SSS representation of an automotive body structure is as shown below. For SSS analysis, power train load can be assumed to be carried by the cross member between the two fenders. Load of luggage in the trunk is similarly supported by a cross member between the two quarter panels. Both the engine and luggage rest on the cross-member symmetrically about the centreline of the car. Passenger loads are carried by the cross-members in the passenger compartments. Centre of gravity of all the loads are located at different heights from the ground. For the condition when car is carrying two passengers in the front and two in the back, Tabulate the loads that will be considered in part 2 – 4. Assign appropriate symbols for forces to identify them by their source and direction. Draw free-body diagrams of the SSS model when the car is Parked (isometric and side view) Taking a left turn (Top and isometric view) Accelerating (isometric and side view)
