一种双电机驱动的无人机机械爪结构设计与有限元分析
Design and finite element analysis of a dual-motor-driven UAV mechanical claw structure
摘要
Abstract
In response to the difficulties in catching irregular objects and the problem of single grasping angles for mechani-cal claws carried by small multi-rotor aerial vehicles,this paper takes the catching mechanical claw carried by multi-rotor aerial vehicles as the research object and designs a rotatable four-finger mechanical claw.First,the mechanical claw model was established in Solid Works and imported into ANSYS Workbench for finite element simulation of the main components of the mechanical claw.Static mechanical analysis was conducted on the push-pull crank,transient dynamic analysis was per-formed on the meshing gears,and modal analysis and topological optimization analysis were carried out on the claw bracket to obtain the total deformation and stress distribution cloud diagrams of each component.The analysis results show that dur-ing the catching process of the mechanical claw,the maximum stress of the push-pull crank is 7.46 MPa,which is much less than the material yield strength,and the deformation is less than 1 mm;the first-order natural frequency of the claw bracket is 59.833 Hz,which is much greater than the meshing and rotation frequency of the gears;the optimized claw bracket a-chieves lightweight design while ensuring basic mechanical performance,with all parts meeting the work requirements and making rational use of materials,reducing the impact of the claw movement on the rotor UAV,and providing a reference for the analysis and optimization of similar structures such as mechanical claws carried by rotor aerial vehicles.关键词
