The paper deals with a general method for the multi-criteria optimization of the rear wheels suspension mechanisms in terms of kinematic behavior. The suspension mechanism is decomposed in basic binary links, and the kinematic synthesis is separately performed for each of them. The design variables are the global coordinates of the joint locations on the car body (chassis). The disposing of the joints on the wheel carrier were exclusively established by constructive criteria. The design objectives relate to kinematic position parameters of the wheel (displacements of the wheel centre along longitudinal and transversal directions, and modifications of the wheel axis direction), the optimization goal being to minimize these variations during the wheel travel. A computer program for the kinematic study was developed in C++. The application was performed for the wheel suspension mechanism of a race car.
El artículo se ocupa de un método general para la optimización multiobjetivo de los mecanismos de suspensión de las ruedas posteriores en términos de comportamiento cinemático. El mecanismo de suspensión se descompone en enlaces binarios básicos, y la síntesis cinemática se realizó por separado para cada uno de ellos. Las variables de diseño son las coordenadas globales de las ubicaciones de las articulaciones en el chasis. La disposición de las articulaciones en el soporte de la rueda se estableció exclusivamente por criterios constructivos. Los objetivos de diseño se refieren a la posición de los parámetros cinemáticos de la rueda. El propósito de la optimización consiste en minimizar estas variaciones. Un programa informático para el estudio cinemático fue desarrollado en C ++. La aplicación numérica se llevó a cabo para el mecanismo de suspensión de un vehículo monoplaza.
