Let's label that two. It's still at constant pressure. 我们把这个标为II,它仍然是在恒压下。
Dynamical analysis was carried on the label deliver mechanism of the label machine using the mechanical kinetics principle and the moment equation of dynamic equilibrium was established. Then its mathematical model was inferred and the factors influencing the constant tension were analyzed. 运用机械动力学基本理论,对贴标机的供标机构进行动力学分析,导出动态力矩平衡方程,建立数学模型,分析了影响恒张力的因素。
