The Optimize This! 2016 International HEEDS User Conference is fast
approaching. The event will highlight many customers applying HEEDS
design exploration to discover better designs, faster. Below
are a few stories to be presented. Keep reading to learn more about
exciting HEEDS happenings.

Designing for Full Aircraft Engine
Performance
Honeywell
Aerospace uses HEEDS throughout the complete aircraft engine design
process, from preliminary full engine performance design
exploration to detailed component design, as well as calibration of
models to test data.
The full engine performance studies rely on zero-dimensional or
one-dimensional engine performance simulation models. There are
typically many variables and constraints on single or multiple
objectives. The simulations generally run very fast so the design
exploration can accommodate a large number of evaluations. The
detailed component analyses combine one-dimensional simulation
models, for constructing turbine or fan blade geometry, with
three-dimensional simulation models, for detailed flow, stress and
vibration assessment. For all of these Honeywell studies, HEEDS is
used to automatically assemble virtual prototypes from in-house and
commercial simulation software, test these prototypes to predict
performance, and explore the available design space to discover
great designs. Honeywell will present their use cases, successes
and challenges at Optimize This! 2016
Conference on October 12th.

Implementing Multi-Objective
Transmission Design
In an automotive
transmission, rotational mass reduction is critical for the
improvement of fuel economy. However, difficulties in automated
finite element modeling, non-linear analysis of gear contacts and
bearing supports, and limitations of common single objective design
studies create obstacles to identifying required design
improvements. Toyota will present how they successfully used HEEDS
to improve the design of a differential pinion shaft sub-system at
the Optimize This! 2016
Conference on October 12th. The speaker will highlight how the
multiple objectives of mass reduction and gear root stress
minimization were achieved while satisfying numerous constraints
involving fatigue and bearing life.

Light-Weighting an Aluminum Bumper
Beam System
Automotive
front and rear bumper systems are key contributors to the
crashworthiness of any vehicle. They serve not only to absorb
energy, but also to minimize intrusion of foreign objects into the
engine and passenger compartments. For this reason, their design is
highly regulated by governmental safety organizations. Vehicle
manufacturers have the competing challenge of satisfying these
strict crash requirements while also reducing bumper assembly
weight to meet stringent fuel economy mandates. At the upcoming Optimize This! 2016
Conference, Magna Cosma engineers will highlight how they used
HEEDS to automate the process of analyzing bumper variations to
discover the best designs for both weight and crashworthiness.

Meeting Requirements Without
Sacrificing Performance
In
the oil and gas industry, metallic seals are often used to prevent
the movement of fluid in the annular regions between concentric
bodies. These seals may have a cross section in a "U" or
"H" shape with bumps on the "legs" that provide
the sealing surface. These seals must be designed with a
sufficiently low installation load while at the same time must
maintain adequate contact force on both sides of the seal during
operation. Machine tolerance variations create the possibility of
both a most-rigid and least-rigid version of a given nominal seal
design, and the sealing criteria must be maintained for both
scenarios. Tight machining tolerances allow for a less complicated
design process with fewer iterations but are very expensive. HEEDS
is used to optimize the geometry of a U-shaped seal to allow for
looser tolerances and to minimize the annular width while
maintaining installation and sealing design criteria. FMC
Technologies will present this work at the Optimize This! 2016
Conference in October.

The first step in any design exploration study is to
define the way in which the virtual prototype simulation model is
to be constructed and modified. This typically involves identifying
the various modeling and simulation tools that are involved,
specifying where they are executed, choosing the simulation models
that are being modified, selecting the parameters being driven and
monitored, and documenting what outputs are being stored for each
design point. Read

Ron Averill is one
of the founders of Red Cedar Technology and a continuing contributor
to our training programs. Ron takes the time to provide some
thought-provoking ideas on expanding the usage of design exploration.
Using
Constraints to Limit the Range of the Pareto Front
Sometimes we have more than one output response that needs to be
either minimized or maximized, so we need some way to encourage
multiple responses to be as small as possible or as large as possible
at the same time. These are called multi-objective design exploration
problems. Read
