Tony Robinson, Alf’s assistant is on the right. After Hawthorn was 2nd to Harry Schell in a Vanwall in practice, Francis improved the 250F by dropping the axle ratio and taking a leaf out of the rear spring (DASO 147). Hawthorn then won the race from Schell. This was just after Hawthorn had left Vandervell’s team, dissatisfied with their reliability, and returned to Ferrari for the classic GPs. He and Vandervell had exchanged discourteous gestures as he arrived in the paddock! Colin Chapman showing a masterful elbow at Ramp corner in his Lotus Mk IX with an MG 1½ litre engine.

    ! The Ex-Alan Stacey, Works 1959 Lotus 15 Chassis No. 621-3 Engine No. 1097 • Driven with notable success for Team Lotus by Alan Stacey during the 1959 season. • According to a leading historian to have potentially been taken to Le Mans in 1959 as a spare car or even a second entry. • Sold to New Zealand in 1959 where it continued a well documented and successful racing career on into the 1970’s. • Driven to an impressive 7th in the 1960 New Zealand Grand Prix by Jim Palmer, in the company of Moss, Mclaren and Brabham, all in 2.5-litre Cooper Grand Prix cars. • Re-imported into the UK by respected historic racer and collector Spencer Flack. • Raced with great success by its current owner since 2008, with numerous wins, overall class victory in the Stirling Moss Trophy 2009, 2010 and 2011, 2nd in the Madgwick Cup and a 5th in the Sussex Trophy at the Goodwood Revival and an impressive 2nd overall in the hard fought Plateaux 3 at Peter Auto’s Le Mans Classic. • Meticulously prepared by one of the most respected names in historic racing with no expense spared, having seen little or no miles since its last refresh. • This is an incredibly rare opportunity to acquire such an original and well regarded Ex-Works Lotus and an absolute proven front running ‘50s Sports Car. To many, the 1950s saw sportscar racing at its most pure, establishing and creating some of the most influential car manufacturers for the decades to follow. By the mid to late 1950’s the tides of sports car design were starting to turn and pave the way for things to come.

The investigated model is a full-scale Macpherson which is a multibody system. Two degree of freedom model is considered here to illustrate the vertical displacement of sprung mass and unsprung mass with using displacement matrix. Ride and handling parameters including displacement of sprung and unsprung masses, camber/caster an- gle, and track changes are derived from the relationships. Moreover, geometrical model and equations are validated by Adams/Car software. The kinematic and dynamic re- sults have been compared in both analytical and numerical outputs for verification. The proposed analytical model shows less than 5% differences with a complicated multibody model. Keywords: suspension system, MacPherson, multibody system, ride, camber, caster. 1. Introduction Suspension system is composed of a set of links connecting wheels to the car body. The main duties of the suspension system are isolated car body from road input and keeping wheels on appropriate position. Without suspension system, car body moves drastically and parts of the car will shortly fail due to the shocks imposed by road.

  • Roll Center and Roll Axis
    SUSPENSION SYSTEM Suspension - set of elements connecting wheel axles with vehicles’ body • A vehicle suspension is required to perform effectively under a range of operating conditions including high levels of braking and accelerating, cornering at speed and traversing rough terrain – manoeuvres which are required to be done in comfort and with safety. • Suspension system connects vehicles body with wheel and its tire and allow vertical movement of the wheel in relation to body. • The wheels, through the suspension linkage, must propel, steer, and stop the vehicle, and support the associated forces. Suspension system 1. To provide good ride and handling performance – this requires the suspension to have vertical compliance providing chassis isolation and ensuring that the wheels follow the road profile with very little tire load fluctuation; 2. To ensure that steering control is maintained during maneuvering – this requires the wheels to be maintained in the proper positional attitude with respect to the road surface; 3. To ensure that the vehicle responds favorably to control forces produced by the tires as a result of longitudinal braking and accelerating forces, lateral cornering forces and braking and accelerating torques – this requires the suspension geometry to be designed to resist squat, dive and roll of the vehicle body; 4. To provide isolation from high frequency vibration arising from tire excitation – this requires appropriate isolation in the suspension joints to prevent the transmission of ‘road noise’ to the vehicle body. Types of suspension system • Each spatial body with six degrees of freedom can be constrained with suitable elements – like rod links – to reduce the number of DoF • A suspension system should provide one degree of freedom for the wheel.

  • Chassis & Suspension
    Applications – Chassis & Suspension Introduction The chassis is considered to be one of the significant structures of an automobile. It is the frame which holds both the car body and the power train. Various mechanical parts like the engine and the drive train, the axle assemblies including the wheels, the suspension parts, the brakes, the steering components, etc., are bolted onto the chassis. The chassis provides the strength needed for supporting the different vehicular components as well as the payload and helps to keep the automobile rigid and stiff. Consequently, the chassis is also an important component of the overall safety system. Furthermore, it ensures low levels of noise, vibrations and harshness throughout the automobile. Suspension is the term given to the system of springs, shock absorbers and linkages that connects the vehicle to its wheels. The suspension system serves a dual purpose. It contributes to the car's road performance, the braking characteristics for good active safety and the driving pleasure. It also keeps the vehicle occupants comfortable and reasonably well isolated from road noise, bumps, and vibrations. Chassis design concepts Originally, automobile designs used the body-on-frame construction where a load-bearing chassis consisting of a ladder frame, the powertrain, and the suspension formed the base vehicle which then supported a non-load-bearing body. In the beginning used on almost all vehicles, the ladder frame has been gradually phased out on passenger cars around the 1940s in favor of perimeter frames. In the second half of the last century, the frame chassis design was more and more displaced by monocoque constructions, integrating the body and chassis into a single unit.
