Design of Integrated Dual Spiral Spring and Rotary Hydraulic Damper System for Torsional Vibration Damping in Pesticide Sprayer Gearbox

Torsional vibrations pose a significant challenge in various industrial sectors, necessitating effective damping solutions to mitigate their adverse consequences. Mitigating vibrations stands as a fundamental approach to extending the operational lifespan of machinery. This paper presents a comprehensive study on the design and implementation of an integrated dual spiral spring with a rotary hydraulic damper, aimed at attenuating the inertia forces generated by an oscillating nozzle arm within a dual action oscillation gearbox utilized in pesticide sprayers. The research encompasses a detailed investigation into the kinematic linkage design and the determination of the system forces within the gearbox to optimize the damping performance. The theoretical design of the spiral spring is carried out to ascertain the maximum moment it must endure to effectively damp torsional vibrations. The integral components of the dual spiral spring system, including the spiral spring base, retraction lever, and bell crank, are meticulously modeled. Subsequently, a comprehensive analysis of these components is conducted using Ansys Workbench-16.0, a widely recognized tool for mechanical analysis. This research contributes valuable insights and practical solutions to the pressing issue of damping torsional vibrations in dual action oscillation gearboxes for pesticide sprayers. The outcomes presented herein have the potential to not only enhance the operational efficiency and longevity of such equipment but also find application in diverse industrial settings grappling with analogous vibration-related challenges.
