This paper studies the application of in-wheel suspensions and airless tires to bicycles. The analyzes suspension solution in two interwoven directions: a model-based study an experimental analysis. On one hand, multi-body simulator allows for detailed dynamic design sensitivities analyses. other proposed architecture is experimentally compared classical bicycle with pneumatic tires. analysis, ...

Non-pneumatic tires (NPTs) have been widely used for their advantages of no run-flat, need air maintenance, and unique stiffness characteristics. This study focuses on the design a spoke Fibonacci spiral non-pneumatic tire (FS-NPT) based its properties three-dimensional stiffness. Finite element (FE) models, parametric studies, designs experiments (DOEs), sensitivity analyses are conducted to e...

A new type of non-pneumatic tire with a flexible spoke structure is proposed to solve traditional pneumatic defects, such as easy bursting, the requirement real-time maintenance keep pressure, and complex manufacturing process. The thermal mechanical coupling characteristics are studied in detail obtain steady-state temperature field distribution pattern under different operating conditions. un...

Wheel numeric and different versions of mobility numbers are important models for predicting the rolling resistance. In this study, data related to the rolling resistance of cross ply and radial ply tires were compared with the resultant values from several models. Also, the preciseness of models in rolling resistance prediction was evaluated. For this purpose F test and 1-1 line method (p≥ 0.0...

Extended Abstract—This paper presents the realization of a prototype of a conversational workflow for a Chatbot in tires domain. The initial purpose has focused on the design of the specific model to manage communication and propose the most suitable tires for users. For this aim, it has been used the Petri Net. Finally, after the implementation of the designed model, experimental campaign was ...

Piezoelectric materials can convert mechanical energy into electrical energy. These have the potential to provide reliable and cost-effective replacements of sources. It ultimately reduce fuel costs in vehicles. The use piezoelectric pneumatic tires enables capturing waste cars because deformations tires. An experimental setup was designed constructed simulate movement pressure inside tire a ca...

When executing turning maneuvers, manual wheelchair users must overcome the rotational inertia of the wheelchair system. Differences in wheelchair rotational inertia can result in increases in torque required to maneuver, resulting in greater propulsion effort and stress on the shoulder joints. The inertias of various configurations of an ultralightweight wheelchair were measured using a rotati...

A numerical procedure has been applied for investigating the temperature distribution in a smooth tread bias tire of a light truck, operated under different speeds, pneumatic pressures, and loading conditions. Prior to simulation by the finite element analysis, two separate sets of testing, namely dynamic mechanical testing and material testing, have been conducted in relation to the evaluation...

Recently, research regarding non-pneumatic tires that are resistant to punctures has been actively conducted, and the spoke structure design of found be a crucial factor. This study aimed analyze vertical stiffness characteristics tire based on shape under application load. The three-dimensional model commercial was obtained from manufacturer (Kumho Tire Co., Inc., Gwangju, Korea), three models...
