Nodal balancing without trial weights by a modified Nyquist plot procedure. Academic Article uri icon

abstract

  • A linear model rotor response, depicted by model analysis, is considered and then compared to results obtained using a modified Nyquist plot theory. Modal unbalance is located by phase relations at the critical speed. A series of examples and applications follow which use the modified Nyquist plot procedure to correct first mode unbalance and show several ways of applying balance correction weights to allow greater flexibility in actual applications.
