高速烟组剔除机构刚柔耦合动力学优化研究OA

[Background and Objective]The tobacco rod rejection mechanism is a key unit in cigarette packing machines used to eject nonconforming cigarette groups.Due to its high operating speed and large inertial impacts,the mechanism is prone to significant vibration,which adversely affects stability and reliability.Therefore,optimization of its dynamic response is required.[Methods]A rigid-flexible coupled dynamic model of the tobacco rod rejection mechanism was established using ADAMS and Apex software.The dynamic responses and key performance parameters of the mechanism were systematically analyzed and optimized.[Results]The vibration generation mechanism of the tobacco rod rejection system was clarified.By adjusting the material properties and structural dimensions of critical components,the dynamic performance of the mechanism was significantly improved.The optimized design reduced the maximum vibration displacement by 43.5％.[Conclusion]The rigid-flexible coupling dynamic optimization method effectively enhances the stability and reliability of the tobacco rod rejection mechanism and demonstrates its feasibility for application in the design and optimization of tobacco machinery.
