不同侧向间隙下圆盘剪剪切数值模拟与实验研究
Simulation and study of rotary shear cutting under different lateral gap
摘要
Abstract
Q235 steel was taken as example and by using the software of DEFORM-3D, the procedure of rotary shear cutting 20 mm steel plate was simulated in different lateral gap is 0.5mm, 1mm, 1.5mm, 2mm.The paper analyze on the effect the different lateral gap on cutting force and the stress distribution of the steel plate and the quality of cross section after shearing.The results of simulation shows that it will increase the cutting force, lead to uneven stress distribution and adversely affect the quality of cross section no matter what the lateral gap is too large and too small, so the best lateral gap is 1mm when cutting 20 mm steel plate.So in the shear testing the lateral gap is set to 1mm according to the field experiment.The test results show that the section cutting quality of steel plate is good when the lateral clearance is 1mm, which proved the accuracy of the FEA simulation result and the effect regularity of lateral clearance on shearing process.关键词
