HVE, HVE-2D & HVE-CSI Version 9 - Now Available
(updated April 23, 2012)

Status of Version 9.00
- - Now Available

Release Date - - April 20, 2012

The list of new features, enhancements and capabilities found in Version 9 includes:

DyMESH Version 3 Wheel Impact

DyMESH Version 3 computes the collision forces and moments for wheel-to-sprung mass and wheel-to-wheel impacts. The model is rigorous, that is, each wheel is a DyMESH object with a mass and a mesh (just like a vehicle). Its properties are defined by the tire dimensions, inertias and radial stiffness. The kinematics of the tire are included, so spinning wheels create moments and forces from tangential friction. Wheel steer and camber are also accounted for. The resulting forces and moments go directly into the equations of motion. Those forces and moments may also produce wheel displacement (linear, camber and steer), directly simulating wheel/suspension damage. Applications include Monster Truck simulations, trailer under-ride resulting in wheel impact, and, of course, the typical intersection collision wherein a wheel represents a hard region affecting collision dynamics.

DyMESH Version 3 3-D Stiffness Coefficients

DyMESH Version 3 uses 3-dimensional stiffness coefficients that employ a 3rd-order force vs. displacement relationship with crush saturation. The enhanced Vehicle Exterior Stiffness dialog provides a Type selector to choose between editing the 2-D or the new 3-D stiffness modeling behavior. Individual coefficients are tuned with a user-editable Conversion Height that relates the existing A,B to the new A,B,C,D coefficients for the cubic equation representing Force vs. Crush. Additionally, the user may adjust Saturation and Maximum Crush values to further define the properties of their specific vehicle.

High-Definition Video Output

The Playback Window, used for creating simulation movies, has been redesigned and is now called the Video Creator. Users can take advantage of new off-screen rendering capabilities to produce movies in standard (640x480), DVD (720x480) and high definition HD (1280x720 and 1920x1080) AVI formats. Improvements also include the ability to control the recording speed frame rate to produce slow-motion movies directly in the Video Creator.

HVE Driver Model Path Visualization

The path that the HVE Driver Model attempts to follow is now visualized directly in the event. Once the user establishes the attempted path by placing targets at key positions, the attempted path calculated by the spline algorithm is displayed as a dotted line.

Current Preferences Settings Display

The current settings for Units, Vehicle Dimension Basis, Auto Backup and Keyboard Settings are now displayed in the lower right corner of the program window.

HVE Brake Designer Stroke Factor

The HVE Brake Designer for S-Cam brakes now includes a Stroke Factor vs. Stroke table, replacing the original, bi-linear method. The resulting table allows the user to more accurately reflect the actual Stroke Factor vs. Stroke relationship for their vehicle's S-Cam brakes.

Dynamic Report Scrolling

All alpha-numeric output reports (e.g., Vehicle Data, Event Data), including the Variable Output table, now scroll dynamically when the vertical scrollbar is dragged. If properly enabled, the scoll wheel on a 3-button mouse may also be used.

2-D Suspension Modeling

The Lateral Load Transfer Coefficients are now displayed. Editing these values allows control over Roll-Couple Distribution inputs used by 2-D physics models, such as EDSVS, EDVTS and EDSMAC4.

Steady State Vehicle Handling Properties Report

The user can now easily display the selected vehicle's handling properties for Total Understeer Gradient, Steering Wheel Sensitivity, Roll Gradient, Roll Couple Distribution, Weight Distribution and Static Weight on Front and Rear Tires, directly in the Vehicle Editor using the new Handling menu option.

Environment Data Terrain Properties Report

The Environment Data output report now includes a table of terrain data for each type of surface (Road, Friction Zone, Curb, Water). Each table includes the number of polygons, the friction multiplier, and the size of the region. The new Environment Data output report also includes the Environment Name, Time, Date and Terrain Filename.

Additional Vehicles Included in the EDVDB Vehicle Database

The custom vehicle database now includes:

2010-2011 Ford Fusion SE
2010 Mercury Milan
2000-2005 Ford Excursion
2007-2011 Toyota Camry LE
2001-2007 Toyota Highlander
