The formula cars need high tire grip on racing challenge by reducing rolling displacement at corner or double change lands. In this case study, the paper clarifies some issues related to suspension system with inerter to reduce displacement and rolling angle under impact from road disturbance on Formula SAE Car. We propose some new designs, which have an advance for suspension system by improvi...

Abstract. Simulating numerically the sound radiation of a rolling tire requires the solution of a very large and sparse gyroscopic eigenvalue problem. Taking advantage of the automated multi– level substructuring (AMLS) method it can be projected to a much smaller gyroscopic problem, the solution of which however is still quite costly since the eigenmodes are non–real and complex arithmetic is ...

Problem. Rolling resistance is one of the most important operational characteristics a car tire. First all, fuel consumption, durability and service life tire depend on rolling resistance. Of course, higher resistance, faster more intensively will wear out. Also, braking parameters, such as deceleration and, accordingly, distance, may indirectly characteristics. In turn, influenced by propertie...

Rolling resistance is the of a wheel that will roll or rotate due to friction between outer surface and track surface. This study aims determine effect tread patterns on coefficient rolling resistance. The tires be used in this are hard compounds with ratio pattern raised by 2 mm tire hardness 79.5 Ha, using pressure variations at 30 Psi, 40 50 Psi. Coefficient value 1.39% 8.05 N. These results...

Euler-Lagrange coupling method is used to establish the fluid-structure interaction model for tires with different tread patterns by obtaining grounding mark and normal contact force between tire road surface during rolling. The altering of load force, pressure, water film thickness in relation effect on tire-road both constant speed critical hydroplaning was analyzed. Results show that are pos...

Reduction of tire-road noise is an important issue when developing luxury cars and electric vehicles. In this context, the air-cavity mode source spindle forces transmitted to suspension that then increase interior levels. When a tire rotates, cavity near 200 Hz splits into two adjacent modes due Doppler effect deformation. That split can lead increased levels both longitudinal vertical at sinc...

The damage that occurs around the tire bead region is one of critical failure forms a tire. Generally, prediction durability carried out by experimental method. However, it takes lot money and time to conduct experiments. Therefore, determine fatigue life radial bead, reasonable method proposed in this paper. Fatigue testing rubber compounds ΔSED-number cycle (Nf) was applied. maximum strain en...
