摘要/Abstract

摘要： 泥浆泵是石油钻机的心脏,曲轴是泥浆泵的关键部件之一。为实现泥浆泵的结构轻量化,对曲轴进行结构优化设计至关重要。将模型进行合理简化,并对结构进行理论分析;利用软件拓扑优化模块确定优化参数,建立响应面模型;应用多目标遗传优化算法进行优化设计,结合生产工艺提出了在曲轴法兰盘上开槽的方案。通过仿真试验得知优化后的曲轴与原设计曲轴性能相当,而减重效果明显。对传统设备部件利用现代优化方法进行结构轻量化设计,降低产品能耗,不失为一种提高产品市场竞争力的手段。

Abstract: The mud pump is the heart of an oil rig, and the crankshaft is one of the key components of the mud pump. To achieve the lightweight structural design of the mud pump, it is very important to optimize the structure of the crankshaft. The model is simplified and the structure is analyzed theoretically. The optimization module is used to optimize the parameters;and the response surface model is established. The multi-objective genetic algorithm is used to optimize the design; and the scheme of slotting on the crankshaft flange is put forward according to the production process. Through the simulation test, it is found that the performance of the optimized crankshaft is similar to the original design, and the weight loss effect is obvious. In order to reduce energy consumption of product and improve the competitiveness of the product market, the traditional equipment components can be designed by using modern optimization methods.
