Go-Kart Chassis Design Using Finite Element Analysis and Multibody Dynamic Simulation

Abstract

For the accurate design of some types of mechanisms, it is necessary to combine multibody dynamics computer simulations with finite element structural analysis. These types of mechanisms are the multibody mechanisms in which the body (frame) stiffness of some of the bodies have the same magnitude as some of their elastic elements. With this in mind, the traditional go-kart chassis design process is reviewed. The traditional approach to evaluate the structural properties of its frame consists of an iterative process in which FEM techniques are applied considering constant load cases. These load cases are defined according to the maximum stresses to which it will be subjected during its operation (circulation in a race circuit). However, as it will be proven in this work, the load case will depend on the design of the frame itself. Due to the stiffness of the frame, for the same driving conditions (vehicle trajectory and speed) the structural load condition varies significantly. A design methodology is proposed for this type of system that combines multibody simulation and finite elements.

Shear Lag Effect Study of a Composite Girder Cable-Stayed Bridge During Construction

“…Based on the principle of virtual work, Huang et al [21,22] analysed the influence of the time-varying characteristics of the contact section of old and new concrete on the shear-lag effect in composite beams and reasonably predicted the long-term performance of composite beams, which helps in the life-cycle design and service performance analysis of composite bridges. Sampayo et al [23] analysed the chassis design using finite element analysis and multibody dynamic simulation.…”

Development of a multibody model for go-karts considering frame flexibility

“…Gonçalves [17] researched the comfort and handling optimization of body models by modifying the parameters of the suspension system. Sampayo [18] investigates a coupled simulation methodology in the design of the kart frame, emphasizing the role of frame stiffness due to the lack of a suspension system. The present study also aims to have a validated simulation model.…”

Proposal for the structural design of the three-wheeled vehicle to improve the quality of life of the citizen

“…En el mercado peruano existen tipos de mototaxi, una de ellas es la de la marca BAJAJ, el modelo torito, este modelo fue desarrollado con ingeniería japonesa, en comparación con el otro modelo comercial de mototaxi de las marcas Lifan, Zongshen, Wanxing, etc. Estas se ensamblan de manera empírica, no cuentan con un análisis de ingeniería previa respaldados con cálculos dinámicos, estáticos, estabilidad [9].…”

“…Según [12] en su estudio presenta un nuevo índice de vuelco para triciclos, considerando parámetros como la altura del centro de gravedad del chasis, el freno diferencial en las ruedas traseras, demostrando su eficacia en la predicción y detección del riesgo del vehículo a las volcaduras e incluso de forma estática, el análisis se realizó mediante simulaciones numéricas que describen el comportamiento dinámico utilizando el software comercial llamado CARSIM. La investigación [9] estableció el modelo dinámico espacial del vehículo para determinar la fuerza vertical Fz, para detectar el límite inminente de las volcaduras.…”
