HVE, HVE-2D & HVE-CSI Version 8.1 - Now Available
(updated December 22, 2010)

Status of Version 8.10
- - Now Available

Release Date - - December 20, 2010

The list of new features, enhancements and capabilities found in Version 8.1 includes:

  • DamageStudio® - DamageStudio is a graphical analysis tool available in the HVE Playback Editor, that allows the user to visualize collision data, and to correlate collision damage with the kinetics (force magnitude and direction), delta-V, acceleration and other important collision parameters. DamageStudio is an option that replaces the Damage Profiles output report. DamageStudio and its cousin, CollisionData are described in great detail in the Technical Sessions of the Spring 2010 and Summer 2010 newsletters.

  • Ackermann Steering - The Driver Controls Steer Table dialog now includes an option for Ackermann steering. If selected by clicking the Use Ackermann Steering checkbox, the simulation will calculate the current Ackermann steer angle for the inside and outside wheels of a steerable axle while negotiating a curve.

  • Vehicle Dynamics Properties - Some HVE vehicle simulation models now calculate and display steady state vehicle handling properties in their Vehicle Data output reports. Please refer to the Technical Session of the Fall 2010 newsletter for more information, as it focuses on these properties and how they are calculated.

  • Accelerometers - In addition to local acceleration components, the Key Results Accelerometers output group now reports earth-fixed X, Y, Z coordinates and earth- and vehicle-fixed velocity components.

  • Vehicle Dimensions Basis - The User Preferences dialog in HVE and HVE-2D now includes an option for setting the Vehicle Dimensions Basis to either Sprung Mass or Total Mass. HVE has always used Sprung Mass basis (a requirement for 3-D simulation). However, 2-D calculations use the location of the total mass CG. Total Mass basis is more commonly encountered, since most vehicle measurements reflect the vehicle total weight and do not separate sprung and unsprung masses.

  • File Browsers - All file browsers in Version 8.1 now check the length of the names being used for case files, geometries (vehicle and environment) and images (textures). If the filename (including the extension) exceeds the limit of 30 characters, a message is displayed identifying that you must use a shorter name. This action corrects an issue that has resulted in corrupt case files for some users. Because HVE was not checking the length of the filename, the additional characters could over-write important case file data, resulting in an unreadable case file.

  • AutoSave - The AutoBackup function in the User Preferences dialog has been improved to provide a more robust backup of your case file. Up to 10 temporary backup files of your active case can be created and stored in the Temp folder of the HVE directory. These files are only used in the event of a program crash or to purposefully revert back to a recently saved version of the active case file. Your regular routine of using Save or Save As always creates a proper case file in your selected location, typically your supportFiles/case folder.

  • And Much, Much, More -

These are just a few of the enhancements that are available to users of Version 8.1. More information will be posted as it becomes available.
