Abstract Design of any system is imperfect without optimization. The common
problem faced for any design engineer during designing of a tubular race car chassis
is the determination of optimum parameter for the tube. This optimization technique
is specifically applied to the chassis of FSAE car. This technique provides the most
optimum equation which relates all the controllable factors of the chassis. The
optimum equation is found using point-set topology, surface fitting methods, iter-
ations in analysis softwares. Controllable factors like diameter, wall thickness,
deflection, yield strength are made a 3D surface function in the form of z =(ax
n
)
(y
m
)+(bx
n-1
)(y
m
)+(cx
n
)(y
m-1
)+ … px + cy. The obtained equation is the most
optimum equation which relates all the controllable factors for a specific loading
condition. Considering loading condition as side impact condition, if the optimum
parameter has to be chosen (say diameter), the priority of deflection and the yield
strength of the material is input into the equation, which contains the deflection and
yield strength as other parameters. The equation is solved to obtain the most
optimum diameter for the specified inputs. If all the inputs are given to the equation
and if the equation is satisfied, the given inputs are said to be optimum inputs (Zero
deviation from the given equation). Any variation either below or above the
equation are considered to be positive or negative deviation measured from a
reference of the optimum equation.
