•
Positions of the
P
2,
P
3, and
P
6 are free to be changed.
•
The idea is to
fi
x the X-coordinates of these points and
adjust their Y-coordinates to achieve a better GA value.
•
Allowable adjustment ranges are 10 mm for
P
2, 20 mm
for
P
3, and 5 mm for
P
6.
•
The maximum stress should not exceed 15 MPa.

[2] The initial value of the width of the
bridge is 30 mm and its allowable range is
20-30 mm.
[3] The initial value of the
radius of the
fi
llet is 10 mm
and its allowable range is
5-15 mm.
[1] we want to
change the values
of
W
and
R
to
reduce the amount
of material.
