Heavy Truck Suspension Dynamics: Methods for Evaluating Suspension Road Friendliness and Ride Quality

Evaluating heavy truck suspensions for road friendliness and ride quality is a complex challenge An experimental study has been conduced to explore various options for evaluating suspension performance The methods examined use laboratory equipment and focus on evaluating suspension performance without the influence of the whole vehicle The experimental program found that “in phase sinusoidal frequency sweep” of constant amplitude produced clear differentiation of suspension response
