How Autodesk Research uses Markforged 3D printing

In advanced R&D, "good enough" doesn't cut it. To pioneer its Performance-Aided Design (PAD) workflow, Autodesk Research partnered with Markforged to close the gap between digital simulation and reality. Using sensors and digital twins, PAD replaces delayed field reports with real-time feedback. To test this high-stakes system, Autodesk built massive UAV platforms -- including a 300-lb aircraft. Facing extreme dynamic loads and weather, these drones provide the ultimate torture test for rapid design iteration.

Radio Flyer cuts ebike prototype time radically with Fuse X1 large-format SLS 3D printer

Radio Flyer cut prototype lead times for its Flyer Loop cargo ebike frame from two months to two days using Formlabs' new Fuse X1 SLS large-format 3D printer. "We can now print an entire Flyer Loop cargo ebike overnight and be gluing it together the next day," said Agostino LoBello, product development engineer at Radio Flyer. "I can iterate three times as often with nine times less labor." The Fuse X1 delivers production-quality parts with 50% lower costs and triple the throughput of comparable industrial systems, featuring automated powder handling and a compact, easy-to-install design.

Engineer's Toolbox: How to pin a shaft and hub assembly properly

One of the primary benefits of using a coiled spring pin to affix a hub or gear to a shaft is the coiled pin's ability to prevent hole damage. Another is the coiled pin absorbs wider hole tolerances than any other press-fit pin. This translates to lower total manufacturing costs of the assembly. However, there are a few design guidelines that must be adhered to in order to achieve the maximum strength of the pinned system and prevent damage to the assembly.

Army developing improved active protection systems for vehicle armor

Col. Kevin Vanyo, program manager for Emerging Capabilities, U.S. Army Tank Automotive Research Development and Engineering Center, said the limits have been reached on adding more armor to the Abrams tank, like the one pictured here. He said some bridges cannot hold the weight of a 78-ton tank. Vanyo spoke Dec. 1, 2017, at the Future Ground Combat Vehicle Summit in Livonia, MI. [Photo Credit: U.S. Army photo]

 

 

 

 

By David Vergun, U.S. Army

Ever since the advent of wheeled and tracked tactical vehicles, better protection has meant more armor -- with a tradeoff in speed and weight, said Col. Kevin Vanyo, program manager for Emerging Capabilities at the U.S. Army Tank Automotive Research Development, and Engineering Center.

Vanyo spoke Dec. 1, 2017, at the Future Ground Combat Vehicle Summit in Livonia, MI.

"Today, we need to adapt differently to threats, not just by adding more armor," he said, noting that the Abrams tank today is so heavy, transporting it is a problem and many bridges are not strong enough to support its weight.

With weapons becoming more potent, adding more armor just isn't feasible, he added. A new approach is needed.

Armor plating that protects Soldiers inside vehicles is known as "passive protection," because it doesn't do anything except deflect or absorb blasts and projectiles.

Active protection systems, or APS, is what Vanyo and his team are advocating, developing, and eventually hoping to field.

Vanyo explained that active protection measures are a suite of responses that will increase survivability of the platforms -- and of those personnel inside.

The measures can be grouped into two categories, he explained: hard kill and soft kill. Soft kill measures include sensors that can detect signatures from weapons and then interfere with those weapons using electro-magnetic countermeasures. Hard kill refers to physical countermeasures such as blast or projectiles that destroy or divert incoming fire.

The near-term effort to develop hard kill and soft kill countermeasures is a program known as Modular Active Protection System, or MAPS, he said.

Unfortunately, there's been a lot of misunderstanding about MAPS, Vanyo said, and a lot of that has to do with the name.

"MAPS is a framework for a modular, open-systems architecture. It is not an active protection system," he said, explaining that this framework consists of the controller software and hardware that will allow the active protection system to function once it is developed.

The Army is pursing three variants of MAPS, he said: Trophy APS, for use on the Abrams; Iron Curtain APS, for use on the Stryker; and Iron Fist APS, for use on the Bradley.

It is hoped that Trophy APS will be fielded by 2020, he said. Regarding the other two variants, a decision will be made during the second quarter of fiscal year 2018.

Maj. Gen. John Charlton, commander, Army Test and Evaluation Command, agreed that mixing an active with a passive protection system is the way to go.

Even with all of its armor, "It's amazing what an explosively formed projectile can do to a 78-ton Abrams," he said, having witnessed the damage at his Alabama test center facility in Redstone Arsenal.

Personnel at the arsenal are working on developing an APS and are testing various systems that can be fielded once MAPS has matured.

The concern right now, he said, is understanding the signal that APS produces and if that signal might interfere with other vehicle software, or provide its own signature that could be picked up by enemy sensors.

Getting APS right will involve pooling engineers from across the Army and other service laboratories, along with help from industry, he said, adding that he hopes to see Soldier testing in as little as two years.
