Obstacle performance of cobalt-enriching crust wheeled mining vehicle

A cobalt-enriching crust mining vehicle with four independent driven wheels was proposed. The influence of center-of-gravity position of mining vehicle on obstacle performance was studied. The results show that the mining vehicle has optimal obstacle performance with center-of-gravity position in the middle of suspension. A virtual prototype based on ADAMS software was built and its obstacle performance was simulated. Simulation results show that the mining vehicle with four independent driven wheels has excellent obstacle performance, the maximum climbing capacity is no less than 30°, the maximal ditch width and shoulder height are no less than wheel radius of mining vehicle. Thus wheeled mining vehicle is feasible for cobalt-enriching crust commercial mining.

泳渡台湾海峡视频技术方案

前言 “两岸携力横渡台湾海峡”活动是2014年我台制作调度中心接到的重要任务，由于场地的限制（3800吨级合富轮），不能吊装转播车上船，经过领导集体讨论，将任务交给了5CH EFP系统。此次活动原定于2014年8月16日由台湾新竹下水，经过72小时不分昼夜的直播，最终到达福建平潭，这么长时间的直播是电视直播史上没有的，所以对设备的可靠性提出了极大的考验。
