摘要
插床中插刀的上下往复运动直接关系到工件切削的效率.建立插床六杆机构的矢量模型,用Matlab/Simulink中的积分模块建立仿真框图,设置合理的初始条件,将插刀的位移、速度和加速度曲线规律可视化.对机构作计及摩擦力的静力分析,通过摩擦圆和相对角速度判断运动副所受摩擦总反力的方向,依次求解各个构件的静力平衡方程式,得出主动件上所能克服的等效阻力矩,并用Matlab软件得出等效阻力矩随时间变化的规律.
In the slotting machine the slotting tool moved up and down which is directly related to the cutting efficiency for workpiece. The vector model of slotting machine six bar linkage is established,matlab / simulink integral module method is used to establish the simulation diagram,reasonable initial conditions are set up to visualize displacement,velocity and acceleration curve. The friction force is always tangent to the friction circle,and its moment to hinge center is contrary to the relative angular velocity,the static equilibrium equations are solved of each components. Ultimately the active parts should be applied to the driving moment on the law of the change over time.
