冷轧钢管机的送进——迥转机构具有较大的质量及加速度,因而在冷轧钢管时此机构产生强烈的振动响应,其动应力幅对轧机的工作可靠性与使用寿命有较大的影响。对于冷轧钢管机固定机座的送进——迥转机构可以简化为三质量——弹簧的动力学模型,由子冷轧钢管工艺阻力是随时间而变的函数,故其振动响应的微分方程的解包括通解 Cold-rolled steel pipe feed - turn around the mechanism has a greater mass and acceleration, so in the cold-rolled steel pipe when the agency has a strong vibration response, the dynamic stress amplitude of the rolling mill work reliability and service life are larger Impact. For cold-rolled steel tube fixed base of the feed - turn to turn the body can be simplified to three-mass - the spring dynamics model, the sub-cold-rolled steel pipe process resistance is a function of time change, so its vibration response differential equation Solutions include general solution
