Abstract
The principal objective of this thesis 1S to develop a geometric method for designingabar-linkage mechanism
to generate a given function of two independent variables.
The problem is approached by using toPological trans-
formation of each of the dependent and independent varia-
bles such that the given functional relation can be expr-
c.ssed in terms of three functions; each of only one vari¬able. For the generation of these functions three
Stephenson six-bar mechanisms of type-I are designed by ~5Lftj the ”overlay” method. The outputs of these function gen-erator mechanisms are fed to an 9dder, the output ofthe adder is then fed to an inverse function generator
mechanism to obtain the given function.
A main part of this Work is devoted to develop a linkage adder? whose performance proved to be very satis¬factory, and it is believed to be the first adder of this type.
The adder and the function generator mechanisms are designed using geometrical methods. The design is, then,improved by using the selective precision synthesis technique.
