盾构机；复合地层；非线性；刀盘驱动转矩；堵转

By considering torque characteristics of variable-frequency motors and mesh stiffness as well as backlash nonlinearity in gear transmission,a dynamics model for the cutting system of shield tunneling machine with redundant drives was established. The fluctuation characteristics of torque loads and dynamic cutterhead driving torque in composite strata were analyzed.

复合地层掘进扭矩载荷突变是造成盾构机掘进过程中堵转停机的直接原因，考虑盾构机刀盘驱动变频调速电机特性、转矩传递过程中齿轮啮合刚度及齿侧间隙等非线性因素，建立冗余驱动的盾构机刀盘切削系统机电耦合动力学模型；针对典型复合地层地质条件，对盾构机在上软下硬地层掘进过程中刀盘驱动转矩动态特性进行仿真分析。

He put on first the aerial breeze, then threw over himself light as a flaming mantle, and over this light a covering of water; he surrounded himself with gusts of wind, took light as his lance and shield, and cast himself downward toward the line of danger.

他提出的第一个空中的微风，然后扔在自己轻如燃烧的地幔，并在此轻覆盖的水；他包围自己的阵风风力，光了他的长矛和盾牌，并自诩为对向下行的危险。

Su Dongpo laughs: Say so according to you, cremate of pen, Chinese ink, the person that makes illiterate is drunk go down, the meeting when he stands writes an article; The shield that lets what a craven licks fencing Kuai, he rose bravely immediately, call an a very ugly person to hear the dangler that Xi Shi has worn, become charming immediately rose?

苏东坡笑道："照你这样说，把笔、墨烧成灰，让一个不识字的人喝下去，他便立时会写文章了；让一个胆小鬼舔一舔樊哙的的盾牌，他便立刻勇敢起来了，叫一个丑八怪闻一闻西施戴过的耳环，便立刻变得俊俏起了？"

The death ray guard shield energy finally exhausts.

死光护罩的能源终于耗尽。
