摘要
由于工厂生产区域通道的狭窄,留给物料牵引车的通行空间有限,需要物料牵引车系统在运行时,不仅要追求节拍上的高效,也需要后料车的运行轨迹与前料车的运行轨迹接近.本文以吉利自研的轮式物料牵引车为研究对象,简化料车的轮式结构,对其进行运动学分析,并导入ADAMS中建立虚拟样机,进行动态分析和仿真模拟,分析料车脚轮在底部连杆的作用下是否满足阿克曼原理.进而将各连杆进行参数化设计,采用平均数法和均方根法,对各连杆尺寸进行优化分析,得出最优尺寸.意在使优化后的尺寸,满足阿克曼原理,提高轮式物料牵引车对狭窄通道的通过性,也为工厂效率提升提供了依据.
Abstract
Due to the narrowness of the factory production area channels,the space for materials tugger tain to pass is limited.When the materials tugger tain system is in operation,it is necessary to pursue not only efficiency in terms of pace,but also the proximity of the rear vehicle's trajectory to the front vehicle's trajectory.Taking Geely's self-developed wheeled materials tugger tain as the research object,the wheel structure of the vehicle is simplified and its kinematics are analyzed.A virtual prototype is established in ADAMS for dynamic analysis and simulation.The analysis focuses on whether the foot wheels of the vehicle satisfy the Ackermann principle under the action of the bot-tom linkage.Then,the parameters of each linkage are designed and optimized using the average method and the root mean square method to obtain the optimal dimensions.The goal is to make the optimized dimensions satisfy the Ackermann principle,improve the passing ability of wheeled materials tugger tain in narrow channels,and provide a basis for improving factory efficiency.
