A desire to improve the positioning accuracy of ball screws prompted an investigation into the dynamics of nanometer motion. Characterization of the ball screw indicated that nanometer motion is… Expand
Reduced-order modelling and parameter estimation for a quarter-car suspension system
Abstract This paper presents a new approach to obtaining an accurate simple model for complex mechanical systems. The methodology is applied to a quarter-car suspension system with complex linkage… Expand
An Accurate Full Car Ride Model Using Model Reducing Techniques
In this study, an approach to obtain an accurate yet simple model for full-vehicle ride analysis is proposed. The approach involves linearization of a full car MBD (multibody dynamics) model to… Expand
Effect of the suspension structure on equivalent suspension parameters
Abstract This paper examines the uncertainties in modelling a real suspension system that are due to the effect of suspension linkage layout (or structure) on the equivalent suspension parameters of… Expand
