Abstract

A vehicle model is developed employing a detailed nonlinear kinematic representation of a MacPherson strut front independent automotive suspension with a rack and pinion steering system. The vehicle model is capable of front wheel steering motions as well as vehicle body rolling motions. The vehicle model is used to simulate steady-state turning maneuvers on a smooth, flat road. The model is employed in conjunction with a realistic set of constraints to optimize a representative suspension and steering system with respect to steering error for turn radii and body roll angles typical of highway driving. Improved suspension and steering geometries are presented for two optimization studies.

Zusammenfassung

Es wird ein Fahrzeugmodell entwickelt, das auf einer ausführlichen kinematischen Beschreibung der MacPherson-Vorderradaufhüngung mit einer Zahnstangen-Ritzel-Lenkung basiert. Dieses Fahrzeugmodell ermöglicht Vorderradlenk- sowie Fahrzeugrollbewegungen. Das Modell wird benutzt, um gleichmäβige Lenkmanöver auf glatten, ebenen Straβen zu simulieren. Das Modell wird ferner benutzt, um unter realen Bedingungen ein typisches Aufhänge- und Lenksystem in Bezug auf die Lenkabweichung für Kurvenradien und Fahrzeugrollwinkel bei Autobahnfahrten zu optimieren. Verbesserte Aufhänge- und Lenkungsgeometrie werden für zwei Optimierungs-studien dargestellt.

Kinematic and sensitivity analysis and optimization of planar rack-and-pinion steering linkages
2009, Mechanism and Machine Theory
In this paper, the combined kinematic and sensitivity optimization of a rack-and-pinion steering linkage is performed. This steering linkage is the most common steering system used in passenger cars. Although, the steering linkage has received a lot of attention for the minimization of the steering errors, no attempt has been made so far to investigate the sensitivities of optimum dimensions relative to variation of link lengths. The kinematic optimization of the linkage is carried out using three homogenous design parameters. The objective of the proposed optimization is to minimize maximum steering error during cornering. This is followed by a sensitivity analysis to predict how the steering error is affected by manufacturing tolerances, assembly errors, and clearances resulting due to wear. Since the optimized kinematic error is very sensitive to the variations of the linkage parameters, the kinematic and post-optimal sensitivity optimization of the steering linkage is performed in an integrated manner. The methodology proposed in this work helps the designers of rack-and-pinion steering linkage to choose the linkage parameters whose maximum steering error (MSE) and sensitivity are minimum.
The synthesis of six-bar linkages as constrained planar 3R chains
2008, Mechanism and Machine Theory
In this paper, we constrain a planar serial chain formed by three revolute joints, so that it becomes a one degree-of-freedom six-bar linkage. Our focus is on the various ways that two RR chains can be attached to constrain the links of the 3R chain, and ensure that the end-effector passes through a set of five specified task positions.
This synthesis process yields designs for the Watt I and Stephenson I, II, and III six-bar linkages. This approach does not apply to the Watt II because its floating link is not connected to the ground frame by a 3R chain. We demonstrate the synthesis process with the design of a six-bar steering linkage intended for use on a gravity racer.
Roll steer minimization of McPherson-strut suspension system using genetic algorithm method
2008, Mechanism and Machine Theory
In this research the roll steer of a front McPherson suspension system is studied and the design characteristics of mechanism are optimized using Genetic Algorithm method. The roll steer is defined as undesirable and uncontrollable changes in the steering angle of the steered wheels during the rolling action of the vehicle body due to cornering maneuver or asymmetric bumps. The roll steer affects handling and dynamic stability of the vehicle due to variation of the angles of the wheel and the suspension links (i.e. camber, caster and toe). However these changes cause other problems. In this paper, in conjunction with the study of three-dimensional kinematic model of McPherson mechanism, a set of mathematical equations are derived to determine the suspension behavior of a typical vehicle through the rolling. The kinematic analysis is followed by an optimization process using the genetic algorithm method to determine the optimum length and orientation of the mechanism’s members to minimize the variations of the toe, the camber and the caster angles. However the variations cannot be expressed by closed form functions, thus a performance index is defined in the integral form which expresses the overall variations of the main parameters in the whole range of rolling of the body. It is shown that the genetic algorithm can be effectively used in optimization of three-dimensional behavior of such spatial linkages in which the performances indices have no closed form with many variables under the non-smooth constrains. The presented method not only can be used to design of optimum novel suspension systems, but also to improve the kinematic behavior of existing systems.
