Are Digital Humans Cool?

Cool, isn’t it?

We used NX in combination with our digital human model called Jack to create this image. Other than the cool factor, these digital humans play a key role in digital manufacturing, both in product engineering and production optimization:

1. In product engineering, they ensure that buyers can use the product. For example, automotive companies use human models to validate the vehicle’s cockpit design to answer questions like, can the seat be adjusted for different drivers so that they can all reach all switches? The same is true for aerospace companies.

2. In production optimization, they validate the ergonomic aspects of assembly situations. For example, can a part be assembled or maintained? Have you ever tried to change the headlamp bulb in your car? If yes, then you know what I am talking about.



Digital human models can also be used to optimize workplaces in regards to process times.

In some cases it might be obvious that a certain task is not appropriate to be done by a worker several times a day, like lifting a heavy tire out of a box. In other cases scientific analysis, like e.g. NIOSH, Burandt-Schultetus or OWAS, can provide a precise result of the ergonomic situation and allow to keep the workers save.



The digital human model can be adjusted to several sizes, shapes and gender … OK, only two genders wink. BTW, Jack’s sister is Jill. If you want to get an impression, see more on this web page.
