Comparison of different passive horizontal sprayer boom suspension set-ups

摘要

Existing boom suspensions are effective to reduce rolling boom motions, but reduction of horizontal boom vibrations is negligible. A prototype passive horizontal suspension is developed and different suspension set-ups are compared with regard to boom vibrations and spray pattern homogeneity. Boom vibrations are simulated with a non-linear finite element program. The corresponding spray pattern is obtained by combining the static spray pattern with the simulated boom movements. An appropriate passive suspension is able to almost halve the CV of spray deposition compared to a fixed boom.
