Aquaplane is a test plugin pre-loaded into VBOX Test Suite. VBTS Aquaplane allows you to easily obtain results for both longitudinal and lateral aquaplane applications, and gain a greater understanding of the characteristics and behaviour of the tyres under test.

The software has been designed to be simple to operate, whilst still offering maximum flexibility, allowing the user to attain and analyse accurate data.

At the click of a mouse or tap on a screen, the user is able to set the start line, start of bath and end line.

Key Features

Longitudinal

Simple to set-up and use Clear, easy to read pass/fail criteria Produces a customisable report of Entry Speed vs Lateral Acceleration Map integration - overlay a positional trace onto a satellite image Compatible with any VBOX data logger

Video integration No in-depth VBOX knowledge required Automated wheel speed calibration procedure Customisable entry conditions allow the user to ensure the vehicle enters the bath in a steady state

Lateral

Simple to set-up and use Clear, easy to read indication of wheels speeds and percentage slip Map integration - overlay a positional trace onto a satellite image Compatible with any VBOX data logger

Video integration No in-depth VBOX knowledge required Automated wheel speed calibration procedure No external beacons required Manually set line conditions

Longitudinal Aquaplane

The VTS Longitudinal Aquaplane plugin can be used to denote a threshold slip value for each wheel, providing the user with the opportunity to choose between reaching the aquaplane condition when one, or all of the tyres, exheed this value.

It provides the ability to set pre-entry test conditions in order to ensure the vehicle is in a steady state before the test begins, and automatically calibrates wheel speeds simply by driving at a constant speed - removing the restraints of having to calibrate within the test area.

Lateral Aquaplane

As test entry speeds increase, the lateral acceleration obtained will also increase. However, once the vehicle starts to aquaplane the acceleration values start to tail-off.

By closely monitoring the vehicle's lateral acceleration throughout the test procedure, the VTS Lateral Aquaplane plugin produces a comprehensive report outlining in detail the maximum acceleration obtained and how quickly, and to what degree, this value decreases when the tyres begin to aquaplane.

This data can be directly compared to other tyre compounds to provide engineers with the information needed to grade tyre performance in wet corner conditions.
