Constrained motion design with distinct actuators and motion stabilization

The design of adaptive structures is one method to improve sustainability buildings. Adaptive are able adapt different loading and environmental conditions or changing requirements by either small large shape changes. In the latter case, also mechanics properties deformation process play a role for structure's energy efficiency. variational motion design, previously developed in group authors, allows identify paths between two given geometrical configurations that optimal with respect defined quality function. preliminary, academic setting this assumes every single degree freedom accessible arbitrary external actuation forces realize optimized motion. These (nodal) can be recovered posteriori. present contribution deals an extension constraint realized predefined set forces. prescribed length chances discrete, internal actuator elements. As additional constraint, static stability each intermediate configuration during taken into account. It accomplished enforcing positive determinant stiffness matrix.
