Course Objectives &
Competences to be
Acquired
The main objective of this course is to impart knowledge in
the construction of vehicle, aerodynamic concept, panelling of
passenger car body trim. At the end of the course the
student will be well versed in the design and construction of
the body of the vehicles.
Course Description: Body construction, Preliminary Design, Aerodynamics
considerations, Body Loads and stress analysis, Strength of
Body Elements.
Course Outline &
Chapters:
1.Vehicle Body construction
Vehicle body, bus body and commercial vehicle body types, conventional
and integral Body Construction, vehicle body construction regulations for
bus body Layout dimensions commercial vehicle construction: Dropsied
body Tipper tanker Van body design.
2.Preliminary Design
Preliminary design considerations floor height side slope space utilization
visibility- visibility tests Methods to improve visibility- visibility
regulations Rear view mirror design safety: safety equipment for car crash
worthiness Drives seat design – Body materials Sheet steel –Light alloys
plastics Glass wood GRP and its properties.
3.Commercial Vehicle Details and Aerodynamics
Classification of commercial vehicle bodies. Construction of Tanker body
and Tipper body. Dimensions of driver‟s seat in relation to controls.
Driver‟s cab design. Compactness of Driver‟s cab. Segmental construction
of driver‟s cab. Effects of rounding sharp front body edges. Effects of
different cab to trailer body Fore body pressure distribution. Effects of a
cab to trailer body roof height. Commercial vehicle drag reducing devices.
Modern painting process of a passenger car body.
4.Vehicle Body Loads and stress analysis
Idealized structure- Structural surface shear panel method symmetric and
asymmetrical vertical loads in car longitudinal loads- different loading
situations- Load distribution on vehicle structure- Types of load carrying
structure closed integral structure. Opens integral structure. Flat or punt
type structure- car body structure Different types- Load distribution in a car
structure load in torsion and bending and torsion- Stress analysis of integral
bus body introduction to Finite element methods.
5.Strength of Body Elements
Utilization of the material Rigidity thin shell assumption Torsion forces in
end load carrying members and panels spoot welded joints Forces on a
weld body testing. Body trim .Body mechanisms –painting selection of
paint process.
