New design of a road profiler

Macro and micro road profiles are of significant importance for vehicular motion studies, reliable calculations of vehicle system properties, and ensuring vehicular safety. As such, road profiles should be considered carefully. Macro profiles consider the spatial geometry of the road (curves, longitudinal and lateral slopes) while micro profiles consider roughness in longitudinal and lateral directions. These profiles have random characteristics that can be quantified under onroad and off-road conditions using a road profiler. This paper presents an analysis of a new concept for a universal profiler without gyroscopic stabilizers

A method of vehicle active suspension design

This paper contributes to the design of active suspension systems, by the use of spatial vehicle model, without filtered feedback of the control system. A method of stochastic parameters optimisation has been utilized for the optimisation of the parameters of active suspension. The optimisation objective was simultaneous minimization of sprung mass vibration and standard deviation of forces in tire-to-ground contact area and vehicle handling
