For the efficient long-range non-destructive health examination of pipes, ultrasonic guided wave NDT has been widely used. The objective of the research presented is to investigate the feasibility of detecting defect in high-pressure pipe using ultrasonic guided wave NDT technology based on magnetostrictive effect. Both theoretical calculation and experimental analysis for one standard pipe are carried...
A path-tracking intelligent optimizating for the so called LHD (load-haul-dump) units used in underground mining is proposed in this paper.It establishes the machine hand model system for manipulator of this vehicle. Find the minimum energy consumption track. But the actual working track of the bucket is different from the ideal track in the actual work condition. So this paper exploits the measure...
In order to realize networked management of scientific instruments, a distributed monitoring system for their working status was developed. There were two solutions involved to acquire the working status data of scientific instruments. One is to detect their characteristic physical signals with sensors, and the other is to detect working parameters of their control software on their workstations with...
