Abstract: Loading test stand for navigating machine is used to simulate dynamical loading from both normal and reverse directions on navigating faces, aimed at conducting performance test for navigating system and control system under reverse operating mode. It uses pneumatic power to realize reverse loading. High loading strength, high symmetry, high Linearity and small loading elements are the basic requirements for the design of this stand. By using the balance technology of robots, we solved the above key technologies,and successfully designes a test stand which is believed to be the first in our country.
