Simulation of Wine Grape Plants Forced Vibration Based on Adams

The harvest of wine grape is separate wine grape from grapevine by vibrate grapevine. Using Adams software,kinematics and dynamics simulation experiment of grapevine was conducted,through analyzing experiment results,the best frequency and amplitude of vibration force was obtained. Firstly,the 3D model of grapevine was established based on Solid Works,then imported it into Adams. Thirdly,the model was flexible by Adams module Adams / View Flex; Exerting vibration force on 3D model to simulate the force condition of grapevine during the harvesting time by machine,then we got simulation curves of the inertia force of a grape F1 and the inertia force of a grape clusters F2 by changing the two influence factors,i. e the frequency and amplitude of vibration force by Adams software. Lastly,by analyzing the results of simulation test,we got that conclusion: the best combination of frequency and amplitude of vibration force to harvest wine grapes is: 600 Hz and 35 N,550 Hz and 45 N,500 Hz and 60 N,450 Hz and 75 N. Through the verification to vibration acceleration of wine grape,the conclusion of the simulation is credible.
