CAE
Computer-Aided Engineering
WhiteLight Design and
its associates have invested in keeping pace with the latest available
CAE
Computer-Aided Engineering
predictive analysis, software programs and
hardware platforms. CAE is the use of CAD information such
as 3D virtual models for supporting Engineers in tasks such as design
validation, structural analysis, dynamic simulation, complex assembly
design and manufacturing automation, including planning, diagnosis,
troubleshooting and repair. CAE software tools can analyze the
composition, robustness and performance of materials, components and
assemblies. It can provide virtual simulation, validation
and optimization of products and manufacturing tooling data which is then
compared against the real world to continually build a data base of
predicable materials and dynamic simulation properties.
CAE allows you to maximize design confidence, reduce need for expensive
prototypes and compress the development cycle time.
CAE areas covered include:
- Mechanical Stress analysis on components and assemblies using FEA
(Finite Element Analysis)
- Thermal and Fluid Flow analysis Computational Fluid Dynamics (CFD)
- Kinematics; (Motion Analysis)
- Mechanical event simulation (MES)
- Analysis tools for process simulation for operations such as
casting, molding, and die press forming.
- Optimization of the product or process, earlier in the development
process.
Two primary programs used in CAE are
Pro/ENGINEER (referred to as ProE) (www.ptc.com),
and SolidWorks.
Both are standard in the CAD / CAE industry.
ProEngineer®
/ ProE®
(3D/CAD – CAE modeling program)
Pro/ENGINEER
Commonly
referred to as Pro/E or ProE by Parametric Technology
Corporation (PTC), is a globally accepted standard in the
industry. It is 3D parametric feature solid
modeling software with outputs consisting of solid model data for, CAE /
and finite element analysis,
Pro/ENGINEER CAE Modules:
Mechanism Dynamics (Pro/E Mechanism
Dynamic
Virtually simulate dynamic reactions to accelerations and the weight
of moving components. Simulate reactions to accelerations and the weight
of moving components such as springs, motors, friction, and gravity.
Systems Simulation (Pro/E Advanced
Mechanica)
Simulate real-world performance with an expanded
set of analysis capabilities including:
- Non-linear displacement, pre-stress, dynamic, and transient
thermal analysis
- Materials behaviors such as anisotropic, orthotropic, and
composite laminates
- Force loading - mass/spring/fastener calculations
- Assembly, servicing, workflow analysis
Behavioral Modeling
(Pro/E Behavioral Modeling)
Embed real-world parameters for digital model simulation. Reduce product development costs due to wasted material, excessive shipping
expense, and poor product performance including solving complex
mechanical system - involving diverse specifications and criteria.
Behavioral modeling allows engineers to cost effectively assess effects
of change on design objectives and conduct experimental design studies.
Failure - Fatigue Analysis
(ProE Fatigue Advisor)
Predict and improve the fatigue performance of their designs such as
predicting service life, damage and factor of safety including
durability characteristics to optimize for product life. The goal
is to improve product quality, reduce product failure, warranty
expenses, and avoid costly product recalls.
Mechanical Systems Simulation (Pro/E Mechanica)
Used to gain early product insight and delivers higher quality products
at lower cost with standard analysis types, including linear static,
modal, buckling, contact and steady state thermal. Used to obtain
real-world performance data by directly applying conditions to design
geometry without requiring data translation and simulating results of
design variations.
SolidWorks® (3D/CAD – CAE modeling)
SolidWorks
a subsidiary of
Dassault Systèmes, S.
A. (Suresnes,
France),
is a 3D mechanical parametric feature-based solid modeler, using
the parasolid geometric modeling kernel. SolidWorks employs the
parametric, feature-based approach to creating models and assemblies.
Computational Fluid Dynamics (Flow Analysis)
Other programs include
(Computational Fluid Dynamics) for Flow Analysis and Simulation
for flow analysis and fluid simulation. Used in a wide array
of applications including the medical industry, a HVAC, Electronic
Enclosures thermal cooling system, Valve/Regulator, Medical,
Electronics, HVAC, Automotive, Defense, Aerospace, Oil and Gas, Plastic
Extrusion and Food Processing.
Kinematics; (Motion Analysis)
Kinematics; (Motion Analysis)
<used in simulating motion and performance of part assemblies.
Used for sizing motors/actuators, power consumption, mechanical
linkages, cams, gear drives, springs/dampers, and determine how
contacting parts behave. Motion simulation and analysis is a
quantitative reduction in physical prototyping costs providing
qualitative benefits so more designs can be evaluated, with risk reduction and the
availability of valuable information prior to tooling or prototype
investment.
Electromagnetic System Design Simulation
A 3D electromagnetic field simulator that
allows electrical and electronic designers to simulate the effect of
components exposed to and electromagnetic currents and fields.
Parameters include evaluation of shielding and insulation
requirements. May be used for electromagnetic simulations from motors,
alternators, sensors, actuators, power generators and transformer
systems to micro and macro electro-mechanical systems. Used to simulate
low-frequency electric currents and electric fields in conductive and
capacitive systems and magnetic fields resulting from currents or
permanent magnets, including static, transient and harmonic
low-frequency electromagnetic analysis and simulation of electrostatic,
electromagnetic, circuit and current conduction. Includes
electromagnetic design simulation for force, torque, inductance,
impedance, capacitance, Joule losses, field leakage, saturation, and
electric and magnetic field strengths.

Tolerance Analysis
(dimensional stack-up validation)
Verifying dimensioning and tolerance schemes is an important part of
mechanical of complex assembles to ensure proper fit and function.
Maximum/ and minimum tolerances are calculated to define which
features and tolerances have the greatest impact on the mechanical
stack-up. Tightening tolerance where need and loosing others
that are not critical to design performance.
