Abstract:

In this paper,first,a model describing the brake situation of large space manipulator was established to extract an integrated design criterion of brake friction pairs according to the safety requirements of large space manipulator. Then,with the moment stability and lifetime of the brake as the indexes, the equivalent radius and the spray depth of friction pairs were calculated,and a ceramic friction pair was designed. Moreover,a prototype of ceramic
brake and the corresponding experimental table were developed. The results indicate that it is feasible to design the brake friction pairs based on the integrated design criterion verified by the brake safety indexes.

Key words: large space manipulator, brake, ceramic, friction pair
