P2(90, 40)


P3(69,120)


P4(35,160)


P5(34,100)

Y
•
Positions of the P2, P3, and P6 are free to be changed.
•
The idea is to fix the X-coordinates of these points and
adjust their Y-coordinates to achieve a better GA value.
•
Allowable adjustment ranges are 10 mm for P2, 20 mm
for P3, and 5 mm for P6.
•
The maximum stress should not exceed 15 MPa.

Triangular Plate
Problem Description

[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 fillet 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.
