摘　　要：为实现平面非圆曲线零件轮廓相对确定方向的线速度稳定不变(简称恒速),建立了控制运动的数学模型后,需从理论上验证模型应用于实际的可行性。基于VB设计的恒速运动仿真系统选择偏心轮为试件,参数可任意调节,用数学模型控制模拟实际运动状态,动态显示运动速度并计算误差。应用仿真系统在常用参数范围内计算速度误差,结果表明运动的相对误差较小,说明数学模型控制平面曲线零件的运动可以实现基本恒速。To achieve non-circle curve parts plane contour determines the direction of line speed and stability constant （constant speed for short）, established after control mathematical model of movement, needed in theory verification model applied to the practical feasibility. Selecting constant speed motion simulation system based on VB design eccentric specimen, parameters can be adjusted, using mathematical model control simulation of the actual state of motion, dynamic display speed and to computation errors. Application simulation system in the common parameters calculation error, results showed that movements of relative error smaller, control plane curve part of mathematical model for description of movement can achieve constant speed.
