Bugatti Veyron

My 2nd automobile model in CATIA. Took 2 days to model (16 hours straight streak).

The Bugatti Veyron EB 16.4 is a mid-engined grand touring car, designed and developed by the Volkswagen Group and manufactured in Molsheim, France by Bugatti Automobiles S.A.S.

The Super Sport version of the Veyron is the fastest street-legal production car in the world, with a top speed of 431.072 km/h (267.856 mph). The original version has a top speed of 408.47 km/h (253.81 mph). It was named Car of the Decade (2000–2009) by the BBC television programme Top Gear. The standard Veyron won Top Gear's Best Car Driven All Year award in 2005.

BMW i8 Vision Efficient Dynamics

BMW i8 Concept model in CATIA by me. Took me straight four days about 60 hours to model this.
The Vision Efficient Dynamics concept car is a plug-in hybrid with a three cylinder turbodiesel engine. Additionally, there are two electric motors with 139 horsepower. It allows an acceleration to 100 km/h (62 mph) in 4.8 seconds and an electronically limited top speed of 250 km/h (160 mph).
According to BMW, the average fuel consumption in the EU test cycle (KV01) is 3.76 litres/100 kilometers, (75.1 mpg imp), and has a carbon dioxide emission rating of 99 grams per kilometer (1,3 l/100 km and 33g CO2/km ; EU-PHEV ECE-R101). The estimated all-electric range is 50 km (31 mi), and the 24-litre diesel tank extends the total vehicle range to up to 700 km (430 mi). The lightweight chassis is made mainly from aluminium. The windshield, top, doors and fenders are made from polycarbonate glass, with the body having a drag coefficient of 0.22.

Turbine Rotor

A turbine is a rotary mechanical device that extracts energy from a fluid flow and converts it into useful work. A turbine is a turbomachine with at least one moving part called a rotor assembly, which is a shaft or drum with blades attached. Moving fluid acts on the blades so that they move and impart rotational energy to the rotor. Early turbine examples are windmills and water wheels. Rotor is the rotating part, and the stator is the stationary part of the machine.

Torsen Differential

The Torsen differential works just like a conventional differential but can lock up if a torque imbalance occurs, the maximum ratio of torque imbalance being defined by the Torque Bias Ratio (TBR). When a Torsen has a 3:1 TBR, that means that one side of the differential can handle up to 75% while the other side would have to only handle 25% of applied torque. During acceleration under asymmetric traction conditions, so long as the higher traction side can handle the higher percentage of applied torque, no relative wheelspin will occur. When the traction difference exceeds the TBR, the slower output side of the differential receives the tractive torque of the faster wheel multiplied by the TBR; any extra torque remaining from applied torque contributes to the angular acceleration of the faster output side of the differential.

Torsen differentials are used in many of the various Audi Quattro models, excluding the A3 & S3 and TT (which have transverse-mounted engines and use Haldex Traction 4WD systems).

 

 

 

 

 

 

 

 

 

Epicyclic differential 3D Model/Simulation

An epicyclic differential uses epicyclic gearing to split and apportion torque asymmetrically between the front and rear axles. An epicyclic differential is at the heart of the Toyota Prius automotive drive train, where it interconnects the engine, motor-generators, and the drive wheels (which have a second differential for splitting torque as usual). It has the advantage of being relatively compact along the length of its axis (that is, the sun gear shaft).

Epicyclic gears are also called planetary gears because the axes of the planet gears revolve around the common axis of the sun and ring gears that they mesh with and roll between. In the image, the yellow shaft carries the sun gear which is almost hidden. The blue gears are called planet gears and the pink gear is the ring gear or annulus.

Centrifugal Turbine Impeller 2D Drawings/3D Model/Video Tutorial

This model is actually was part of work of my friend. He was having problem reading the drawing file so he asked me if I could help me making this part. At start I was thinking where to start but it was fun modeling this little part as help for my friend. This is actually part of Steam turbine assembly. This part is totally accurate.

Single Plate Clutch 2D Drawings

Axial Vector Engine

A swashplate is rigidly fixed to the CAMDisk, and goes round with it as a unit. Therefore the connecting rods are not fixed to the plate in any way, but push on it with rollers or slipper pads that can glide over the surface of the plate as it turns. The main point of attraction is the use of CAM-Disk in place of Crank shaft to provide reciprocation. Since the Engine is double Reciprocatory with corresponding strokes at both sides, there is no unbalancing of masses i.e. full balanced. Battery Ignition System is used with a spark plug for each cylinder. There are one inlet and one exhaust for each cylinder. Fins thickness is not calculated but 5mm is more than enough. Fuel Type used is Gasoline and the engine can found application in Aerospace as well as Automotive. Engine is mainly a torque converter type rather than speeder.
Specs:-

Cylinders =12 (6 both sides)
Bore Dia = 80mm
Stroke length = 110mm
Engine Type = Axial Vector Type 4 Stroke
Crank Mechanism = CAM Disk Mechanism
Engine Capacity = 26500cc/1618ci

This model is also winner for CADD Centre Training Services Facebook project contest with more than 1000 votes and stood first in more than 590 entries. Also this is my favorite model.

Connecting Rod of Gasoline Engine

Connecting Rod is the connection between the piston and crankshaft. It joins the wrist pin of the piston with the throw or crankpin of the crankshaft. For a given size engine, lighter the connecting rod and piston the greater the resulting power, and lesser the vibration as a result of the decreased reciprocating weight. The connecting rod is split to permit its being clamped round the crankshaft.

This model was part of my Advanced CAD/CAM lab assignment. Had fun modeling it. There is a funny incident related to it. I was unable to read the distance between the lower split of the connecting rod circular part with the upper circular part. Whole night I tried to understand and finally slept without getting the problem solved. That night I solved this problem in my dream and when I woke up I had the solution. So rather than preparing for college I took 24 minutes to model this drawing.

Had very fun modeling it.
