The five degree of freedom mechanism is the important part of equipment in hypersonic wind tunnel. In order to solve the problems exposed during long-term and frequent using, technical improvements need to be done. The main content of the improvements includes renewing of control system, increasing of Y-axis motion speed, and improving of insulating heat board mechanism and cable renewing as well. The five-degree-of-freedom support mechanism has been checked out and applied to carry out a standard model test after technical improvements, the test results demonstrate that the performance of the support mechanism get improvement obviously, and the force measurement test results of the standard model are well which satisfy to the demand of national military standard.
