Overall Design And Dynamics Simulation Of Electric Crawler Telecontrolled Hedge Trimmer

Based on the premise of energy saving and environmental protection,this paper designs a pure electric crawler type remote control hedge trimmer based on the maintenance demand of highway green belt.Improve the efficiency of greening belt pruning work and pruning quality,and reduce labor intensity.Applying new energy ideas and technologies to hedge trimmers solves environmental pollution problems and contributes to green sustainable development.At the same time,it provides design basis for the same industry and promotes the development of the industry.By analyzing the working conditions.The overall scheme of the hedge trimmer is mainly composed of the walking system,the trimming system,the transmission system,the remote control system and the monitoring system,so as to ensure that the systems can cooperate with each other to form a complete machine solution that meets the design requirements.According to the design route,the overall scheme design of the hedge trimmer was first completed,including the analysis of the working environment and working objects and the functional realization requirements of the hedge trimmer.The designed hedge trimmer is the crawler chassis,and the cutter can be lifted and lowered to meet the working conditions.,operational capabilities and efficiency requirements.Secondly,based on the overall design scheme,the crawler chassis running device of the whole vehicle is designed with reference to relevant standards.By analyzing the working object,a lifting tool holder is designed to meet different working requirements and the tool is properly selected.The space layout scheme on the chassis of the vehicle is determined,and a battery box for heat dissipation is designed to place and protect the battery.Static stability analysis of the vehicle.Finally,the dynamic simulation model of the crawler chassis and the whole vehicle was created.The pavement models such as flat and slope were created in the simulation software.The vehicle dynamics model was put into the pavement model of different typical working conditions,and the drive was driven in the crawler chassis.Different speed functions are added to the wheel to perform kinematics and dynamics simulation of each typical working condition.In this paper,the overall design of the hedge trimmer is completed,and the typical working condition dynamics simulation analysis is carried out.The simulation results of thestraight-land straight and slope driving conditions show that the vehicle is stable and the motion parameters are consistent with the theoretical design;The simulation results of the machine in differential steering and in-situ revolving conditions can be seen that the vehicle’s driving performance meets the requirements when the hedge trimmer turns and rotates,and the driving state is stable;according to the pre-tensioning force of the tensioning device,the driving performance and state of the hedge trimmer The effect determines the appropriate pre-tensioning force of the track chassis tensioning device.
