多功能智能轮椅设计-结构外观设计与运动仿真

北京理工大学珠海学院2020届本科生毕业设计Multifunctional intelligent wheelchair design-structural design andmotion simulationAbstractIn an age of increasing population aging,frequent accidents and natural disasters,peoplewith limited mobility and physical disabilities are increasing.Wheelchairs have become partof the daily life of this group of people.Compared with ordinary wheelchairs on the market,users are more inclined to use multi-functional smart wheelchairs.In order to help this part ofthe demand group improve the quality of life,it is necessary to research a multi-functionalsmart wheelchair with relatively low price,adjustable posture,indoor navigation,andautonomous movement using a joystick.This article mainly studies the structural design and motion simulation of themultifunctional intelligent wheelchair.First,select the size of the wheelchair based on therelevant knowledge of ergonomics,then use Pro /E to three-dimensionally model thewheelchair and check whether there is interference between the parts,and then verify themodel design through the finite element analysis of ANSYS Workbench The rationality of theuse of Pro /E to simulate the motion of the wheelchair mechanism,and finally render theappearance of the wheelchair model through Keyshot,and finally build a movable and able toachieve the relevant functions for the motion control system and function module of themultifunctional intelligent wheelchair Platform.Keywords:multifunctional;intelligent wheelchair;structural design;static analysis;motionsimulation
