基于VB的钢筋切断机通用动力学计算模型

Dynamic calculating model based on VB for reinforcing steel cutting machine

针对典型钢筋切断机的结构建立了钢筋切断过程中的通用动力学计算模型,并采用VB程序编制了执行机构的运动分析程序、各构件转动惯量的计算程序以及电机真实运动分析的总程序.依据上述计算模型和程序对GQ40型钢筋切断机进行实际计算,当切断直径为40 mm的45#圆钢时,电机的速度降幅为12.7%,与实测结果13.1%相吻合,表明所建立的计算模型和编制的相关程序是正确的.

A dynamic calculating model for reinforcing steel cutting machine was set up VB are used to perform mechanism＇ s movement analysis program, part＇ s moment of inertia calculation program, and real movement of electric motor calculation program, According to the above programs the movement parameters of GQ 40 reinforcing steel cutting machine are calculated. For example, when cutting off steel bar of type 45 which has diameter 40 mm, the speed of moter drops 12.7%, which is anastomose with measuring fact of 13.1%. The result proves the calculation model is correct.
