Vehicle Tilt Testing

At a glance

Vehicle tilt test is a quasi-static test performed to determine vehicle stability and centre of gravity location. Millbrook tilt tests a wide range of vehicles, including passenger cars, buses, off-highway and military vehicles, cranes, forklifts, and more.

The vehicle tilt test is part of Individual Vehicle Approval (IVA) for buses and coaches, and is part of a legislative requirement for emergency service vehicles, forklift trucks, cranes and more. The tilt test can also be used to classify the mobility of military vehicles, when incorporated with a range of other track based tests.

Millbrook’s tilt table is part of an approved site for ECE R107 and BS EN 1846-2 (fire appliances). Millbrook is able to act as witnessing technical service on behalf of RDW for ECE R107, and there are VCA engineers on site to witness tests for certification.

Tilt Table Specification

The tilt table is able to tilt vehicles to a maximum wheelbase of 8.5m and a maximum width of 2.8m. Longitudinal tilt tests can also be conducted on passenger cars to test oil flow within in an engine when on a steep decline.

Vehicle Tilt Test Data Logging

During the test, Millbrook can measure the tilt table angle at which the vehicle’s wheels on different axles lift, the point of maximum stability, and rollover. During the test, Millbrook is able to log a range of other vehicle parameters, including vehicle body angles in relation to the tilt table, which provide an indication of the amount of body roll. Once the test angles at maximum stability are known, the vehicle’s center of gravity can be calculated.

With a range of available ballast, Millbrook is able to represent seated passengers, wheelchair users, standees, and luggage.
