SUMMARY:A Harmonic Balance Approach for Designing Compliant Mechanical Sys
tems with Nonlinear Periodic Motions
DESCRIPTION:Technical Papers, Technical Papers Q&A\n\nA Harmonic Balance A
pproach for Designing Compliant Mechanical Systems with Nonlinear Periodic
Motions\n\nTang, Zehnder, Coros, Thomaszewski\n\nWe present a computation
al method for designing compliant mechanical systems that exhibit large-am
plitude oscillations. The technical core of our approach is an optimizatio
n-driven design tool that combines sensitivity analysis for optimization w
ith the Harmonic Balance Method for simulation. By establishing dynamic fo
rce equilibrium in the frequency domain, our formulation avoids the major
limitations of existing alternatives: it handles nonlinear forces, side-st
eps any transient process, and automatically produces periodic solutions.
We introduce design objectives for amplitude optimization and trajectory m
atching that enable intuitive high-level authoring of large-amplitude moti
ons. Our method can be applied to many types of mechanical systems, which
we demonstrate through a set of examples involving compliant mechanisms, f
lexible rod networks, elastic thin shell models, and multi-material solids
. We further validate our approach by manufacturing and evaluating several
physical prototypes.\n\nRegistration Category: Ultimate Supporter, Ultima
