借助虚拟样机技术,对柔性导轨自动制孔系统进行三维造型设计,将模型导入ADAMS(Automatic Dynamic Analysis of Mechanical Systems)软件对其虚拟样机进行运动学和动力学仿真分析,评价其系统设计的合理性和可行性。通过对比分析,给出了制孔系统合理的驱动速度、加速度等运动参数。根据制孔系统动力学特性分析,发现该系统存在非对称驱动的问题并提出了相应的改进方案,为柔性导轨自动制孔系统的结构和运动方案优化、缩短产品开发周期以及降低开发费用提供参考,为飞机装配高效精密自动制孔奠定基础。

The three-dimensional model of the flexible track drilling machine is designed by the virtual prototyping technology.The model is imported into ADAMS(Automatic Dynamic Analysis of Mechanical Systems)software to carry out the kinematics and dynamic simulation analysis of its virtual prototype,and the rationality and feasibility of the system design are evaluated.Through the comparative analysis,the reasonable driving velocity and acceleration parameters of the hole making system are given.According to the analysis of the dynamic characteristics of the systems,the asymmetric driving problems in the system are found and the corresponding improvement scheme is put forward.It provides a reference to the optimization of the structure and motion scheme of the flexible track system,the improvement of the product development cycle time and the reduction of the development cost.It may build the foundation for the efficient assembly of the high-precision aircraft.
