摘　　要：本文通过对圆盘剪剪切过程进行受力分析,建立圆盘剪剪切边界条件和约束条件。对厚度增加后的剪刃间隙重新进行优化调整,对厚规格板剪切过程进行了分析和对策实施,使中板厂厚规格Q345系列、AH32、AH36船板、Q460C等高强度板由20 mm增加到23 mm,提高了厚规格板的剪切能力。The article establishes the side limit conditions and the restraint conditions of the disc shear by analyzing the load on the disc shear during cutting, optimizes the knife gap against the increased thickness, analyzes cutting process of thick plate and takes counter - measures. Thus the maximum cutting thickness of high strength plate such as Q345 series, AH32, AH36 hull plate and Q460C is increased from 20 mm to 23mm, improving the cutting capacity for thick plate.
