Flexible Gripper

Problem Description

P1( 70, 0) P2( 90, 40)

P3( 69,120)

P4( 35,160)

P5( 34,100) P6( 24,60) P7(0,50)

X

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

W

R

[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.
