Optimizes and analyzes the gear set structure of hydraulic power pliers used in continuous loading unloading operations. The optimization design process was elaborated detail, including selection independent variables, determination constraint conditions, establishment objectives fitness functions. simulated annealing particle swarm algorithm (SAPSO) for design, results showed that total volume reduced by 17.1%. Finally, strength optimized verified through finite element analysis, met actual...
Well workover is an essential operation process in oilfield, and tubulars, overhauling the transportation of between pipe racks wellhead platforms forhas long been a big problemoil rods other tubing. Due to inadequacy devicesthe related tubulars transportation, there are problems such as low efficiency insufficient safety operationsheavy workload, lifting lowering. Some domestic oilfields still use manual or semi-automated mode, which easy cause wear tear tubing, hazards. In order solve...
Aiming at the problems of high labor intensity, low efficiency and poor safety manual operation in oilfield well repairing operation, a new type tubing grasping robotic arm machine is designed, which aims realizing automation lifting lowering operation. The suitable for both straight inclined workover operations, capable completing such actions as grabbing, moving, centering discharging tubing. article elaborates structural design arm, including key components bottom rotating hydraulic...
The cutter-workpiece engagement (CWE) is an important basis for accurately predicting milling force and vibration of machining system, which can be dramatically affected by the complex tool path, variable part allowance various profiles. paper presents a fast calculation method CWE during peripheral process based on Boolean operation. A second-developed simulation environment embedded kernel program with aid commercial CAM established. In computing model, locally past-cut material entity...
The force of ballastless track on bridge is relatively complex. Smooth running and safety high-speed train directly influenced by the stability CWR. Laws deformation CWR become a hot issue for scholars both at home abroad in researches. Based finite element method, theory bridge-rail interaction practical situations, space coupling model CRTS I type simply supported with length 6×32 m established. Characteristics rail, slab, base plate under effect temperature load have been researched,...
