Abstract

There is no apparent boundary to identify
the degrees of freedom (DOF) of compliant mechanisms.
One usually needs to compare output displacements,
under the same dimension, to identify the DOF of a
compliant mechanism. This paper proposes a
normalization-based approach to the mobility analysis
of spatial compliant multi-beam modules using a
normalized strategy. Firstly, two spatial non-tilted and
tilted three-beam modules are modeled, and their
corresponding compliance matrices are analyzed to
reflect the DOF of the two modules straightforwardly.
The results are compared with those obtained without
normalization. It is shown that the proposed approach is
better than the traditional ones without normalization.
Then, two double non-tilted and tilted three-beam
modules are proposed and analyzed for potential
applications.
