摘    要:为使海底行走机构具有良好的自主导航能力,完成深海复杂地形路径规划需建立一个合理的、基于多传感器实时监测信息的运动学模型。以复合轮式海底行走机构为研究对象,基于D-H坐标建模方法和深海复杂地形环境特征,推导出海底行走机构的运动学方程,得到车体的位姿信息,并利用MATLAB工具获得车体的运动学参数理论计算曲线。在运动学分析的基础上,利用ADAMS软件建立该行走机构的运动学仿真模型,得到车体的运动学参数仿真曲线。通过理论计算和仿真试验对比,验证了所建立运动学模型的正确性,并为该行走机构路径规划和运动控制奠定了基础。

Abstract: To enable submarine vehicle having a good autonomous navigation to complete the simulation test in deep-sea complex terrain and rough terrain path, it is required to establish a reasonable kinematic model based on multi-sensor of a real-time monitoring information. Taking composite wheeled submarine vehicle as the research object, based on D-H transform modeling method and the feature of complex topographical environment in deep sea, the kinematical equation of the vehicle of deep seabed was deduced and the gesture information of vehicle was obtained, and relevant kinematic parameters curves were gained by using MATLAB tools. Based on the kinematic analysis, using AMAMS software to establish the kinematic simulation model of the vehicle, the kinematic parameters curves were obtained. By comparing theoretical calculations and simulation experimental results the correctness of the established kinematic model was verified, laying the foundation for path planning and motion control of the vehicle.
