The TruckScience Axle Weight Calculator now calculates overall vertical center of gravity of rigid vehicles.

Centre of gravity height calculation rigid tanker ECE-R111

Vertical centers of gravity for body, payload and overall are indicated on the drawing

FMVSS 105 and CMVSS 105

Combined vertical centers of gravity of completed vehicles must be stipulated on Incomplete Vehicle Documents (IVD) in U.S. AND CANADA, to comply with Federal Motor Vehicle Safety Standards (FMVSS 105) and Canada Motor Vehicle Safety Standards (CMVSS 105), “HYDRAULIC BRAKE COMPLIANCE GUIDELINES FOR ALTERED VEHICLES”.

ECE-R111

An overall centre of gravity height calculation is required in order to verify rollover stability of vehicles to the UN’s ECE-R111.  ECE Regulation No. 111 is a European Agreement concerning the International Carriage of Dangerous Goods by Road (ADR), and came into force on 28 December 2000.

ESC Systems

Even in markets where there is no legal requirement to calculate vertical centre of gravity height, it is necessary to do this calculation in order to configure settings for electronic stability control systems of vehicles with a higher center of gravity.

Calculating the Overall Vertical Center of Gravity

The combined center of gravity calculation takes into account the weights, centers of gravity and positions of all equipment that is added to the base vehicle which may affect the vertical center of gravity of the complete vehicle.

The result is then compared to the allowable center of gravity for the completed vehicle, as defined by the vehicle manufacturer.
