Abstract:
This paper presents a unique solution to the problem of planar compliant mechanism design by means of geometric morphing technology and isogeometric analysis (IGA). A new transformable triangular mesh (TTM) component is developed based on geometric morphing technology, which can generate the required topology with different feature sets from a surface that has zero boundary component (interior hole) under the control of Laplace energy and mesh operations. Such flexible TTM component is helpful in overcoming the initial dependency of conventional topology optimization methods in which the layout of parameterized components often affects final optimized results.
