Control the output force and displacement for the gripper using Topology Optimization

Hi All,

I am attempting to design a gripper that is flexible enough to conform to the shape of the object and stiff enough to transmit the required grasping forces (in 2D & 3D problems). However, I am wondering if HyperWorks software can design a compliant gripper based on Topology optimization like the example below.

Example:
- Input: 10mm displacement or other value (displacement driven) => The output ports will have specific or maximum values such as 20mm and 20 N (Displacement & forces)
Or
- Input: 20N or other value (force-driven) => The output ports will have specific or maximum values such as 20mm and 20 N (Displacement & forces).

Moreover,  I don't know how to set the contact force or pressure between the gripper and the object.

Thank you,
Hung

    i've seen something similar implemented some time ago, achieved by the usage of DRESP2 equations to compute the advanced responses needed for these applications. these compliant mechanisms have specific objective functions that are not out-of-the-box, thhus some DRESP2 using equations are needed.

    Thank you for your suggestion, I will try it.
