摘　　要：针对某装甲车辆自动装填系统中弹壳自动收抛装置的运动要求及空间约束问题,系统地提出了一种基于刚体导引的连杆机构的构型设计方法。基于实际工况,确定的连杆机构的刚体导引位置,建立基于二杆组的四连杆机构运动数学模型,应用Matlab计算软件,进行连杆参数设计计算,综合出具有期望运动曲线的四连杆举升机构,并进行机构的结构设计与分析,验证四连杆机构设计方法的有效性。所提出的设计方法为解析设计方法,设计过程直观、高效。For motion requirements and spatial constraints of automatic receiving and throwing device in automatic loading system for an armored vehicle,a mechanism design method of linkage mechanism based on rigid body guidance was proposed.Based on the actual working conditions,the rigid body guidance position of the linkage-type mechanism was determined,and mathematical model of four-bar linkage based on two-bar group was established.Using Matlab,the parameters of the linkage were calculated,and the four-bar lifting mechanism with expected motion curve was synthesized.The structure design and analysis of the mechanism were carried out to verify the effectiveness of the design method of the four-bar mechanism.The proposed design method is an analytical design method for four-bar linkage,and the design process is intuitive and efficient.
