Two kinds of 2-dof parallel mechanisms are proposed in this paper which can be used as the actuator for the plane sprayer.The direct and inverse kinematics solutions of the two kinds of mechanisms are derived on the end operating point and two workspaces are analyzed and compared.The kinematics models of the end operating point of two mechanisms are simulated by Matlab examples obtaining variation of kinematics parameters of these two mechanisms.The research of this paper provides the basis for the selection of mechanism,trajectory planning of the end operating point on the sprayer and offers some practical value for trajectory analysis and structure design of the plane sprayer.
