“…The use of ADAMS within the automotive industry to study the behaviour of suspension systems or to simulate the ride and handling performance of a new design is well documented by Orlandea and Chase (1977), Rai and Soloman (1982), Blundell (1991), Antoun et al (1986) and Dorey (1994). A more general review of the role of Multibody Systems Analysis in vehicle design is given in Blundell et al (1996).…”

This paper describes the initial phase of work carried out as part of an on going study investigating the interaction between the tyre, suspension system and an antilock braking system (ABS). The modelling, analysis simulations and integration of results have been performed using an industry standard Multibody Systems Analysis (MBS) program. A quarter vehicle model has been used together with an individual front suspension system represented by interconnected rigid bodies. The tyre model used can be integrated into vehicle handling simulations but only the theory associated with the generation of longitudinal braking forces is described here. An ABS model based on slip control has been used to formulate the braking forces described in this paper. The simulations, which have been performed braking on wet and dry road surfaces, compare the performance of two different tyres.

“…The radial force is dependent on the tyre deflection and its rate of change, both measured along the tyre vertical directional vector. The tyre-damping ratio can be neglected since the product of the velocities in the tyre contact patch and the damping ratio in the tyre was quite low; hence, the vertical force can be computed using equation (2). However, it is advisable for most applications to include the damping contribution to the vertical force…”

“…To ensure rigorous testing of vehicle stability, some severe steered conditions have been reported, for example a 2108 steering ramp within 0.4 s while using a 42 degrees of freedom non-linear multibody model [2]. The exact nature of a manoeuvre has been debated for a long time, culminating in a number of standardized tests embodied in, for example the British Standard or in ISO for the given types of motion such as lane change, slalom, and in cornering [6].…”

This article presents transient handling analysis with a full-vehicle non-linear multi-body dynamic model, having 102 degrees of freedom. A transient cornering manoeuvre, with a constant steer angle and velocity has been undertaken. The effects of aerodynamic lift and drag forces have been included in the simulation tests. The vehicle handling characteristics with and without aerodynamic forces have been compared and various observations made. The aerodynamic forces have been predicted by a k-1 model solution of the Navier-Stokes equations for turbulent flow. The numerical predictions for the evaluation of aerodynamic lift coefficient agrees well with the scaled-down air tunnel experimental work, using hot-wire anemometry.

“…Chace [3] and Orlandea et al [4,5] have investigated a three-dimensional vehicle model with 42 rigid-body degrees of freedom. They subjected their model to a severe steering ramp input of 2108 in 0.4 s while travelling at a forward tangential speed of 75 kmah.…”

This paper presents a multidegrees-of-freedom non-linear multibody dynamic model of a vehicle, comprising front and rear suspensions, steering system, road wheels, tyres and vehicle inertia. The model incorporates all sources of compliance, stiffness and damping, all with non-linear characteristics. The vehicle model is created in ADAMS (automatic dynamic analysis of mechanical systems) formulation. The model is used for the purpose of vehicle handling analysis. Simulation runs, in-line with vehicle manoeuvres specified under ISO and British Standards, have been undertaken and reported in the paper.
