Delmia SAFEWORK®Pro-Human Modeling
The Need
In the demanding global marketplace, ensuring that human fit, form and function are comprehensively addressed is becoming an increasingly important aspect of design. Manufacturers
and designers strive to develop products that conform to all
relevant Health and Safety standards and are
"user-friendly" while still maximizing the
productivity of their own workforce. Digital human modeling
technology can assist a designer to determine the
performance of people in the context of a workplace or a
product before it exists and throughout its entire
lifecycle. |

The Technology
SAFEWORK®
accurate manikin has the highest number of Anthropometric
Variables (104), Segments (99) and Degrees of Freedom (149).
It also has fully articulated spine & hand models as
well as joints with coupled range of motion. Moreover,
it unique Multivariate Algorithm for anthropometry
allows the user to create accurate virtual humans from
almost anywhere around the world. Finally, SAFEWORK®
unique Boundary Mannequin Approach is essential for a better
accommodation of targeted population. Other powerful
SAFEWORK?features include: Postural Analysis, Ergonomic
Analysis, Force and Comfort Assessment, Task Module,
Clothing Module, Animation Module, Collision Detection,
Vision, Library concept, direct and inverse kinematics and
more.
Human
Activity Analysis
SAFEWORK® ProTMhas been designed to
evaluate all elements of human performance, from static
posture analysis through to complex task activities. SAFEWORK® ProTMpossesses a range of tools and
methods that specifically analyze how a manikin will
interact with objects in the virtual environment. The NIOSH
81/91 and SNOOK&CIRIELLO equations measure the effects
of lifting/lowering, pushing/pulling and carrying to fully
optimize task performance. After inputting an initial and
final task posture, a designer can determine a number of
task variables such as Action Limit, Recommended Weight
Limit, and Maximum Lifting/Lowering Weight.

Vision
Analysis
The SAFEWORK® ProTMVision Module, derived from
the NASA 3000 Guidelines, contains an accurate vision
behavior model to imitate the realistic movement of the
human vision so that "what the manikin sees, the
operator sees?amp;quot; Four types of vision simulation are
provided: binocular, ambinocular, monocular left and
monocular right (stereoscopic viewing with advanced depth
perception, is available in the Virtual Reality Module).
Visual characteristics are displayed as peripheral cones,
central cones, blind spot cones and central spot cones that
permit the user to gain an insight into the manikin's
view.
Postural
Analysis
The SAFEWORK® ProTMPostural Analysis Module
permits users to quantitively and qualitatively analyze all
aspects of manikin posture. Whole body and localized
postures can be examined, scored and iterated to determine
operator comfort and performance in accordance with any
established comfort database. User-friendly dialogue panels
provide posture information for all segments of the manikin,
and color-coding techniques allow for quick identification
of problem areas and positioning of the manikin in an
optimized posture.
Virtual
Reality
The use of a Virtual Reality environment in ergonomics can
evaluate a design through virtual mock-ups, which is much
less costly than traditional mock-ups. These VR simulations
have industrial applications either in the design (for
example, a car dashboard) or in the manufacturing processes
(to evaluate safety, operability or maintainability of a
production line). All applications share the need for an
articulated virtual manikin controlled by a set of motion
capture devices placed on a human subject. These
applications allow a "virtual immersion" where the
goal is to recreate the "look and feel" of a
complete environment with accuracy.

introduction of human factors into the design process
- Improve accommodation of
target population
- Reduce the number of
physical prototypes

Status
The sales
information on SAFEWORK®Prosuch as pricing,
appropriate products and services, etc. is available through
SAFEWORK Web site.
SAFEWORK®Pro's detailed human models can be
generated and used in Demia's manufacturing simulation
programs. Likewise, integrated product design solution,
CATIA V5 R6, will allow users to combine the superior human
modeling capabilities of SAFEWORK®Pro with the CATIA product design tools to provide total design lifecycle
human modeling.

Barriers
-
It is
difficult to estimate quantitative benefit of SAFEWORK
application in actual construction projects due to the
characteristics of safety.
-
While SAFEWORK has been applied to many manufacturing
processes, there is not an actual application case in
construction area. The development of detailed methodology
of application in construction operations should be
followed.
