Full vehicle NVH represents the most sophisticated form of NVH analysis, with many important benefits.
NVH Director offers the following features for modularized management of vehicle subsystems.
OptiStruct offers many features that reduce solution time and simulation complexities.
A big challenge in full vehicle NVH simulation is handling large size finite element models.
NVH analysis is a special form of physical analysis where the understanding of motion, energy and force transfer are the primary means of root cause identification and problem solving.
The Assembly Browser is an object oriented modeling environment where the fundamental entity is the module entity.
Allows symmetric creation of LP Modules, Connections and dynamic LCS.
Allows you to change the assembly hierarchy by cutting or pasting the modules.
Set parent modules with CMS SE representation in H3D format to be used for analysis in lieu of child module representations when rolled up, or use the child representations when rolled down.
Select and define a set of modules as the subsystem used for analysis.
To manage any of the modules shown in the Assembly Browser, right-click on a module and select Edit Representations. This opens the Edit Module tab, and the Representation sub-tab is shown.
Create assembly hierarchy and assign ID ranges to the modules from external .csv files.
Reduces the amount of manual work involved in preparing a large number of modules by batch.
Allows automated mapping/creation of tagpoints and connections between data from different sources.
Connections can be created using the Create Connection-Interactive and Create Connection-Automatic tools.
Once the connections have been created, use the Connector Browser to review the connections.
Connections can be managed by right-clicking on a connector in the Connector Browser and selecting Edit Connection.
Use this tool for connection, property and hardpoint mapping.
Use the Connection Realization tool for realization of selected connections based on the specified Tolerance, Property state and State rule.
Allows you to manage local coordinate systems created in the Assembly framework.
Create defined response points that will be automatically used in setting up output requests in NVH analysis.
Create standard analysis frequency sets that will be automatically used in setting up analysis frequencies in NVH analysis.
Create and handle tire modules in different formats, such as CDtire and modal model.
Create defined control volumes that will be automatically used in setting up Transfer Path Analysis diagnostic output in NVH analysis.
Create panel sets by selecting nodes/elements and/or existing node sets in the model file, that will automatically be used in setting up Panel Participation diagnostic output in NVH analysis.
In a real-life application, necessary preparation work needs to be done to get the module representation files to a state that is ready for assembly. Use the Prepare Module tool to accomplish this goal.
Edit and test NVH templates used for creating lumped parameter (LP) models, multiple instances of one model transformed to a new geometric location, or loadcases.
An Analysis is a collection of module, connection and loadcase selections that completely specifies the assembly definition for a particular simulation event.
Reduce the amount of manual work involved in performing a normal modes run to check out multiple modules by batch processing.
Reduce the amount of manual work involved in generating CMS superelements or CDS superelements for multiple modules by batch processing.
Job Manager is designed to provide a way to interact with analysis jobs created through the NVH Director.
The network view is a block diagram view emphasizing inter-connectivity of the assembly.
Allows for quick comparison of master solver decks generated from the Analysis Manager or existing master solver decks.
Allows automatic mapping of modified and/or missing file paths and folders in the .xml file.
Package all project data (Assembly .xml files, Representation files, LP Templates, Loadcase files, Job files and CSV templates) for transfer to others or for archival.
Create standard tuning sets that can be used in the Analysis Manager for automatically setting up quick modification runs in NVH analysis.
The Crash application offers a tailored environment in HyperWorks that efficiently steers the Crash CAE specialist in CAE model building, starting from CAD geometry and finishing with a runnable solver deck in Radioss, LS-DYNA and PAM-CRASH 2G.
HyperWorks offers high quality tools for CFD applications enabling the engineer to perform modeling, optimization and post-processing tasks efficiently.
The Drop Test Manager is an automated solution that allows you to either simulate a single drop test or a choice of multiple iterations with the aim of finding the sensitivity of process variables like initial orientation and drop height in a typical drop test by controlling the run parameters and conditions with ease.
Many essential utility tools using HyperWorks-Tcl have been developed over the years to support Aerospace customers. A few tools have been collected and upgraded to be compatible with this release.
