Solution of inverse geometrico-static problem (IGP) for suspended rigid-flexible coupling parallel mechanism (RFCPM) driven by elastic thin rods [PDF]

open access: yesMechanical Sciences
Rigid-flexible coupling is the development trend of lightweight parallel mechanisms. Different from traditional rigid parallel mechanisms, although the flexible components are light in weight, the large elastic deformation generated by the mechanism will
