【摘要】：本论文以自行式直臂高空作业车为研究对象,运用SOLIDWORKS、ADAMS等设计和分析软件,对高空作业车进行三维设计,建立高空作业车的运动动力学模型,通过设计各种油缸的周期速度变化对顺序、复合举升作业方式时围栏的速度和加速度进行运动学仿真,找出设计高空作业车的围栏速度和加速度既满足安全又高速的办法。介绍直臂高空作业车的基本结构和工作原理,利用SOLIDWORKS软件建立高空作业车的模型。将高空作业车在SOLIDWORKS软件中的模型导入ADAMS模块中,添加驱动和约束,对比在不同的油缸运动速度、工作臂顺序运动和组合运动等条件下对工作平台处的运动轨迹仿真分析研究,找出围栏处的运动范围极限数据是否满足设计目标。参考国标GB25849和欧标EN280、AS/NZS 1418,利用SOLIDWORKS软件测算在不同的额定载荷,臂架举升速度,行走速度下的稳定性数据并对比得出整机的动态和静态稳定性最小指数,路缘石和坑洼稳定性最小指数是否通过相关要求,并且通过实验数据对比验证计算方法的正确性,为高空作业车的稳定性计算方法提供理论方法。本文的研究为高空作业车的控制系统速度设计、运动范围仿真和稳定性计算等提供了方法,对于公司其他类型的高空作业车设计开发,具有借鉴意义。
[Abstract]:This paper takes the self-propelled vertical arm aerial work vehicle as the research object, uses the SOLIDWORKSX Adams and other software, carries on the three-dimensional design to the aerial work vehicle, establishes the motion dynamics model of the aerial work vehicle. Through the kinematics simulation of the speed and acceleration of the fence during the combined lifting operation, the method of designing the speed and acceleration of the fence is found to satisfy both safety and high speed through the design of the periodic velocity variation of various oil cylinders to the sequence, and the speed and acceleration of the fence when the lifting operation mode is combined. This paper introduces the basic structure and working principle of the vertical arm aerial work vehicle, and establishes the model of the aerial work car by using SOLIDWORKS software. The model of aerial work vehicle in SOLIDWORKS software is imported into Adams module, and the driving and constraint are added, and the simulation analysis and research on the motion trajectory of the working platform are compared under the conditions of different cylinder motion speed, sequential movement of the working arm and combined motion, etc. Find out whether the range of motion limits at the fence meets the design objectives. Referring to the national standard GB25849 and the European standard EN280 / NZS1418, using the software SOLIDWORKS to calculate the stability data under different rated loads, boom lifting speed and walking speed, and to compare the minimum dynamic and static stability indices of the whole machine. Whether the minimum index of the stability of roadway edge stone and pothole meets the relevant requirements, and the correctness of the calculation method is verified by comparing the experimental data, which provides a theoretical method for the calculation method of the stability of the aerial vehicle. The research in this paper provides a method for the speed design, motion range simulation and stability calculation of the control system of the aerial work vehicle. It has reference significance for the design and development of other types of aerial work vehicles in our company.
