摘　　要：针对某公司生产的QC11Y30×15000型剪板机工作效率低、系统压力响应慢等问题,推导了插装式电磁溢流阀的数学模型,分析其相关参数对系统压力响应的影响。建立AMESim仿真模型,研究了剪板机工作过程中系统建压和泄压的动态过程。结果表明,主阀弹簧刚度和旁置式阻尼孔对系统建压时间影响程度较大,控制盖板阻尼孔对系统泄压时间影响程度较大,但系统工作压力和系统总流量对系统建压、泄压时间影响程度均极小。According to the low working efficiency and slow pressure response of QC11Y30 × 15000 plate shearing machine, the mathematical model of the cartridge electromagnetic relief valve is established to analyze the effect of some related parameters on pressure response. Meanwhile, an AMESim simulation model is built to study the dy- namic characteristics on building and relieving pressure during the working process of plate shearing machine. The results show that spring stiffness of the main valve and adjacent damping hole have a great influence on building pressure in the system, damping hole of control cover plate has a great influence on pressure relief, but the pressure and the total flow of the system have little influence on both.
