The document discusses the use of finite element analysis (FEA) for evaluating the design of a robotic gripper assembly before the official approval process. It outlines the need to assess the deflection uniformity and stresses of a complex assembly consisting of over 50 parts, emphasizing the importance of accurate calculations and rapid assessments. The simulation can be completed quickly, allowing for design changes and providing a user-friendly setup with support.

2. CASE 1 – ROBOTIC GRIPPER – FEA
Plant Management
Fixed to the load block or boom here
200N gripping force
Objective: before starting official approval process, the designer
wants to assess the uniformity of the deflection during grappling.
● New design for gripper assembly
● 50+ part assembly, Roark hand calcs overly simplified
● 6 times safe working load for lifting equipment
● Proof load testing a complete entire assembly is expensive to get
wrong
How can I assess the assembly
stresses quickly and accurately?
Are my calculations correct?
