[Application of sensitivity analysis method in mode analysis of hypergravitation training facility].
OBJECTIVE
To increase the natural frequencies of hypergravitation training facility.


METHODS
The natural frequencies of the hypergravitation training facility were modified by using sensitivity analysis method.


RESULTS
The natural frequencies of the hypergravitation training facility were improved by modification of physical and geometrical parameters of sensitive elements.


CONCLUSIONS
The computational results indicates that sensitivity analysis method is feasible.
