Abstract: High clearance sprayer (HCS) plays an important role in agricultural production. Considering HCS's higher utilisation and work environment, the characteristic analysis of HCS is studied. Therefore, a new whole simulation model of liquid solid coupling dynamics of HCS is built. In the detail, the mathematical models of kinetic energy, potential energy and dissipated potential energy are built with new whole vehicle mechanical model. Secondly, the differential equations of HCS nodes are set up. Then the nodes response curves of HCS total system are simulated. Finally, the influence of liquid variation on HCS nodes is analysed. With simulation results, the liquid fluctuation of liquid storage device is influenced by primary motion of HCS. The influence of flow rate on the stability of HCS nodes is significantly different. The stability of HCS is the problem to be settled urgently when the velocity and liquid flow are all changed and synchronised.

Keywords: HCS; high clearance sprayer; HCS nodes; liquid solid coupling; displacement amplitude; liquid variation.
