Abstract— As we are using bike instead of car for our daily work, because it is cheapest as compare to car but it also has some limitation such as, it is difficult to travel long distance and travel in rainy season because bike is not giving that much comfort which a car can give. To remove these limitations we need something which can give the comfort of car as well as mileage of bike. That’s why it’s time to move towards a ‘BICAR’. Bicar is a combination of bike and car. It will go to give the comfort of car with high mileage of bike. Bicar is a small car which needs less space to park, having a low weight and it is very useful in all kind of weathers such as rainy, summer and winter. As handicapped peoples are unable to drive bike as well as car this is a type of bike which is completely balanced like car, thus it can also be useful for handicapped person. Keywords- Structural analysis, ANSYS, Geared Motor, Chassis.

I. INTRODUCTION

After invention of Bike, Car and Heavy vehicles, the transportation become very easy. Before this invention it is difficult to travel from one place to another place and also require huge time. Thus the vehicle mentioned above reduces the efforts up to large extent. But use of vehicle is not economical because of increasing fuel prices.

II. PROBLEM DEFINITION

Now a day’s people prefer bike than car because it is having good mileage which is economical as well as it has low price as compare to car. But this economical vehicle has some limitations such as, it is difficult to travel long distance, it not provides any protection to the rider in rainy, winter and summer season. If the person travels the long distance on bike, he has to suffer the back pain. That’s why it’s needed to make the product which can fulfill the features of bike and car. Such that it will give comfort of car & the mileage of bike.

III. METHODOLOGY

A. Chassis The chassis can be called as skeleton of a vehicle besides its purpose being seating the driver, providing safety and incorporating other sub systems of the vehicle. After study, I decided to use tubular space frame chassis which is used for the urban car. Since ladder chassis is not strong enough, motor racing engineers have developed a 3-dimensional design which known as tubular space frame. Tubular space frame chassis employs dozens of circular-section tubes (some may use square section tubes for easier connection to the body panels though circular section provides the maximum strength), position in different directions to provide mechanical strength against forces from anywhere. These tubes are welded together and form a complex structure. For

higher strength required by high performance sports cars, tubular space frame chassis usually incorporate a strong structure under both doors. Tubular space frame chassis also very strong in any direction compared with ladder chassis and monocoque chassis of the same weight.

B. Cad Model

I design the primary model of chassi in ‘CATIA’ in which engine is located at back side of driver’s seat and balancing mechanism is between seat and engine. Following figure shows the overview of chassi.

Figure 1: primary CATIA design

C. Selection of Material for Chassi

Shear stress in the cross section of a shaft is zero at the Centre and increases linearly to the maximum value at the outer surface. In case of solid shaft, stress in the material near the Centre is very less and hence strength of the material near the Centre is not utilized, in case of hollow shaft there is better utilization of strength of the material. Hence, Hollow circular cross section is economical as compared to that of solid circular cross section. To reduce the weight of the vehicle and to improve the vehicle’s power to weight ratio, Material selection plays an important role. Thus after analyzing the number of materials I selected Cold Rolled Carbon Steel (CRC). It offers a range of good mechanical properties like high strength, good toughness, good surface finishing, excellent corrosion resistance to atmospheric conditions, good workability, excellent weld ability and widely available.

D. Welding for Chassi

For Welding the pipes of CRC to build chassi ‘MIG’ welding is selected. Because CRC material is easily get welded by this type of welding and it is cheapest and easily available.

E. Specifications of Bicar The BI-CAR is having following Specifications.

Ground clearance 1 feet (304.8mm). Overall length is 6 feet. Width is 850 mm. Height is 1850 mm from chasse’s lower end. The radii of wheel is 1 feet. Engine type- Four Stroke 150cc (Bajaj Pulser). Mechanism- automatic balancing without gyroscope. Numbers of wheels- 4 Wheels(2 Primary and 4 Secondary) Number Of seat- Two Weight of Bi-Car- Approx 220kg Cooling System- Air Cooling System Expected Mileage Of Bi-Car- 35 - 40km/lit F. Balancing Mechanism

For balancing mechanism geared motor is used with scissor jack. Geared motor can easily operated by DC power source with 12 volts, 9 ampere current. Thus as the speed goes above 30 km/hr, sensors sense the speed and operate the motor to lift the wheels and bicar will run on only two wheels. And as the speed come below the 30 km/hr, sensors again sense the speed and operate the motor to move the wheels in downward direction and then vehicle will run on 6 wheels, thus completely balanced.

IV. EXPECTED OUTCOME

After completion of vehicle it can give the following benefits. Everyone (Men & Women) can drive this bi-car. Handicap person also able to drive this

vehicle with simple modification. In all whether vehicle can be used without any environmental resistance. Economical and affordable vehicle. Feel of Sporty Car which is economical and affordable. The face of a future of transportation. Traffic problem can also be solved. It provides huge safety to human being as compare to bike.
