A redundant manipulator that can online clamp pipe was developed to track along a cylinder intersection curve. With an ultrasonic transducer mounted on its end-effector, the manipulator can perform welding seam inspection at pipe joint in nuclear industry. An inverse kinematics solution expressed in joint space was solved based on the combination of geometric method and D-H matrix transformation. Expression about joints variables was obtained based on the scanning parameters of pipeline. The analysis method and results can be widely applied for online trajectory planning of intersection curve scanning manipulators. 相似文献

中国核工业的发展初期,在执行“以军为主”方针的同时,就开始了民用核技术的研究开发工作。早在1956年,中国政府在制定全国科学技术发展远景规划中,就把原子能的和平利用列为一项重点任务。自七十年代以来,中国国防科技工业开始了军民结合的实践和探索,由只为国防建设服务转变为工业、农业、科学技术和国防四个现代化服务。中国核工业这一战略重点的转移,为民用核技术的开发与应用开辟了广阔的前景。 相似文献
