Numerical and Experimental Considerations of Non-linearities for a Trifilar Pendulum

Abstract

Moments of inertia of machine-components or whole machines are essential for numerical simulations, especially for Mutli-Body-Simulations. Various measuring techniques exists, which can be rougly divided in techniques using oscillations or accelerations. One possibility to measure indirectly the inertia properties are multifilar pendulums, for example the trifilar pendulum using a platform and three ropes or filars. A lot of literature dealing with the trifilar pendulums exists. We will give a brief overview of the literature with emphasis to non-linearities. Furthermore, we will investigate nonlinear effects and compare them with experimental and numerical results.
