Simulation Analysis on Flexible Track Drilling Machine Based on ADAMS

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.
