2. LEAF or LAMINATED SPRING
•The springs which are made of several plates
(Leaves) of varying lengths that are held together by
means of clamps are called LEAF or LAMINATED
SPRINGS.
•These springs are mainly used are shock absorbers in
automobiles.

3. TYPES OF LEAF SPRINGS:-
LEAF SPRING
SEMI ELLIPTICAL QUARTER ELLIPTICAL

4. ANALYSIS OF SEMI ELLIPTICAL LEAF SPRING
SUBJECTED TO A POINT LOAD W

5. ANALYSIS OF SEMI ELLIPTICAL LEAF SPRING

7. Determination of Number of plates of
Semi Elliptical Leaf Spring
•In practical situations the Maximum Bending Stress
and Deflection of Leaf Spring in limited to a
particular value.
•Thus Number of plates of leaf spring and plate
dimensions (width and thickness) are determined by
putting the limiting values in Bending Stress and
Deflection formulas.
