Manoeuvrability increases as the inertia moment decreases, whereas driving stability when the vehicle is moving in a straight line and on S bends decreases by the same amount. In addition to the type of drive, the vehicle’s moment of inertia J Z, V around the vertical axis is the determining factor for its cornering performance. The position of its centre of gravity and the variables of the moment of inertia are usually determined with the basic design of a vehicle (drive, wheelbase, dimensions and weight). In addition to this, in general, the inertia moments of power units (engine-gear-box unit) and individual rotationally symmetrical elements, such as steering wheels, tyred wheels, etc. The body moment of inertia J Y,B,o around the transverse axis ( y-axis) is the determining variable for calculating pitch vibration behaviour. The body moment of inertia J X,B,o around the vehicle’s longitudinal axis ( x-axis) is essential for generally studying body movement (roll behaviour) during fast lane changes in the driving direction. Moment of inertia for I section can be built using 3 rectangles, and similarly many shapes can be built using basic shapes. The area moment of inertia can be found about an axis which is at origin or about an axis defined by the user. 3.3) is required for driving stability studies or even for reconstructing road traffic accidents. Find moment of inertia for I section, rectangle, circle, triangle and various different shapes. The vehicle moment of inertia J Z, V around the vertical axis ( z-axis, Fig.
