点捣鼓出了“金属3D打印赛车”——FNX-16，即将出征2016中国大学生方程式汽车大赛。据公开资料显示，以金属3D打印为概念的赛车，在国内尚为首创。今日，长沙理工大学专门为他们举办了新车发布会。
攒出的全国首台金属3D打印概念赛车
“轰——”今日下午4时，在理工大学金盆岭校区运动场跑道上，大约200千克重的FNX-16一圈又一圈地高速绕行，测得时速在130公里左右，行驶姿态稳定，操控敏捷。只见赛车时而漂移，时而加速，吸引了大量同学围观，大家齐声欢呼呐喊。这是全国首台“金属3D打印赛车”—FNX-16在长沙理工大学的首发仪式，它即将出征2016中国大学生方程式汽车大赛。
“大概3年前，中国赛车界引入了高分子材料3D打印的概念;今天，我们做出了全国首台金属3D打印为概念的赛车，这些金属3D打印的零部件更坚固、更稳定、费用更高，对我而言最重要的是制作难度更大。”赛车队队长赵树生谈起了这台车的创制过程。长沙理工大学前后五届、300多名大学生接力五年，制造出“FNX系列”大学生方程式赛车，到2016年9月18日已经是第5台即“FNX-16”赛车。这辆车在去年开始研制，一直到今年暑假结束时才基本定型。在攻关阶段，有很多同学都是早八点干到深夜。经费上，学校拨款不够，赵树生和一些创始人从家中无偿拿了数万元，一家业内领先的3D打印厂商成为赞助厂商，资助了团队20余万元。
他们从边干边学边摸索，从设计到制造再到调适，事无巨细，光零件就买了上千个。男孩子们困了就睡车库、没钱了就自己掏腰包凑钱买零件、寒暑假留校加工……
赵树成记得，为了调试发动机，他们软磨硬泡找到一个赞助场地，在酷热的夏天坐两个小时公交去厂房，天刚亮出门，回来时已是满天繁星。
今天的大学生创客，明天的中国制造2025
难上加难的就是金属3D打印。一个金属3D打印的零部件要上万元。赞助厂家只管生产，工程设计必须由大学生们来做。比方做一个悬架立柱，就返工了5次。在指导老师袁翔、厂商工程师唐工等人的指导下，团队重新设计、改图、做匹配，耗时一个暑假，终于将悬挂系统的立柱、摇臂等以金属3D打印的方式制造出来，而且用的是最先进的SLS选择性激光烧结技术，各零部件严丝合缝，运作优良。
“包括进气歧管、轮毂、方向盘、空气动力学套件等诸多零部件用的都是3D打印技术。未来的汽车工业将更广泛运用3D打印技术。”团队成员王慧介绍说，“如果采用机械制作方法，很多地方需要制造很多细小零件，要不同的模具、机床。运用3D打印技术后，只需要在软件上建模成型，导入到打印机器中，就可一次性打印出整个竞技系统。”
中国大学生方程式汽车大赛有规定：车辆必须使用排量不超过610cc的四冲程汽油机，因此，FNX-16采用的也是600CC摩托车发动机。为了让这台赛车比赛成绩更好，团队分成了动力、悬挂、车身等多个组，尽量让这台赛车更轻量化、更坚固、更具操控性。目前，FNX-16只有大约200千克重，行驶姿态也比上一个版本要稳定得多。
