为了满足海上作业日益增长的重型起重任务的需要,在短期内应设计制造出新设备来。当然,陆上设备的使用经验被用来开发这类新设备。结果所形成的破坏促使有关当局把许多海上起重机的使用能力降低50%。

With European Laser Facilities such as the Extreme Light Infrastructure(ELI) and the Helmholtz International Beamline for Extreme Fields(HIBEF) scheduled to come online within the next couple of years, General Atomics, as a major supplier of targets and target components for the High Energy Density Physics community in the United States, is gearing up to meet their demand for large numbers of low cost targets. Using the production of a subassembly for the National Ignition Facility's fusion targets as an example, we demonstrate that through automation of assembly tasks, the design of targets and their experimental setup can be fairly complex while keeping the assembly time and cost as a minimum.A six-axis Mitsubishi robot is used in combination with vision feedback and a force–torque sensor to assemble target subassemblies of different scales and designs with minimal change of tooling, allowing for design flexibility and short assembly setup times. Implementing automated measurement routines on a Nikon NEXIV microscope further reduces the effort required for target metrology, while electronic data collection and transfer complete a streamlined target production operation that can be adapted to a large variety of target designs. 展开更多
