Modeling of a pendulum type child travel seat

Abstract

When passengers are in a vehicle travelling round a curve at speed they will be familiar with the reality of the radial inertial force. Experiments have shown that an uncompensated radial (lateral) acceleration in excess of about 0,1g is definitely unpleasant. This acceleration would be attained at about 100 km/h on an 800 m radius curve (a=v2/r). One of solution is the superelevation of the track or road cross slope (virage). In addition to reducing the side thrust on the rails, super elevation tends to ensure that the resultant force due to weight and inertia force is normal to the seat.
