ISO 10392:2011规定了确定道路车辆重心(CG)位置的方法,如ISO 3833所定义。提供了一种确定CG在水平面上坐标的方法。规定了两种确定重心离地高度的方法。
轴升法和稳定摆法是确定车辆重心高度的最常用方法。轴提升法需要较少的专用设备,通常比稳定摆法更简单、成本更低。轴升法通常可以提供几%范围内的重心高度精度,而稳定摆法可以提供0.5%范围内的精度。
ISO 10392:2011 specifies methods for determining the location of the centre of gravity (CG) of a road vehicle, as defined in ISO 3833. A method for determining the coordinates of the CG in the horizontal plane is provided. Two methods for determining the height of the CG above the ground are specified.
The axle lift and the stable pendulum methods are the most common methods for determining vehicle CG height. The axle lift method requires less dedicated equipment and is typically an easier and less expensive method than the stable pendulum method. The axle lift method can generally provide CG height accuracy in the range of a few percent, while the stable pendulum method can provide accuracy in the range of 0,5%.
