Abstract

Abstract:

To solving the problems of severe vibration and poor stability of maize straw deep bury and returning machine during the field operation， the vibration characteristics and influence rules of the machine are studied. In addition， increasing its low-order natural frequency is taken as the goal to optimize the structure of the implement and improve its operating effect. First， the natural frequencies of the machines are extracted through finite element modal analysis. Secondly， through the field testing， the amplitude statistical characteristics and power spectrum of the eight test points on the machines are obtained to analyze their impact on the vibration characteristics of the whole machine. Finally， based on the ISIGHT multidisciplinary software platform， the sequence quadratic programming method is used to optimize the parameters of the main structure of the implements， avoid the main external excitation frequency and optimize the structure of the implement. The research shows that machine vibration is mainly determined by forward speed， its own structure， and the conditions of soil and ground surface. When the implements operate， resonance has occurred at the tail of the frame， the covering device and the suppression wheel have a certain adsorption effect on vibration. Through the analysis on power spectrum， the main frequency that affects the vibration of the implement is concentrated at 8~16 Hz， which is close to the first-order and the second-order natural frequencies. The optimized first-order natural frequency of the main structure of the whole machine is increased to 20.348 Hz， which effectively avoids the resonance. The field experiment shows that the optimized implements can reduces vibration and noise during operation， and the effect of the operation is good， which provides a certain theoretical reference for the design optimization of the maize straw deep bury and returning machine.
