摘要
给出了输入杆具有恒定转速的高速弹性机构稳态振动响应的一种高效解法。该方法适合于求解大型二阶周期时变的振动系统,计算精度和效率高,且节省高速内存,使在微机上进行高效的运动弹性动力分析与综合成为可能。对一弹性连杆机构进行了数值计算,并与有关文献的实验结果进行比较。结果表明,它们之间吻合很好。
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.
