Suspension System Modeling and Structural Loading

1975-02-01
750134
The object of this paper is to present an overview of the procedure leading to the selection of suspension system pivot points, show how to resolve terrain and maneuver loads at the tire contact patch to the vehicles' structure, illustrate the modeling technique used for stress analysis of suspension system components, and illustrate a few examples of suspension system models used to aid in the solution of ride and handling problems.

Vehicle to Vehicle Collisions Utilizing Energy Absorbing Units

1975-02-01
750110
This paper presents the possibility of utilizing shock absorbers to decrease the aggresivity of a large car towards a small car at an impact of 40 mph. Reduction of such aggresivity would result in more damage to the large car, thereby reducing the impact on the small car. The conclusions demonstrate a definite decreased aggresivity of the larger car. Increase of the shock stroke does cause the large car to be crushed more in car-to-car collision. However, this occured at speeds below 25 mph, not the 40 mph as set by the study.

CHRYSLER TORSION-AIRE SUSPENSION Across The Board

1958-01-01
580031
IN 1951 Chrysler Corp. began working on a new torsion suspension. In this paper the authors describe details of the development and design of the suspension, now available on 1957 cars. The authors claim the Torsion-Aire suspension has the following advantages: reduced highspeed float, boulevard harshness, impact harshness, road noise, body roll, nose dive, and acceleration squat; better directional stability and cornering ability; fewer lubrication points; and a better balanced ride. The main feature of the front suspension is the use of torsion bars. One of the principal advantages of torsion bars is their weight: 10 lb as compared to 15.8 lb for a 1956 production coil spring.

Chrysler Corporation's Isolated Transverse Torsion Bar Front Suspension

1977-02-01
770179
To satisfy the objectives of Chrysler's new generation of compact vehicles, a unique front suspension system was created. This system has achieved an outstanding level of ride comfort while providing significant advantages in the basic vehicle packaging. The key to the system is the transverse torsion bar and bushings which serve the dual function of suspension spring and fore and aft restraint for the lower control arm. Producing this torsion bar in mass production required advances in both engineering and manufacturing technology.
