英国豪华跑车制造商阿斯顿·马丁has announced a new collaboration with fluid power systems manufacturerDomin和Cranfield University为了开发使用3D打印的“世界领先”悬架系统。
Named the Full Active Suspension Technology (FAST) project, the partnership will leverage Domin’s patented technology, which involves additive manufacturing, to develop an industry-standard suspension system for the luxury car sector over the next six months.
然后，系统原型将完全安装在阿斯顿·马丁（Aston Martin）的一辆豪华跑车和定制测试台上测试的现实世界中。成功完成项目后，合作伙伴将把注意力转向创建悬架系统的生产单元。
多米诺的专利阀门技术
流体动力系统利用压力下利用液体或气体来产生和发射能量，并且在跨越方程式，汽车，空间，航空航天，移动液压和工业厂的市场中通常使用。诸如此类的活动系统能够比大而重的传统悬架系统更有效地适应道路表面的不断变化。
The design of the suspension system for Aston Martin will be based on Domin’s patented valve technology, involving a 3D printed core that contains 25 fluid galleries working in unison to transport hydraulic fluid throughout the system. The curvilinear nature of the unit intervals will be made possible by 3D printing and Domin’s advanced machining capabilities, which allow for the required mechanical properties of the suspension system. According to Domin, the FAST system will provide “infinite” variability in damping with a step response of just 0.015 seconds, and will weight less than 4kg per unit.
Domin以前曾与全球工程公司合作Renishaw到redevelop some of its fluid power system components, including its high-performancedirect drive servo valves用于将信号转换为压力。Domer利用Renishaw的Metal 3D打印技术来生产重新设计的阀，该阀制造了更小，更便宜，更高效。
Testing the FAST suspension system
克兰菲尔德大学将在整个快速项目中提供车辆建模和早期验证，该项目由低排放车辆办公室通过利基车辆网络。然后，对系统的现实测试将开始，其中一辆阿斯顿·马丁（Aston Martin）的一辆跑车在定制测试台上配备了原型。
在测试阶段,平台将复制the precise modes of resonance and the conditions the unit will undergo during use, putting the suspension system’s high-performance capabilities to the test and ensuring its mechanical robustness. Once the six-month FAST project is concluded, the team will showcase the complete suspension system and reveal how it performed during the testing phase.
展望未来，合作伙伴将利用其工程设计和3D打印功能来生产悬架系统的生产单元，最终目的是开发汽车领域内悬架的行业标准。
利用3D打印用于汽车
这不是阿斯顿·马丁（Aston MartinAM-RB 003概念超级跑车unveiled at the日内瓦车展在2019年。该公司使用3D打印来制造车辆内部内部的大和小零件，以改善其轻量级特性，此外还使用CAD 3D建模软件在汽车中创建复杂的参数形式。
In addition, earlier this year product engineering firm卡勒姆使用MakerbotMETHOD X 3D printer to produce custom parts for a限量版阿斯顿·马丁超级跑车, the Vanquish 25.
在其他地方，近年来，汽车行业的一些知名人士也接受了3D打印，以创建增强的最终用途零件。
For instance, researchers from theFraunhofer IAPT与工程师合作菲亚特克莱斯勒汽车到3D打印增强的悬架零件为了削减生产成本和交货时间，其中一辆汽车，而意大利豪华跑车制造商兰博基尼已经使用了基于硅谷的3D打印组件碳在里面其Urus Super SUV的建造。
同时，保时捷已经与机床生产商合作特朗普和automotive parts firm马勒到引擎的3D打印活塞它的911超级跑车，还招募了3D打印机制造商的服务SLM解决方案到print aproof of concept E-drive housing对于跑车的前轴。
