Stiffness of the beam. Calculating beam deflection requires knowing the stiffness of the beam and the amount of force or load that would influence the bending of the beam. We can define the stiffness of the beam by multiplying the beam's modulus of elasticity, E, by its moment of inertia, I. The modulus of elasticity depends on the beam's material. The joint stiffness for a six-revolute industrial robot was previously estimated by integrating the stiffness of the gear pairs, reducers, and rotational links in the transmission system and subsequently using a stiffness conversion formula related to the transformation ratios. 10 –12 However, the results based on the analysis still produced ...
