Modeling and Simulation of Motorcycle Ride Comfort Based on Bump Road

Abstract: Through analyzing the motion when motorcycle runs on the bump road, the 5-DOF multi-body dynamics model of motorcycle is developed, the degrees of freedom include vertical displacement of sprung mass, rotation of sprung mass, vertical displacement of driver, and vertical displacement of front and rear suspension under sprung mass. According to Lagrange Equation, the differential equations of motion and state-space formulation are derived. Then bump road is simulated by triangle bump, and input displacement is … Show more

“…The design of the damping characteristics of the passive (hydraulic type) suspension is always the result of a trade-off between the ability to isolate the vibration and vehicle handling: minimization of suspension travel cannot be accomplished with a simultaneous maximization of the ride comfort. This problem is even more important for motorcycles, since they are much more sensitive than other vehicles, both to the load variations and to the shocks caused by the road asperities [2]- [4]. In this framework, semi-active suspensions have received a lot of attention since they provide the best compromise between cost (energy consumption, actuators, sensors hardware) and performance (safety and comfort requirements) [5].…”

“…Además, otros factores cruciales a considerar son el diseño ergonómico, la elección de materiales y la estabilidad dinámica del vehículo, los cuales desempeñan roles fundamentales. Una forma de estudiar el confort consiste en realizar ensayos asistidos por computadora ( 22)- (24). No obstante, esta alternativa asume que el vehículo se comporta idealmente, lo cual frecuentemente se aleja de la realidad pues no incluye los efectos de las carreteras, la falta de mantenimiento y las modificaciones físicas sobre el automóvil.…”

“…The literature presents two primary approaches for assessing comfort in motorcycles: virtual and experimental testing. Virtual testing involves the use of computer-aided simulations to analyze the impact of vibrations on driver's comfort [19][20][21][22]. However, this approach assumes an ideal vehicle performance, which is often not the case due to road conditions, maintenance issues, and physical modifications of the vehicle.…”
