Produktinformationen
Optimization
Designing and producing an innovative product that meets its performance criteria is a goal of every manufacturer. Using optimization techniques, an engineer can improve a proposed design, resulting in the best possible product for minimum cost. Because your designs may have hundreds of variable parameters, with complex inter-relationships, finding an optimal design through manual iterations is hit-or-miss at best. NXT Nastran® – Optimization software relieves the burden involved in improving product designs by automating the iterative process of comparing your design’s performance against its performance specifications.
Benefits through optimization techniques
- Reduce design risk by better understanding the complex relationships among design parameters and how design changes affect these relationships
- Improve confidence that your product will perform to specifications under a variety of operating conditions and manufacturing tolerances
- Accelerate innovation by determining feasible new designs that satisfy all design requirements
- Shorten time-to-market by automating thousands of simulations that would otherwise have to be performed manually
Rotor Dynamics
Rotating systems are subject to gyroscopic forces such as Coriolis and centrifugal forces that are not present in stationary systems. NX Nastran® Rotor Dynamics software provides the capability to predict the dynamic behavior of rotating systems. With the Rotor Dynamics functionality now integrated into NX Nastran, users can now more easily simulate rotating system loads, perform synchronous and asynchronous analysis to generate Campbell Diagram data, predict whirl frequencies and critical speeds and detect instability in rotating components.
Benefits
- Rapidly evaluate and improve the dynamic performance of rotating systems prior to physical prototyping and production commit
- Troubleshoot dynamicsrelated noise and vibration problems in previous designs as well as current in-production rotating equipment systems
- Evaluate and develop optimal in-service design modifications to increase production process throughput of rotating equipment systems
- Evaluate rotor imbalance and study general excitation response
- Compute critical speeds and whirl frequencies from Campbell diagrams
- Evaluate in-flight maneuvering loads on an engine rotor and simulate engine blade-out conditions
- Perform multi-disciplinary structural design analysis and optimization within the unified NX Advanced Simulation environment leveraging NX integration capabilities and using a single common CAE interface
Superelements
Despite the ever-increasing power of computers, finite element models are continuing to get larger, which means that finite element analysis (FEA) solutions can require hours of compute time. NX Nastran® software solves large systems of equations efficiently using sparse matrix algorithms; however, NX Nastran – Superelements offers still greater efficiency. Superelements, an add-on to NX Nastran – Basic, plays a key role when solving very large and complex finite element models by decomposing larger structures into equivalent sets of smaller substructures called superelements. NX Nastran – Superelements can be used with all NX Nastran analysis capabilities; is particularly efficient in large, full-system analysis such as an entire aircraft, vehicle or ship; and performs incremental and partial assembly solutions.
Benefits
- Accelerate innovation through enhanced solution efficiency
- Reduce product design risk through the ability to perform more iterations
- Enable enterprise-wide collaboration by combining models from different sources (internal and external) and masking proprietary data
- Maximize output of precious computing resources; reduce the amount of memory and disk space required
Advanced Nonlinear
The NX Nastran® Advanced Nonlinear software solution enables you to analyze models with nonlinearity from contacting parts, material nonlinearities and/or geometric nonlinearities (that is, large deformations). An add-on module of NX Nastran – Basic, the Advanced Nonlinear solver is an integration of the well-known and highly regarded ADINA solver into NX Nastran as Solution 601 for implicit solutions or Solution 701 for explicit solutions.
Benefits through Advanced Nonlinear software solution
- Reduce design risk by using simulation to save time and cost compared to physical build-and-break test cycles
- Accelerate your innovation through rapid iteration and numerous “what-if” studies
- Use the same models already built and analyzed linearly with NX Nastran – Basic
- Improve confidence in final designs by virtually investigating your product’s performance under all possible operating conditions
- Obtain more accurate solution results than linear analysis when standard linear assumptions are not valid
Aeroelasticity
Aeroelastic analysis is a capability that enables the analysis of structural models in the presence of an airstream. With NX Nastran® – Aeroelasticity, an optional add-on module to NX Nastran – Basic software, you have access to static aeroelastic capabilities for stress, load, aerodynamic and control system analysis and design using a common finite element representation. As such, it is applicable in the design of airplanes, helicopters, missiles, suspension bridges and even tall chimneys and power lines.
Benefits through Aeroelasticity software solution
- Saves time and money by leveraging existing finite element models from NX Nastran – Basic
- Takes advantage of convenient modeling available with dynamic loads applied in the time or frequency domains
- Saves time by using an automated restart capability to independently investigate changes in structural or aerodynamic models
- Improves user confidence by avoiding undesirable aeroelastic behavior, such as flutter
Direct Matrix Abstraction Program (DMAP)
NX Nastran® – Direct Matrix Abstraction Program (DMAP) software is a unique Nastran programming capability available as an add-on to NX Nastran – Basic that allows users to expand NX Nastran capabilities by writing their own applications and installing their own custom modules. DMAP can be used to compute additional measures of structural response; to transfer intermediate data to and from NX Nastran (for example, externally generated system matrices); to incorporate the latest software enhancements without waiting for a major software release; or to access more than just the standard results output sets.
Benefits through DMAP software solution
- Capture corporate knowledge by implementing industry (or company) specific procedures based on NX Nastran
- Extend the value of your investment by accessing applications that are not part of the the standard NX Nastran solution sequences, such as rotor dynamic, coupling with mechanical system simulation and integration of test and analysis results
- Accelerate digital simulation work by building customized pre- and post-processing applications tailored around NX Nastran
- Always leverage the latest enhancements to NX Nastran by installing and running updates
Dynamic Response
NXT Nastran® – Dynamic Response software enables you to calculate your product’s forced dynamic response to inputs (loads or motions) that vary with time or frequency. An add-on option to NX Nastran – Basic, it complements the linear static and mode solution capabilities found in the Basic solution. Dynamic response capabilities play a key role in various industries such as assessing passenger comfort in aircraft and automobiles under different operating conditions; determining whether engine frequencies or tire excitations from the road suface will adversely affect responses at other areas of a vehicle, such as at the steering column or in the seats; or evaluating the effect of vibrations on the performance of consumer products and other high-tech electronic devices.
Benefits through Dynamic Response software solution
- Reduce your risk by using simulation to save time and cost compared to physical build-and-break test cyclesy
- Accelerate innovation through rapid iteration and numerous “what-if” studies
- Improve confidence in final design by virtually investigating the product’s performance under all possible operating conditions
