The purpose of this degree work is to analyse side force reduction on the upper mount of a McPherson automotive front suspension, assembled on a vehicle. Adams software was used as it allows simulating a vehicle on realistic driving conditions and calculates the forces on a vehicle (points/joints). By changing the inclination of the spring axis with respect to the shock absorber axis, numerous analyses were made considering various driving conditions, all attributable to operations that a driver can access during normal use of the car. Parametric modeling software was used to change the inclination of the spring with respect to the shock absorber, which made it possible to obtain the hypothetical variants, considering the physical limits imposed by the geometry of the suspension itself.
