Self Powered Vehicle Project

During my studies in diploma level, i has been assigned to designs a self powered vehicle that didn't required fuel or cells, the vehicle model must moved by using only mechanical mechanism. I and my group member had designed a model of BMW X6 and we use the mechanism of retraction, which in case cause the pulling and thus give the force to the tires to move,, 

FABRICATION PROCESS OF BMW X6 MODELS

PROVIDING MATERIAL AND TOOLS FOR BUILDING THE MODELS

To build our BMW X6 car, we first provide some materials and tools in order to build it. Majority of material s we used came from recycle material. We used some old box, bottles, soda can, old tyre tubes, old newspaper, and other things. For the tool to built our model, we used scissors, glue, staples, rulers, knife, and also screwdrivers.

 BUILDING THE CHASSIS OF THE MODELS.

In order to get better model for bmw x6, we had used our knowledge in chassis studies to built a better chassis for the models. Our frames was a ladder frame. This types of frames consist of side members and cross members. It was strong and can  support heavy loads. The materials we used was a wire casing as this types of materials was lighter, good in bending and also strong. This frames was built carefully and the dimensions was make sure to be accurate. Then, we riveted the cross members on to the side members. The cross members provides us mounting for the moving mechanisms and also the body of the model.

BUILDING THE BODY OF THE MODELS.

To built the body of the models, we uses old boxes as main materials for it. We used this types of materials because the flexibility of the box and also their contribution of weight for our bmw x6 models was less compared to other materials. Firstly, the box had been sketch all the dimension as needed by us. Then after the sketching had finished, we cut the box according to the sketch that we made. All the box  then had been joined together by cellophone tapes and also staples. All the bends and the critical place had been estimated precisely in order to get better results for our models.

 

APPLYING THE COLOUR TO THE MODELS.

After the body of the models had been finished, then come the moments for us to apply some colour to it. We used the spray paint due to ease of handling and cheap in price. All parts of the body had been sprayed with a maroon colour as it was the colour decided by both of us. After spraying the paint, it was allowed to dry in some minutes in order to make sure the paint does not wipe out.

 

 WHEEL CONSTRUCTING.

For our models to move smoothly in a tracks, the wheels had been constructed and attached to the frames. The materials for wheels that we used are soda can, papers, and also old tyre tubes that act as a surface of the wheels which will provide better grip for tractions. The tyres are held by steel rods that we get from the old steel hanger. The wheels was make sure to be balance in order for the car to move smoothly.

 

MECHANISMS FOR MOVINGS OF THE MODELS.

For moving, we used tape measure as the heart of the car. The reason for us to use this things  was absolutely because the tape measure could give a smooth and even movement of the car.

BMW X6 was a mid-size luxury vehicle produced by German automaker BMW. It was five door car and front engine all wheel drive vehicles. This type of model was so stylish and exclusive. On our project, we had been assign to built amodel of BMW X6 by recycled material and the mechanisms that can make the vehicle move also had been gave for us to think about. During the construction of our models, there are many challenging part that we had already face d in order to get a better model of this types of car. Management of cost, time and also materials was  been planned by us carefully to construct a better model. By looking at the cost that we had invest in order to complete this task, we firstly listed all the types of materials that we wanted to use for construction. As this task required us to used recycled materials or things, some of the cost had been reduced as the recycled material are easy to find and no charge for taking this materials. Although the budget had been reduced by the using of recycled parts, still there are some money to be spend on tools. So the proper list of things-to-get was made again in order to make sure all the budget flows in a correct way. The constructing of this models begin earlier before where we are assigned to built BMW X6 on SolidWorks Programming software. By using this softwares, an actual looks of BMW X6 was built in that programs and it was a better idea to make us more familiar to the models that we had to built. After the construction of the models in the programs, we then proceed our steps to built an actual looks or models of BMW X6. By using materials such as old box, bottles, soda can,wire casings, old tyre tubes and also newspaper, a model of BMW X6 was constructed. Many discussions that we had undergo in order to get better results and to avoid any errors that may come when least expectations was taken. The body of the models was built by old boxes. The use of this materials was very flexible and cost savings. Sketching of the car parts on the boxes was then been cut correctly. After all parts finished cutting, then we attached all the corresponding parts altogether with cellophane tapes and also staples. Using of staples makes the body of the model became more rigid eventhough not too strong. Then it comes for the frames of the models. The uses of wire case was very light and reduce the weight of the models if the models uses plywood or other things, this is because wire case was made up of plastics. On the upperside of the frames, there situated our moving mechanisms. We used tape measure as this things could move a car by springs pullback. The uses of this types of mechanisms also was very efficient as we can expects the length of travels of our cars. The strings was clamp at the axle of the wheel and before starts was make it or pull it under tensions. When the strings was released, the springs inside the tape measure will pull back the strings in its original situation, not in tension.
