摘要
以BRK500/37.5型乳化液泵滑块为研究对象,根据滑块在实际工作时的受力情况,对滑块的结构进行了重新设计。与传统的结构相比,该滑块的结构能够承受较大的载荷。然后利用UG软件建立滑块的三维模型,并导入到ANSYS WORKBENCH中建立滑块的有限元模型。对滑块进行结构强度分析,得出滑块在最大压力下的应力和应变值,找出滑块结构的危险点,并对其结构进行进一步改进。改进后的滑块所受到的应力应变值较小,能够满足正常工作要求。通过以上研究和分析,为乳化液泵的实体设计提供理论依据。
Taking BRKSO0/37.5 emulsion pump slide block as the research object, the structure of the slide block is redesigned based on the force condition of the slide block. Compared with the traditional structure, the new structure of the slide block can bear larger load. Then the three-dimensional solid model of the slide block is established with UG, and the model is added to the ANSYS WORKBENCH in order to establish the finite element model of the slide block. Through analyzing the slide block strength at the maximum pressure, the stress and strain conditions of the slide block are obtained, and the danger point of the structure is found out, and then the structure is improved. The stress values and strain values of the improved slide block are smaller, and it can meet the normal requirements. Above all, the results provide a theoretical basis for the physical design of emulsion pump.
