摘要
为提高定制化门窗材分类堆垛效率,对双梁堆垛机的机构轨迹运动特征进行设计与分析。针对双梁堆垛机在堆垛过程中产生的运动轨迹动态干涉问题,提出以相对位置最优可行度进行判别分析的方法,在此基础上对不同的运动特性制定不同的运动策略,构建双梁堆垛机的协同规划模型,通过标准化运动学建模剖析轨迹运动特性,完成可行度规划模型优化联合机械系统动力学自动分析软件(Automatic dynamic analysis of mechanical systems,ADAMS)与Matlab Simulink建立运动学模型,对机械手的规划模型进行仿真验证。以ADAMS与Matlab Simulink的系统仿真技术对运动模型的解集进行数值分析验证显示,双机械手x轴方向位移轨迹无重叠区域,有效避免干涉碰撞风险;速度曲线连续无突变,加速度集中在2~4 m/s²,证实所建立运动模型的有效性。研究建立的双机械手运动规划模型可以有效地提升门窗材分类堆垛过程的效率,具有很高的可靠性,对于促进定制化门窗材的智能化分类堆垛具有重要意义。
Abstract
To enhancethe efficiency of classification, stacking and packaging of customized door and window materials, the mechanism trajectory and motion characteristics of double-beam stacker are designed and analyzed. Aiming at the dynamic interference problem of motion trajectory generated by the double-beam stacker during the stacking process, this paper proposes a discriminant analysis method based on the optimal feasibility of relative positions. On this basis, different motion strategies are formulated for different motion characteristics, and a collaborative planning model of the double-beam stacker is constructed. The trajectory motion characteristics are analyzed through standardized kinematic modeling to complete the optimization of the feasibility planning model. A kinematic model is established by combining ADAMS with Matlab Simulink, and the simulation verification of the manipulator's planning model is carried out. Numerical analysis and verification of the solution set of the motion model using the system simulation technology of ADAMS and Simulink show that the displacement trajectories of the two manipulators along the x-axis have no overlapping regions, which effectively avoids the risk of interference and collision. The velocity curve is continuous without abrupt changes, and the acceleration is concentrated in the range of 2-4 m/s², which confirms the effectiveness of the established motion model. The dual-manipulator motion planning model established in this study can effectively enhance the efficiency of the classification and stacking process of door and window materials, and has high reliability. The model is of great significance for promoting the intelligent classification, stacking and packaging of customized door and window materials.
