以偏置单盘转子为研究对象,用传递矩阵法建立了含有加速度项的瞬态运动方程,并且以Newmark-β积分法求解,编程模拟出系统的突加不平衡瞬态响应。该方法考虑了加速度、阻尼对瞬态响应的影响。结果表明:单盘转子系统在运转时突加不平衡后会引起较大的幅值震荡,最终趋于稳定;突加不平衡引起震荡的幅值和最终稳定值都随突加不平衡量的增大而增大,近似成正比例关系。
Taking bias single disc rotor as the research object, the transient motion equation with acceleration term is established by transfer matrix method, and solved by Newmark-β integration method. The sudden and unbalanced transient response of the system is simulated by programming. The method takes into account the effects of acceleration and damping on the transient response. The results show that when the single disk rotor system is in unbalanced operation, it will cause large amplitude oscillation and finally stabilize. The amplitude and ultimate stability value of shock caused by sudden unbalance increase with the increasing unbalance Large and increased, approximately proportional to the relationship.
