China3D printingNet, March 9th, British luxury sports car manufacturer Aston Martin (Aston Martin) announced a new cooperation with fluid power system manufacturers Domin and Cranfield University (Cranfield University) to develop and utilize3D printing“World Leading” Suspension System.
The partnership, called Full Active Suspension Technology (FAST), will use Domin’s patented technology (involving additive manufacturing) to develop industry-standard suspension systems for the luxury car sector in the next six months.
Then, the prototype of the system will be fully installed on a luxury sports car from Aston Martin and will be actually tested on a custom test bench. After successfully completing the project, the partners will turn their attention to the production unit that creates the suspension system.

Domin’s patented valve technology
Fluid power systems use liquid or gas under pressure to generate and transfer energy, and are commonly used in markets across Formula One, including automotive, aerospace, aerospace, mobile hydraulics and industrial equipment. Active systems such as these are more effective in adapting to constant changes in the road surface than cumbersome traditional suspension systems.
Aston Martin’s suspension system design will be based on Domin’s patented valve technology, involving3D printingThe core contains 25 fluid channels that work together to transfer hydraulic fluid throughout the system. 3D printingThe advanced processing capabilities of Domin and Domin will enable the curve characteristics of unit intervals, thereby realizing the mechanical performance required by the suspension system. According to Domin, the FAST system will provide “unlimited” variability in damping, with a step response of only 0.015 seconds and a weight per unit of less than 4kg.
Domin previously worked with global engineering company Renishaw (Renishaw) to redevelop some of its fluid power system components, including high-performance direct drive servo valves that convert signals into pressure.Domin uses Renishaw metal3D printingTechnology produced a redesigned valve that became smaller, cheaper, and more efficient.

Testing the FAST suspension system
Cranfield University will provide vehicle modeling and early verification throughout the FAST project, which is funded by the Office of Low Emission Vehicles through the Niche Vehicle Network. Then, actual testing of the system will begin, and one of the Aston Martin sports cars has been prototyped on a custom test bench.
In the testing phase, the rig will replicate the exact resonance mode and the conditions that the equipment will withstand during use, so as to test the high performance of the suspension system and ensure its mechanical robustness. Once the six-month FAST project is over, the team will demonstrate the complete suspension system and demonstrate its performance in the testing phase.
Looking to the future, partners will use their engineering design and3D printingThe functional production unit of the suspension system, the ultimate goal is to formulate industry standards for the suspension of the automotive industry.

This is not the first time Aston Martin has entered the field of additive manufacturing, but deployed in the production and design of the AM-RB 003 concept supercar that was unveiled at the 2019 Geneva Motor Show.3D printingtechnology.The company uses3D printingTechnology to manufacture large cars and large cars. In addition to using CAD 3D modeling software to create complex parameter forms in the car, it can also improve the small parts inside the car to improve its lightweight performance.
In addition, earlier this year, product engineering company CALLUM used Makerbot METHOD X 3D printingThe machine produced customized parts for the limited edition Aston Martin Vanquish 25 super sports car.
In other places, in recent years, some well-known companies in the automotive industry have also adopted3D printingTechnology to manufacture enhanced end-use parts.For example, researchers from Fraunhofer IAPT worked with engineers from Fiat Chrysler Automobiles3D printingEnhanced suspension parts to reduce production costs and delivery time, while the Italian luxury sports car manufacturer Lamborghini used3D printingCarbon, which is headquartered in Silicon Valley, provided legal services for the construction of its Urus Super SUV.
At the same time, Porsche has cooperated with machine tool manufacturer TRUMPF and auto parts company MAHLE to provide the engine for its 911 super sports car.3D printingPistons and also invited3D printingMachine manufacturer SLM Solutions provided services to print the proof-of-concept E-drive housing for the front axle of its sports car.
Porsche’s electronic drive housing was printed on the NXG X11 600 within 21 hours. The picture comes from SLM solutions.
