In order to align kiln axis, taking equal fatigue strength of tyre and axis deflection minimum as the optimization goal, an equal fatigue strength optimization model of kiln tyre was set up.

从窑运行轴线调整出发，以回转窑各滚圈疲劳强度相近及轴线偏差最小为优化目标，建立了回转窑滚圈等疲劳强度优化模型。

Second, the initial point and transfer time are same for different object relative orbit, and the minimum consumption of fuel is proportional to the expansion deflection.

不同膨胀系数时施加脉冲的时刻不变，最优的燃料消耗与膨胀变化量成正比；
