MSC Software's Adams 2014 Delivers Higher Fidelity and Ease of Use with Native Nonlinear and Coupled FE Technologies
NEWPORT BEACH, Calif. --(Business Wire)--
MSC
Software Corporation, a global leader in helping product
manufacturers advance their engineering methods with simulation software
and services, today announced the upcoming release of Adams
2014.
Efficiently designing and testing mechanical systems is a challenge for
some engineers due to lack of smooth integration between system dynamics
and finite element analysis (FEA) software domains. The Adams 2014
release addresses this issue by introducing new native nonlinear part
modeling and analysis, and co-simulation between Adams
and Marc
nonlinear finite element analysis. Adams 2014 also extends popular
machinery and automotive industry solutions with the new Cam module in
Adams/Machinery and extended vehicle modeling and rollover events in
Adams/Car.
Highlights of this release include:
-
New Adams Native Nonlinear Part Modeling and Analysis
The
FE Part is a new Adams-native modeling object for very large
deformation use cases, and specifically considers geometric
nonlinearity. The formulation options are based on MSC (News - Alert) adaptations of
the Absolute Nodal Coordinate Formulation (ANCF) and Geometrically
Exact Beam Formulation (GEBF). Engineers can more accurately calculate
dynamic loads for geometrically nonlinear parts within a multibody
dynamic system. The FE Part offers a 3D Beam formulation option, a
three-dimensional, fully geometrically nonlinear representation useful
for beam-like structures; a basic two-dimensional option is available
as well. Adams/View supports the creation, visualization, and
modification of FE Parts, as well as the convenient application of
distributed loads via the new FE Load. In some benchmark test cases,
modeling time was reduced from 8 hours to 30 minutes.
"The new Adams nonlinear beam implementation is a great feature that
makes it much easier to add nonlinear compliance and contact bhaviors
to the model, without affecting simulation times. Used creatively, the
beam element can represent a variety of situations that previously
required flex body generation and/or multi-component part
representation, saving time and making parameterization easier,"
said Joseph Little, Virtual Tools Engineer at Chrysler Group.

New Full Co-simulation Support for Adams and Marc
The
Adams-Marc co-simulation capability enables users to perform real
co-simulation between Adams and Marc nonlinear FEA software. By doing
so, multibody dynamics engineers working with Adams can increase model
accuracy by including geometrically and materially nonlinear
structural behavior, and FEA engineers can study components with
realistic boundary conditions.
The co-simulation delivers
dramatic time savings for nonlinear FEA users because some of the
rigid moving parts can be simulated in Adams instead of the FEA
environment; this drives the total solution time down dramatically.
"The Adams-Marc co-simulation capability more than satisfies our
guideline of 'reasonable results in a reasonable time.' With up to a 90%
reduction in computation time, optimization using advanced nonlinear FEA
becomes practical. Such development provides a great benefit and is
crucial for our product development," said Dr. Steve Jia,
Chief Engineer, Litens Automotive Group.

New Cam Module in Adams/Machinery
Optimizing cam-follower
systems early in the design process is key to saving cost and
improving product performance. The new Adams/Machinery
Cam module provides easy-to-use modeling of cam-follower systems.
These systems may comprise various combinations of cam shapes,
follower motions, follower arrangements, and follower geometry. The
new feature makes Cam model creation much faster. It is easier to make
mechanism motion and Cam profile design changes, and optimize the
motion function to minimize or maximize acceleration, for instance.

New Vehicle Modeling Enhancements in Adams/Car
New
Stability Events in Adams/Car Rollover accidents can cause
fatalities. To provide better occupant protection, the study of
rollover motion and vehicle stability is crucial. Adams/Car
now provides three new rollover stability test events, including
Embankment, Corkscrew, and Sand Bed.
FTire Animation Higher-fidelity
analysis and visualization are needed for vehicle ride events like
tires rolling over various surfaces. FTire contact forces and tire
deformation forces can now be animated within Adams/PostProcessor.
SmartDriver
Enhancements Vehicle performance and handling tests continue
to evolve, and so does the need to virtually model and simulate these
events virtually. To address this challenge, a number of enhancements
to SmartDriver have been introduced. Improved backwards driving for
open loop events is supported for both simple and automatic
powertrains. Other noteworthy features include additional speed
profile spline interpolation improvements, providing continuous target
acceleration and smoother throttle and brake signals.
