ADAMS and ANSYS based Mechanism Optimization of Multifunctional Sprayer and Performance Test

摘要

For significant differences in plant morphology at different growth stage after tobacco transplanting, using single boom sprayer leads to poor disease and pest control. This paper designed a multifunctional sprayer, to conduct boom spray to seedling stage, and to conduct tunnel spray to maturity stage. First introduced the overall structure of the sprayer, applied ANSYS modal analysis technology to optimize the deformation mechanism, and combined with ADAMS dynamic simulation to verify the reliability of the design. Then according to the designed parameters, the sprayer prototype was built. Modal test of deformation mechanism and field test of sprayer were carried out. Modal test showed that the first natural frequency of deformation mechanism was 9.8Hz after optimization, the deviation of frequency between analysis and modal test was less than 10%. Field test showed in seedling and maturity stage of tobacco prototype's working efficiency was closed to 1.225 and 0.687hm~2/h, leaves liquid coverage reached 89.7% and 92.8% respectively, and almost no damage to tobacco leaves.
