Jack, the Siemens PLM Software human simulation modeling tool that's part of the Tecnomatix digital manufacturing offering, got a little remodeling of its own with a new point release that pushes usability and productivity enhancements to facilitate easier, more accurate ergonomic studies.
Think of Jack (and there is a Jill) as digital manufacturing software's equivalent to gaming avatars. The digital humans are deployed on to digital factory floors, for example, to test and simulate safety conditions surrounding different machinery or to explore ergonomic conditions like reachability when assembling the virtual product. We've been reporting on Jack and other human simulation modeling tools for some time. But they've remained somewhat niche applications deployed by the pockets of large automotive OEMs and other manufacturers that have gone far down the path of digital prototyping.
Jack 7.1 comes with additional anthropometric databases, including those representing Japan and Korea.
Thanks to technology advances and an increased focus on ergonomics and safety on the factory floor, the use of human simulation modeling is becoming more widespread, according to Tom Hoffman, Siemens PLM Software's global marketing director for manufacturing engineering software solutions. Not only is the software starting to be used more readily in its traditional applications of ergonomics around product design and safety on the factory floor, but it's also starting to be used in specialized ways around maintenance and training. For example, Hoffman says the Department of Defense is increasing its deployment of tools like Jack to explore how vehicles get serviced in the field, and other companies are branching out and using the tools for training around service operations.
"We're seeing an uptick in interest, and we're seeing a lot of new technology come on board that makes human simulation tools more accessible," Hoffman told us. Specifically, more accessible motion capture technology, better graphics capabilities, and interactive interface systems like Microsoft's Kinect are pushing the envelope and opening doors for new use cases for the tools.
In its latest release of Jack, Siemens PLM Software has focused on making the software more accessible, as well as making productivity enhancements to help encourage broader use. Jack 7.1 includes new anthropometric databases, including those for Japan and Korea, to ensure populations in those areas are properly represented. In addition, the upgrade includes enhancements for posture prediction for seated activities and for disembodied hands. The seated posture tool, for instance, predicts overall body posture when a digital avatar needs to reach around and grab parts from a seated position. There is also a more accessible measurement tool -- a feature enhancement that was added based on user demand.
This looks like a cool app, Beth. I wasn't aware of human simulation software efforts, and it sure makes a lot of sense. My question is, considering how radically different the sizes and shapes of people can be, does this software allow tweaking of dimensions? Is it based on certain fixed "average" dimensions, or does it vary around the world, as average size varies within different populations?
Yes, that makes sense, Beth. I would imagine this technology would be particularly usefull in helping to design effective safety curtains and other safety applications.
Jack might be able to help companies avoid some of the design miscues that are centered more around ergonomics and how products come together. The simulation tool is really aimed at laying out an efficient and optimal factory floor, making it safer and more expedient for workers to assemble product and perform other tasks on the production line.
Fascinating article, Beth. I wonder if Jack might be able to avoid some of the ridiculous design problems that come up in the Made by Monkeys blog. Often we see problems that arise because people just didn't think things through. Perhaps Jack can avoid some of those problems.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
