“…Dynamic tests carried out by means of standard equipment for modal testing have made it possible to identify the torsion and bending components of swingarm stiffness and to evaluate swingarm damping. There are very few data about swingarm stiffness in the literature, the stiffness values identified in the present research are in agreement with the ones reported by other authors [1] [18] [19] [20] and, as predictable, larger than the ones of scooters [10].…”

This paper focuses on the effect of swingarm deformability on motorcycle stability and in particular on the weave mode. Multibody models for the analysis of stability and handling of single track vehicles require a lumped element representation of the deformability of the critical structural elements of the vehicle. The twist axis method is used to identify lumped stiffness and damping elements able to represent bending and torsion deformability of the swingarm. Experimental tests and identification results dealing with two different swingarms are presented. The identified lumped stiffness and damping elements are implemented in a multibody code and some numerical stability analyses are carried out. Calculated results show that swingarm deformability has a small effect on the stability of super sport motorcycles, whereas the stability of the weave mode of enduro motorcycles is affected by swingarm deformability in a specific range of speeds.

“…Las propiedades mecánicas de un material son las que se encuentran relacionadas cuando el elemento se somete a esfuerzo, además de la importancia de la utilización de materiales compuestos (Airoldi, A., Bertoli, S., Lanzi, L., Sirna, M., y Sala, G., 2012). En esta investigación para la elaboración de simulaciones se va a trabajar con los valores observados en la Tabla 4, son las caracteísticas mesurables capaces de calificar un comportamiento o una respuesta del mismo a situaciones externas, independientemente del tamaño y la geometría del elemento considerado.…”

En este estudio se implementó una técnica de optimización topológica en el bastidor de una motocicleta de competencia Honda CRF 230, con el objetivo de reducir el peso del componente original manteniendo los límites de seguridad de las propiedades mecánicas del material, para obtener un mayor rendimiento del motor y mayor maniobrabilidad para el piloto en una competencia. Para ello, se efectuó la caracterización del material original del chasis de la motocicleta mediante un procedimiento llamado Espectrometría de Chispa, además se realizó el análisis estático del chasis para determinar las condiciones de frontera para la simulación. Para el desarrollar el CAD del chasis y la simulación se utilizó el SolidWorks Simulation. La aplicación de la optimización topológica se realizó utilizando un criterio de distribución de esfuerzos, por medio de la utilización del método de MEF. Finalmente, se analizó la estructura original frente a la modificada para obtener como resultado una reducción del 67.6 % de peso del chasis original, con un factor de seguridad de 1.41.

“…As mentioned, swingarm structural behavior is the main topic covered in this research. Based on related literature there are several publications focused on swingarm structural analysis, but they all explore single-sided [10][11][12][13][14] or double-sided [15][16][17] rear swingarms. Double-sided swingarms hold the rear wheel by both sides of its axle, while single-sided ones are a type of swingarm which lies along only one side of the rear wheel and hold it in one side, allowing it to be mounted like a car wheel.…”

Design and Structural Analysis of a Front Single-Sided Swingarm for an Electric Three-Wheel Motorcycle

2020

View full text Add to dashboard Cite

This study focuses on the structural analysis of the front single-sided swingarm of a new three-wheel electric motorcycle, recently designed to meet the challenges of the vehicle electrification era. The primary target is to develop a swingarm capable of withstanding the forces applied during motorcycle’s operation and, at the same time, to be as lightweight as possible. Different scenarios of force loadings are considered and emphasis is given to braking forces in emergency braking conditions where higher loads are applied to the front wheels of the vehicle. A dedicated Computer Aided Engineering (CAE) software is used for the structural evaluation of different swingarm designs, through a series of finite element analysis simulations. A topology optimization procedure is also implemented to assist the redesign effort and reduce the weight of the final design. Simulation results in the worst-case loading conditions, indicate strongly that the proposed structure is effective and promising for actual prototyping. A direct comparison of results for the initial and final swingarm design revealed that a 23.2% weight reduction was achieved.
