摘要

对直线电机驱动的单侧变截面辊弯成形系统进行了运动分析.应用正解法分析了末端轧辊的位移、速度、加速度等受直线电机相关参数的影响,并列出了相关的运动方程.应用Matlab语言描绘出了末端轧辊的运动参数的变化曲线,通过曲线对比,分析了直线电机的各个运动参数的变化对末端轧辊速度、加速度等影响;分析并探讨了有关的结构参数的变化对末端轧辊的位移、速度、加速度的影响.%The motion of a system driven by a linear motor for a rollforming with one-side variable cross-section is ana-lyzed.With the forward kinematics, the influences of the motor parameters on the displacement, velocity and accel-eration of the roll at the end are analyzed, and corresponding motion equations are established.By using the Matlab language, the variable curves of the motion parameters of the roll at the end are depicted.The influences of the mo-tor' s variable motion parameters on the velocity and acceleration of the roll at the end are analyzed by comparing the curves.The influences of the corresponding variable structural parameters on the displacement , velocity and ac-celeration of the roll at the end are discussed.
