Study On Branch-Avoiding Mechanism Of Remote Control Pruning Machine

The remote control pruning machine is one kind of portable machinery which is used to prune branch around tree trunks achieve through wireless remote control. In the process of spiraling climbing around the trunk,the pruning machine is pruning by chain saw. This thesis first introduced the working principles of the remote control pruning machine,And proposed the necessity to design the branch-avoiding mechanism .In the thesis,mainly study on the branch-avoiding mechanism of the remote control pruning machine ,the main work is following:1,Introduced the main composition of the branch-avoiding mechanism, analyzed main function and the movement situation every parts. And finally proposed the principle of design of the pruning machine.2,Analyzed the three methods and its characteristic of Kinematics simulation for the branch-avoiding mechanism with Matlab/Simulink, On this basis, simulated the movement of crank swinging up.3,According to the design request for the branch-avoiding mechanism, the multi-objectives function optimization mathematical model is established as Minimum height(H1) at smallest working load(P1),and the minimum weight of spring. Finally,I optimized the spring by Genetic Algorithm with GOAT toolbox of Matlab and gained the optimized result.
