船舶甲板机器人可帮助船舶高效率除锈,并降低船员工作强度,减少安全事故发生。传统的船舶机器人监控系统只能查看机器人的所有工作状态参数,无法形象地展示机器人工作状态。本文在对虚拟现实技术充分研究的基础上,设计甲板机器人状态监测系统,并设计系统传感信息采集的硬件结构。构建基于虚拟现实技术的机器人工作状态智能监控系统,对系统中的碰撞检测技术以及虚拟交互实现方法进行分析。通过将机器人的状态实时反馈到虚拟场景中,有效实现操作者和机器人之间的实时交互,实现在线操控监测和离线教学的功能。 相似文献

The dynamic buckling of the main deck grillage would result in the total collapse of the ship hull subjected to a far-filed underwater explosion. This dynamic buckling is mainly due to the dynamic moment of the ship hull when the ship hull experiences a sudden movement under impact load from the explosion. In order to investigate the ultimate strength of a typical deck grillage under quasi-static and dynamic in-plane compressive load, a structure model, in which the real constrained condition of the deck grillage was taken into consideration, was designed and manufactured. The quasi-static ultimate strength and damage mode of the deck grillage under in-plane compressive load was experimentally investigated. The Finite Element Method (FEM) was employed to predict the ultimate strength of the deck grillage subjected to quasi-static in-plane compressive load, and was validated by comparing the results from experimental tests and numerical simulations. In addition, the numerical simulations of dynamic buckling of the same model under in-plane impact load was performed, in which the influences of the load amplitude and the frequency of dynamic impact load, as well as the initial stress and deflection induced by wave load on the ultimate strength and failure mode were investigated. The results show that the dynamic buckling mode is quite different from the failure mode of the structure subjected to quasi-static in-plane compressive load. The displacements of deck edge in the vertical direction and the axial displacements are getting larger with the decrease of impact frequency. Besides, it is found that the dynamic buckling strength roughly linearly decreased with the increase of initial proportion of the static ultimate strength P0. The conclusions drawn from the researches of this paper would help better designing of the ship structure under impact loads. 相似文献
