| Abstract: | An efficient numerical method is presented for determining the steady-state vibration response of high-speed flexible mechanisms operating with constant input rotating speed. The method is suitable for solving second order linear differential equations with time-dependent and periodic coefficients for large vibration systems. This method can save high speed internal memory and makes it possible that the kineto- elastodynamic analysis and synthesis of mechanisms are calculated efficiently on microcomputer. The steady-state vibration response of a planar four bar mechanism is investigated using the method. The calculated vibration response is in good conformity with previous experimental results. |
