Body in white (BIW) is the stage in automobile manufacturing in which a car bodys frame has been joined together, that is before painting and before the motor, chassis sub-assemblies, or trim (glass, door locks/handles, seats, upholstery, electronics, etc.) have been integrated into the structure.
What are BIW parts?
Body-in-white (BiW) is the name given to a car bodys sheet when all its components—barring moving parts (e.g., hoods, fenders, etc.), trims (e.g., glass, seats, etc.), or chassis subassemblies—have been welded together.
Which of the following is the part of body side structure of the BIW?
Wing panel - Wing panel are the outer most side panel in the front. Cowl - Cowl is the portion of the body bounded by the front fenders, the base of the windshield, and the rear edge of the hood.
What is meant by term BIW in Catia?
BIW can be defined as the skeleton of a vehicle. The BIW is the structural sheet metal that supports the outer panels of the vehicle and the overall shell of the vehicle. The body of an automobile is organized dependent on the number of designed systems such as doors, seat arrangements, and roof structure.
What is the benefits of monocoque chassis construction?
A monocoque construction will always have better handling and performance compared to a body on frame construction. The floor pan can be placed much lower on a monocoque construction, giving the vehicle a lower centre of gravity. This allows the vehicle to be agiler in terms of handling.
What is the full form of Catia?
CATIA stands for Computer Aided Three-Dimensional Interactive Application. Its much more than a CAD (Computer Aided Design) software package. Its a full software suite which incorporates CAD, CAE (Computer-Aided Engineering) and CAM (Computer-Aided Manufacture).
What is NVH in car?
Car Noise, Vibration and Harshness. NVH is a term used to describe car noise, vibration and harshness that result in varying degrees of dissatisfaction.
Why rough locators are used in BIW fixture?
Rough locators are elements that aid the operator to guide the car panels while loading onto the fixture and ensure a fool-proof assembly.
How many types of chassis are there?
All vehicles come in two types of chassis namely; conventional chassis which is known as frame-full chassis and non-conventional chassis.
What is the difference between chassis and frame?
A chassis is the skeletal framework of a vehicle on which most of the mechanical parts like tires, axle assemblies, steering, brakes, and the engine are fastened. A vehicle frame, on the other hand, is the main structure of the chassis. All the other components, including the chassis, are fastened to the frame.
How is NVH calculated?
Typical instrumentation used to measure NVH include microphones, accelerometers and force gauges, or load cells. Component and subassembly NVH tests are most commonly performed using a vibration shaker while entire vehicles usually on the test track or road simulator testbeds.
How can I raise my NVH levels in my car?
In simple words, vehicle dampening is a procedure in which sound deadening or sound-absorbing materials are used to reduce NVH levels inside a vehicles cabin. These materials are placed over places prone to vibration such as door panels, pillars, roof and floor of the vehicle.
