以新型装配式建筑墙板安装机为研究对象,分析了机构构型及具体实施方式,建立了动臂起落机构运动学、动力学数学模型,求解了油缸最大负载与尺度参数的函数关系;以动臂起落机构各构件尺度参数为设计变量,以动臂抬升过程中动臂油缸最大负载最小为目标函数,以整机布局、机构奇异性、几何约束等为约束条件,建立了动臂起落机构尺度优化模型;基于复合形法并通过Matlab软件进行迭代计算,得到了动臂起落支链各构件最优尺度参数,使得动臂起落油缸最大负载降低了11%左右,有效提升了机构的动态性能;基于Creo软件分别建立了优化前、后装配式建筑墙板安装机虚拟样机,并进行动力学仿真分析,验证了尺度优化模型的正确性。研究为装配式建筑墙板安装机性能提升提供了依据。
Taking a new type of prefabricated building wall panel installation machine as the research object
the mechanism configuration and specific implementation are analyzed
the kinematic and dynamic mathematical models of the boom landing mechanism are established
and the functional relationship between the maximum load of the cylinder and the scale parameters is solved. Taking the size parameters of each component of the boom landing mechanism as the design variables
taking the minimum maximum load of the boom cylinder during the boom lifting process as the objective function
and taking the overall machine layout
mechanism singularity
geometric constraints and other constraints as the constraints
the boom is established. The scale optimization model of the landing mechanism
based on the composite shape method and iterative calculation through Matlab software
the optimal scale parameters of each component of the boom lift chain are obtained
and the maximum load of the boom lift cylinder is reduced by about 11%
effectively improving the dynamic performance of the mechanism. Based on Creo software
a virtual prototype of the prefabricated building wall panel installation machine before and after optimization is established
and dynamic simulation analysis is performed to verify the correctness of the scale optimization model. This research will be used for prefabricated building wall panel installation and provides a basis for improving the performance of the machine.
