DESIGN OF SOLAR & ELECTRIC CAR

INTRODUCTION

Today's world is totally depend upon the automobiles without this it is difficult to imagine But as the technology is increasing day by day we are forgetting one should consider the environment.So in order prevent environment from disaster but move ahead in technology we had designed a concept car which is eco friendly and long life

NEED TO CREATE SOLAR & ELECTRIC CAR

1. Eco friendly2. Uses solar Energy 3. Electric cars are much more

reliable and require less maintenance than gas-powered cars. You don't even need to get your oil changed every 3,000 miles!

4. Petrol and diesel can be used for other services like defense, space project, & other important works

CONCEPT

Powered by sun’s energySolar array collect the energy from the sun and

converts it into usable electrical energyPower trackers convert it into the required

voltage Motor controller sends power to the motor

Sun rays

Solar energy converted to electric energy

Electric energy runs the motor

Motor runs the car

CONTENTS

•Design in pro e•Advantages•Specifications & Material used•Driver Controls & Mechanical Systems •Rack & pinion video•BRAKING SYSTEM•CHASIS•Body and safety

Specifications1. Mild steel rods (hollow)

Inner diameter = 27mm outer diameter = 30mm

2 Type of weld – arc weld

Weld rod diameter- 3.5 mm Type of weld material- mild steel Current range- 130-140 ampere

3. Sheet metal type - steel thickness – 3mm

DESIGN• What is PRO E ?• Product research orientation

engineering• It is developed by PTC-• Parametric technology corporation • It is a U.S based software company• In the year of may 1985 by DONALD

K. GRIERSON • Pro e is a software which is used to

design the 2D & 3D Parts modelingWe have use PRO E WILDFIRE 4.0 for making the design of our car.

ADVANTAGES• User friendly• Complex shapes and

parts can also be designed easily

• High accuracy can be obtained while designing

• Comparing with other software like AutoCAD, Autodesk inventor ,etc. pro e is less time consuming while designing

Comparison of pro e with others

ADVANTAGES

• It meet the demands in the field of aerospace, defense, and other heavy equipment's

• It has many customers like Boeing, Ferrari, John Deere, and Lawrence Livermore labs, etc

• One of the biggest advantage is it can handle more than million assembly parts.

DRIVER CONTROLS & MECHANICAL SYSTEMS

• Steering systemWe used rack and pinion

steering mechanisms, where the steering wheel turns the pinion gear; the pinion moves the rack, which is a linear gear that meshes with the pinion, converting circular motion into linear motion leads to turning of wheel

BRAKING SYSTEMIn braking system we have used drum brakes to stop the vehicleas the brakes are applied the brake wire gets tightened and the cam gets rotated due to which the brake shoe internally expand and touches the wheel drum and due to which the vehicle stops and after releasing the brake with the help of spring action the brake shoe again come back to original position

CHASIS•FOR CHASIS WE DID THE DESIGN IN PRO E AND COMING TO MANUFACTURING WE USED MILD STEEL RODS AND WE JOIN THEM WITH ARC WELDING… • A TOTAL OF JOINTS WHICH ARE WELDED ARE 30• A TOTAL OF 48 WELD RODS IS USED TO MAKE THE CHASIS•WE HAVE TRIED TO MAINTAIN THE CENTER OF GRAVITY AS LOW AS POSSIBLE

Body and safety

• The design of this model is drawn in pro e

• The design of the car is very important not only for the look but also in terms of the safety

• In terms of design we gave the look of truck shape

• For extra safety we have design the chassis such that it can during the time of accident the rods bend in such a way that it minimize the risk at the time of accident
