Abstract

This research investigates the optimal design characteristics of a class-2 triplex tower as a morphing boom. The topic is to compare how changing the height of the nominal straight configuration influences the limits of achievable shapes. The tower is allowed to change overall shape through actuation of the supporting cables in each bay. With struts and face cables of fixed lengths, the range of achievable equilibrium shapes for a given structure is considered. We further determine which configurations may be reached from an initial straight configuration without member collision. For towers of a given overall height, we investigate the trade-offs between the number of bays and the height of single bays, with respect to the range of achievable shapes and complexity. Actuation methods are also considered. The results provide insight into the optimal characteristics for a triplex tower with a large range of achievable shapes, considering design decisions regarding the height of single bays, the use of multiple bays, and actuator placement.
