Alternative approaches to rear end drag reduction

Introduction

Aerodynamic drag of a commercial vehicle is a large part of the vehicles fuel consumption,
according to Hucho it can contribute to as much as 60 % of the vehicles fuel consumption.
So far aerodynamic design of commercial vehicles has concentrated on the front end of the
vehicle. Since it produces most drag it has been the most urgent part to optimise. This
optimisation can easily be spotted on trucks and tourist coaches. The rear end confi ....etc

FOUR WHEEL STEERING SYSTEM
ABSTRACT
This paper deals with the details of four wheel steering (4WS) system. With the help of this system all the four wheels can be turned to any direction using the steering. Thus the vehicle can be controlled more effectively especially during cornering and parking. Also the speed of the vehicle can be increased or decreased.
There are three types of production of four-wheel ¬steering systems:
1. Mechanical 4WS
2. Hydraulic 4WS
3. Electro/hydraulic 4WS
The mechanical 4WS uses two separate s ....etc

ABSTRACT
When objects move through air, forces are generated by the relative motion between the air and surfaces of the object. Aerodynamics is the study of these forces, generated by the motion of air, usually aerodynamics are categorized according to the type of flow as subsonic, hypersonic, supersonic etc.
It is essential that aerodynamics be taken in to account during the design of cars as an improved aerodynamics in car would attain higher speeds and more fuel efficiency. For attaining this ae ....etc

FABRICATION OF FOUR WHEEL STEERING SYSTEM
INTRODUCTION
 The front-to-rear wheel alignment plays a significant role in the directional stability of a vehicle.
 Often the lack of stability causes a dangerous drive.
 Up to the mid-1950s the majority of cars suffered from over-steer, mainly due to the uncontrolled movement of the rear axle caused by spring deflection which is initiated by body roll.
 To ....etc

Introduction
Preface To SWARAJ
Punjab, the bread basket of India, the land with 50376 sq. Km is situated in Northern part of India. It is agriculturally Indiaâ„¢s most advanced and most prosperous state. Punjab Tractors limited was promoted by PSIDC as one of its projects in 1970 for the manufacturing of agricultural tractors. Since, this gave independence to country from import of tractors, so brand name SWARAJ, total independence was given.

SWARAJ tractors conceived in 1965 by a team of dedicated engineers a ....etc

ABSTRACT
Automotive vehicles are increasingly being equipped with collision avoidance and warning systems for predicting the potential collision with an external object, such as another vehicle or a pedestrian. Upon detecting a potential collision, such systems typically initiate an action to avoid the collision and/or provide a warning to the vehicle operator.
This system consist of a distance-measuring system based on ultrasonic sound utilizing the PIC 16f877A microcontroller and transmits a burst of ultras ....etc

ABSTRACT

VEHICLE HANDLING, STABILITY,AND BIFURCATION ANALYSIS FOR NONLINEAR VEHICLE MODELS

Vehicle handling, stability, and bifurcation of equilibrium conditions were studied
using a state vector approach. The research provided a framework for an
improved method of vehicle handling assessment that included non-linear regions
of performance and transient behavior. Vehicle models under pure lateral slip,
constant velocity, and constant front steer were developed. Four-wheel, two-axle
vehicle models were evolved from si ....etc

Abstract:
Anti-lock braking systems (ABS) take a lot of the challenge out of this sometimes nerve-wracking event. In fact, on slippery surfaces, even professional drivers can't stop as quickly without ABS as an average driver can with ABS.anti-lock braking system, or ABS is a safety system which prevents the wheels on a motor vehicle from locking up (or ceasing to rotate) while braking.A rotating road wheel allows the driver to maintain steering control under heavy braking by preventing a skid and allowing the wheel to cont ....etc

VEHICLE SKID CONTROL
1. INTRODUCTION
Vehicle skid can be defined as the loss of traction between a vehicleâ„¢s tyres and the road surface due to the forces acting on the vehicle. Most skids are caused by driver error, although only about 15% of accidents are the direct result of a vehicle skidding. Skids occurring in other accidents are usually the result of last minute action, by the driver, when faced with a crisis ahead rather than actually causing an accident. Skids can occur both in the dry and wet as well as ....etc

ABSTRACT


If you are involved in a rear-end car accident, statistics tell us that you
have a one in four chance of sustaining a whiplash injury. Whiplash is caused
when the head is very quickly jerked backward and forward at the moment of
collision, resulting in damage to the muscles and ligaments in t ....etc

F1 Cars

INTRODUCTION
Car racing is one of the most technologically advanced sports in the world today. Race Cars are the most sophisticated vehicles that we see in common use. It features exotic, high-speed, open-wheel cars racing all around the world. The racing teams have to create cars that are flexible enough to run under all conditions. This level of diversity makes a season of F1 car racing incredibly exciting. The teams have to completely revise the aero ....etc

This report presents the results of an independent evaluation of the Automotive Collision Avoidance System (ACAS). The ACAS integrates forward collision warning (FCW) and adaptive cruise control (ACC) functions for light-vehicle applications. The FCW detects, assesses, and alerts the driver of a potential hazard in the forward region of the vehicle. The ACC provides automatic brake and throttle actuation in order to maintain speed and longitudinal headway control. Through the integration of these two functions, ACAS is intended to improve auto ....etc
