| Abstract: | By using finite element method,the power spectral density analysis of the BKX-I parallel kinematic machine based on Stewart mechanism was made.The displacement stochastic vibration response curves of all nodes on this PKM which is along the variable axis were gotten.On this basis,the disciplinarian of displacement stochastic vibration response was analyzed and the characteristics and scalar of response were confirmed. |
