Optimization design of vibration reduction structure of intelligent transport trolley in hilly and mountainous orchards

Since hilly orchard roads are rough and the fruit transport vehicles have poor vibration reduction effects, fruits are often damaged due to severe vehicle vibration. In order to ensure the quality of fruit transportation in the orchard, it was necessary to optimize the design of the vibration reduction system of the intelligent transport trolley in hilly areas. First, according to the terrain and landform of hilly orchards, the excitation map of transport vehicles was constructed. By analyzing the suspension system, a two-stage vibration damping structure was designed for orchard transporter in hilly areas, and its parameters were optimized. Then the dynamic model of ADAMS was built to simulate and analyze its vibration reduction performance. The simulation results showed that the Z-direction and X-direction vibration reduction performance of the second-stage vibration reduction structure was optimized by 9.08% and 24.22%, respectively, compared with the most widely used vibration reduction structure at present. The second-stage vibration reduction performance after parameter optimization was optimized by 7.1% compared with that before optimization.
