Simulation and verification of the working process of a disc grass mower based on virtual prototyping technology

The virtual prototype of a disc grass cutting machine was designed by Solid Works, and its working process was simulated by ADAMS(Automatic dynamic analysis of mechanical systems) to obtain the blade rotation trajectory. The orthogonal experiment had three factors and three levels and a multi-index model was obtained. To determine the best value of the movement parameters, the comprehensive balance method was adopted.When the forward speed was 2.74 km·h-1, the rotation speed was 2000 r·min-1, the number of the blade pieces was 3, and the area of repeat cut and missed cut were effectively reduced. The motion parameters and performance index of the solid prototype were tested in the field, and the results showed that the simulation data were reliable and significant for selection of motion parameters of the disc orchard grass cutting machine.
