Abstract
The stiffness is a crucial problem for a space manipulator. It is very difficult to construct a high stiffness space manipulator with limited mass since high stiffness manipulator usually requires high expenditure on mass and volume. A method of stiffness optimization was presented to improve the stiffness of a space manipulator with limited mass. First, the stiffness model was established. Then, an optimization algorithm based on mass allocation was proposed. Finally, the optimum proportion between component mass and dimension was calculated.
