Cepstrum analysis on support porter engines
2013
By applying the cepstrum analysis principle to analyze the support porter engine vibration signals.Accordingly,the engine vibration signals contain double-transponder and half-transponder impact signals,respectively.These signals are consistent with the support porter rotational speed,engine water-gate switching,valve switching,piston reciprocating frequencies.For the purpose of engine noise and vibration reduction design,these factors can be considered.Therein,this approach sets a theoretical basis on the dynamic engine optimization design.
