Abstract

In view of the poor smoothness of a highland gap sprayer, a virtual prototype simulation model of an ADAMS software high gap sprayer was established.Based on the harmonic superposition principle, an E grade stochastic road model suitable for the field operation of high altitude gap sprayer was established.Considering the effect of liquid sloshing on the operation of the highland gap sprayer, the forced oscillation model of liquid in a medicine box was established, and its random acceleration excitation was studied.The results show that the degree of liquid sloshing is greatly influenced by lateral and longitudinal acceleration.According to the forced sloshing model of the liquid in the medicine box, a highland gap atomizing locomotive fluid coupling model was established, and the ride comfort of the highland gap sprayer under different speeds, different liquid filling rates, and different suspension parameters was studied.The influence rule of various factors on the smoothness of the highland gap sprayer was obtained, and the optimal suspension parameters were optimized to improve the operation of the highland gap sprayer.
