Flapping noise analysis of piston mechanism for R4105ZD diesel wood chippers

Abstract

Flapping noise analysis is performed for the piston mechanism of R4105ZD diesel wood chippers based on the multi-body kinetic analysis, transient vibration analysis and acoustic-solid coupling analysis. Noise sound pressure variation curves and sound pressure level distribution law are obtained, which provides a theoretical basis for reducing the noise generated by the R4105ZD diesel wood chippers in the working process
