Structural Optimization Design of Body of Oil-Perforating Gun

In the design of structure of oil perforating gun, for on the depth of perforating gun blind hole diameter, and the gun body wall thickness design is the key technology, through the introduction of optimization design technology, under the condition of satisfy the use requirement, language APDL of ANSYS software parametric optimal design of several data, the minimum wall thickness can get a gun. And on this basis, the blind hole diameter and depth was studied the influence of the strength of perforating gun. Conclusion shows that with the increase of blind hole depth, blind hole gun gun with blind hole part of the equivalent stress increased significantly, the strength of the blind hole depth of perforating gun has a great influence, and the intensity of blind hole diameter has little effect.

Study on the Parametric Optimal Design of a Different-Speed Mixer

The mechanical analysis and parametric optimal design of a different speed mixer is presented in this paper. After mechanics analysis, the total transmission power is derived. According to the realistic design requirements, several design constrains are also described. After established the whole optimization mathematical model of the different-speed mixer, Sequential Two-point Diagonal Quadratic Approximate Optimization (STDQAO) algorithms is applied for the optimal design of the mixer, and obtained the minimum transmission power.

Parametric Optimal Design of Robot End-Effector Tool for Robot-Assisted Automatic Polishing System

In this paper the multi-objective optimization design of a preliminarily designed end-effector tool for robot-assisted automatic polishing system is presented. ADAMS and iSIGHT are integrated for the multi-objective optimization design, the overall procedure of which is shown in this paper. Design of Experiment is arranged before optimization. The global optimization methods provided by iSIGHT software- Exterior Penalty and Multi-Island Genetic are utilized to perform optimizing process. Simulation executed in ADAMS with model updating with optimized structural design parameters verifies the significance of the multi-objective optimization in improving the performance of preliminarily designed end-effector tool.
