对并联万向传动滑移时的自激振动进行了详细的数字仿真和特征值分析。研究了柔性联轴器和变速箱悬架橡胶弹簧的刚度和阻尼对自激振动的影响，明确了抑制自激振动的措施。通过改变板簧联轴器和齿轮箱悬挂橡胶弹簧的刚度和阻尼，对两种情况下的板簧联轴器进行了试验。计算结果与理论结果吻合较好。还对带齿轮联轴器的第三种情况进行了试验。测量了有自激振动和无自激振动两种情况下的平均总牵引力/总驱动轴载荷，结果表明，后一种情况下可获得较大的μa。
Detailed digital simulations and eigenvalue analyses of self-excited vibration during slippage of parallel Cardan drives were made. The effects of the stiffness and damping of flexible couplings and gearbox suspension rubber springs were studied, and measures to suppress the self-excited vibration were clarified. Experiments involving two cases of a leaf spring coupling were made by varying the stiffness and damping of the coupling and the gear box suspension rubber spring. The results agreed well with theoretical results. Experiments for a third case with a gear coupling were also made. (average total tractive effort/total driving axle load) was measured for two cases with and without self-excited vibration, and it was shown that the latter case could attain a larger μa.
