Aston Martin unveils new DBR22 sports car concept with Divergent 3D printed rear subframe

英国豪华跑车制造商Aston Martin已经引入了一个新的敞篷跑车,具有独特的发散技术-3D打印后组件。

据说阿斯顿·马丁(Aston Martin)在其705 hp DBR22两人座的后部的后部集成了由多个3D印刷铝制零件组成的支撑结构,以节省重量的方式。该子帧由Divergent Technologies构建,3D打印的Czinger 21c HyperCarand a supplier of major OEMs whose clients had until now, been shrouded in secrecy.

“Very excited to see some of our OEM programs come into the public light,” Czinger Vehicles Co-founder卢卡斯·辛格(Lukas Czinger)在LinkedIn上说。“The Divergent team has had the great pleasure of working with on of the world’s great brands, Aston Martin Lagonda Ltd, on existing and next generation production performance vehicles.”

发散技术的“无聊”系统

Divergent的业务主要围绕其不同的自适应生产系统,或“ DAPS”,是端到端硬件软件汇编平台,旨在替代传统汽车生产过程。由于其3D打印和生成设计的结合,DAPS是“模型不可知论”,因为它允许在同一机器上生产多个不同的汽车型号。

正如您想象的那样,考虑到其计算工程,打印和组装零件的能力,该系统还可以解锁快速迭代,而据说其灵活的设置使其比当前的汽车制造方法更有效,更环保。

迄今为止,该技术的最高知名度是Czinger 21c,这是一款耗资200万美元的超级跑车,速度为0-62 mph速度仅为1.9秒,由Divergent的姊妹公司开发Czinger Vehicles。As revealed in theCzinger 21c的古德伍德(Goodwood),该车辆的3D印刷底盘和零件都合并为3D打印节点,重量节省高达40%。

Over the last four months, the technology behind the 21C has earned significant backing, withDivergent授予1.6亿美元的资金during April, before gaining access to a $80 million credit facility in July. Later this month, Czinger Vehicles is also planning to unveil a new car at thePebble Beach车展。尽管这只野兽的性质仍然未知,但据说它依靠DAP来生产。

Aston Martin’s DBR22 ups AM ante

虽然DBR22旨在用作尖端生产技术的展示,但它并不是第一个以3D打印零件为特色的阿斯顿·马丁。2019年,阿斯顿·马丁的AM-RB 003概念车首次亮相日内瓦车展,配有3D打印的中央控制台,以及其他轻巧的内部组件。

从那时起,流体动力系统制造商Dominand克兰菲尔德大学与该公司合作开发了一个完整的阿斯顿·马丁3D打印悬架系统。Built upon Domin’s patented valve technology, in which a 3D printed core containing 25 fluid galleries work in unison to transport hydraulic fluid, the system is said to provide ‘infinite’ variability in damping, while weighing just 4kg.

然而,凭借其最新的未来派设计概念,阿斯顿·马丁(Aston Martin)现在通过将合并的结构元素引入高性能敞篷跑车,将其3D打印的应用提升到了新的水平。在蒙特雷汽车周上揭幕,开放式DBR22型DBR22造型类似于1956年DBR1与现代技术的造型,以及一种新的V12,在3.4秒内将其从0-60推动。

When it comes to the vehicle’s rear subframe, Aston Martin says that 3D printing the system enabled it to be made lighter without reducing its stiffness, in a way that’s perfect for making elements of “ultra-low volume models, where required.” This model, according to Divergent and Czinger Vehicles CEO Kevin Czinger, could be transformational for OEMs, and he aims to roll out DAPS more widely in future.

“ Divergent很荣幸能与阿斯顿·马丁·拉贡达(Aston Martin Lagonda)和其他主要全球OEM合作,以改变汽车设计和工程的未来,”凯文·辛格(Kevin Czinger)添加了LinkedIn。“从下个月和接下来的几年开始,Divergent团队将在美国和欧洲扩展多个模块化工厂来部署DAPS。”

“我们是主要OEM品牌的1级供应商,其销量生产计划适用于框架和悬架系统,其范围从每年的100辆车辆到2025年的数万千千年。”

3D printing-enabled high-powered exotics

阿斯顿·马丁(Aston Martin)并不是唯一可以转向3D打印的超级跑车制造商,并且该技术继续用作低量高价值车辆的定制零件的一种手段。去年年底,Spyros Panopoulos Automotive揭示是3D打印混乱Ultracar车身面板,以一种使它们轻巧的方式使其比第二秒的0-60速度降低。

该项目让人联想到罗丹汽车的部分3D印刷了“ fzero”,an upcoming hypercar that’s set to feature an additive manufactured gearbox. Believed to be the first of its kind, the transmission is being built to include a hydraulically-controlled differential, which helps manage the torque generated by its 1,000 bhp engine.

在较小的规模上,该技术也被该技术使用Arash Motor Company, which3D prints end-use electric hypercar parts。Specifically, usingMakerbot3D printers, the firm has managed to produce components ranging from prototype car models to carbon motor cartridges, electric motors and high-capacity batteries.
