Analysis of Dynamic Characteristics of the Actuator Assembly Mechanism for Automatic Navigation Transplanter
To investigate the reliability of the steering actuator assembly scheme based on U-shaped clamps for the agricultural auto-matic navigation test platform,an analysis of its dynamic characteristics was conducted.The simulation results showed that the first two modal natural frequencies of the assembly mechanism are relatively low,at 57.403 Hz and 62.044 Hz respectively.The vibration modes are mainly characterized by left-right oscillation along the Y-axis and forward-backward oscillation along the X-axis of the steering actuator and assembly mechanism.Vibration excitations at these two frequencies should be avoided in low-frequency vibra-tion sources.The impact load in the Y-direction significantly affects the stability of the assembly mechanism.
