Here is an example of static hand analysis. Our customer needed to certifiate its gripper. This gripper was supposed to carry a payload up to 80kg. French Regulation dealing with hanged payload tooling (NF-EN-13155 Appareils de levage à charge suspendue) imposes a x2 safety factor on payload, thus payload assumed was 160Kg (1600N).
He sent us its CAD geometry, for us to check it.
A simple static analysis has been performed and leaded to a geometry change request to pass the pliers axis.
