The purpose of this document is to describe important tire characteristics and their effect on vehicle performance. Characteristics considered are those that the Formula SAE judges have deemed important for discussion on tires at competition and include coefficient of friction, slip angle, slip ratio, camber angle, cornering stiffness, camber stiffness, self-aligning torque, normal load sensiti...

Abstract With the increasingly fierce competition in automotive industry, requirements for automobile wheel hub assembly line weregetting higher and higher, matching machine has become an indispensable part of line. In this paper, structure pneumatic drive servo was adopted by tire machine, which ensured production rhythm accuracy requirements. According to overall index automatic machine,the s...

Compared with pneumatic tires, non-pneumatic tires have incomparable performance, in terms of load bearing and safety. In this paper, the static characteristics pure longitudinal slip tire are studied by combining experiments simulations. The test results show that radial stiffness original structure is nonlinear, sliding seriously inconsistent, brakes very sensitive, driving slightly soft. A s...

This article studies the influence of speed a car with low and ultra-low profile tires, 14ʹʹ 16ʹʹ, negotiating turn through an interactive software system developed by us in MATLAB environment. The changes normal lateral loads wheels are obtained characteristics side slip angle (known as slip) pneumatic tires determined. Taking into account wheels, determines center turn. for both types given. ...

In this paper, we are interested in developing a robust tire-force estimator for heavy duty vehicles. We use a combined model of the articulated vehicle: a yaw plane model for the chassis motion and a vertical plane model for the axles. In the proposed method, we make use of the on-board available sensors to which are added lowcost sensors. In order to optimize the sensors configuration, a robu...

The viscoelastic effect of rubber material on creation of rolling resistance is responsible for 10-33% dissipation of supplied power at the tire/road interaction surface. So, evaluating this kind of loss is very essential in any analysis concerned with energy saving. The transient dynamic analysis for including the rolling effects of the tire requires long CPU time and the obtained results are ...

Fused Deposition Modeling (FDM) is widely used as a method in making rapid prototyping and one that developed bicycle. Balance bike type of bicycle does not use pedal. moves by being pushed with legs while running or walking. One the most important parts tire. However, reality pneumatic tires have disadvantages environmental problems. In this study, tire will be processed 3D printing using Ther...

This paper examines recent horror films in the US in relationship to the economic collapse of 2008 and the Great Recession. Using Rubber (2010) and Iron Invader (2011), it explores how the “killer commodity” resonates with working-class anxieties of dispossession and disposability, especially in the auto industries of the places where the films are set and produced: the US and France. The films...

In view of the problems that fuselage inclines and driving straightness is difficult to guarantee due sinking sliding wheels when high-clearance plant protection machine working in paddy field, this paper takes as research object, based on field environment, establishes a prediction model wheel subsidence through derivation, explores influence different parameters characteristics experiments, s...
