Introduction A door is a hinged part which is used for entry and exit of passengers and commodities from the vehicle.  Back door is located behind the passenger seat which provides access to luggage compartment. In almost all the cars back doors are operated with the help of gas stay which in turn reduces the effort…

Introduction An automobile roof or car top is the portion of an automobile that sits above the passenger compartment, protecting the vehicle occupants from sun, wind, rain, and other external elements. Roof is connected to A-Pillar, B-Pillar, C-Pillar to cover the front and rear door. Roof is generally supported by a set…

Introduction Hoods are those part of the automobiles that take huge loads during frontal crashes. So it is primary concern of the design engineer to design a hood with greater strength. Since hoods need to withstand greater bending loads during frontal crash, it is important to design hoods with greater section modulus.…

Introduction A fender is the curved portion of the car’s body that sits over and houses the wheels. The purpose of a fender is pretty simple. Its purpose is to keep mud, rocks, and other road debris from being thrown around by the tires. In other words, the fender is a housing for the wheels that keeps road…

Introduction The hood or bonnet is the hinged cover over the engine of motor vehicles. Hoods can open to allow access to the engine compartment for maintenance and repair. Hoods are typically made out of the same material as the rest of the body work. This may include steel, aluminum, fiberglass or carbon fiber. However,…

Introduction Underbody coating is usually a dense cladding (often based on rubber) applied uniformly to the undercarriage of the automobile. It is normally sprayed or painted. The main purpose of undercoating is to check rust especially in the body components like frame rails along with other exposed metal parts. Underbody…

What is benchmarking? Benchmarking is defined as the process of measuring products, services, and processes against those of organizations known to be leaders in one or more aspects of their operations. Benchmarking provides necessary insights to help us understand how an organization compares with similar organizations,…
