Abstract: The vibration characteristics of the tendon-based parallel robot for processing are
presented. Firstly, the free vibration equations of the robot on the stable position and orientation
were modeled, and secondly the natural frequencies were deduced from the transformation of
principal coordinates into modal coordinates. Next, cutting-force model was introduced and the
solutions of the forced vibration equations were obtained from the Runge-Kutta method, where
the minimum natural frequency was taken as basis of the time step that was important for
computation convergence. Lastly, the algorithm was verified by simulations, also including
solution transformation of time domain into frequency domain by Fast Fourier Transformation
(FFT). The vibration properties could be manifested clearly by the solutions in frequency domain.
The results show that the eccentricity and the mass of the moving platform are the important
factors to make system instable in certain excitation frequency. © (2013) Trans Tech Publications,
