内扭转

With the plane on its final approach to Owen Roberts Airport a sudden sea of craning heads erupted, trying to take in everything visible through the small windows and, though Id seen it a million times, I still couldnt resist contorting my body from the aisle seat to catch the view.

Rotational modes are independent of the transverse support stiffnesses of the carrier, ring gear, and sun gear. Translation modes are similarly independent of the rotational support stiffnesses. Large contact ratio do not mean lower mesh force. If either the number of sun or ring gear is not multiple of planet gear, system will run effectively, with lower impaction of tooth mesh in and out.

研究表明：扭转支撑刚度的变化影响系统的转动模态，径向支撑刚度的变化影响系统的位移模态；齿轮间重合度大并不等于轮齿间的受力情况好；行星轮与内齿圈齿数不为行星轮个数的整数被时，轮齿的啮入、啮出对系统的冲击小，系统的效率高。

The products can substitute solid clay bricks, avoid damage to the earth, curb the emission of CO2, and protect the environment and farmland. Other special characteristics include being light weight (about 1/3 of a double side plastering wall), having a thickness of 9 to 12 cm, having fire resistance and thermal insulation (A-level non-combustible insulation material), being convenient for construction (plate-type assembling and dry construction), and being cost effective (An enclosure wall of this material can reduce construction costs by 15% to 20%). It has advantages over solid clay bricks in terms of weight, energy-saving capacity, recycling and environmental protection.

产品不仅可以替代实心粘土砖，扭转烧砖毁地局面，遏制CO2的排放，保护环境和耕地，而且具有自重轻（约为双面抹灰墙的1/3）、墙体薄（厚9~12M）、防火与保温、施工便捷（采用板块式拼装、干式作业）、投资省（利用其作为建筑围护内外墙，可节省建筑投资10%~15%）等特点，在&轻质、节能、利废、环保&等方面均优于实心粘土砖。

BW-WJ universal angular corrugated compensator is made up of structures such as one (or more the two namely composite universal angular type) bellows, forelock, axis, hinge plate, universal loop and standing board etc. It can absorb angular displacement in any plane and bear the pressure or thrust of the bellows. When large compens-ation is required, two or more compensator can be assembled and utilized in series. Besides, the product can also be pre-pressed, pulled or reversed when installed.

BW-WJ型万向角向型波纹补偿器由一个（或二个及以上，即复式万向角向型）波纹管、销、轴、铰链板、万向环和立板等结构件组成，能吸收任意一平面内的角位移并能承受波纹管压力推力的膨胀节，当需要大补偿量时，可采用两个或以上组合分段串联使用，并对产品预压缩、拉伸或扭转安装。

Wind or turn in volutions, esp. in an inward spiral, as of snail.

There are many problems in the carling forming and unloading processes such as expand and shrink of U section wall, the torsion of U section and the warp of carling head.

针对纵梁冲压成形及卸载后发生的U型截面侧壁的外扩、内缩、扭转以及纵向端头翘曲等问题，首先分析了纵梁的成形及回弹变形机理，利用仿真分析软件KMAS进行了数值模拟并采用半解析、半实验方法研究了纵梁底面翘曲，找出模具结构的最佳方案。

There are many problems in the carling forming and unloading processes such as expand and shrink of U section wall, the torsion of U section and the warp of carling head. These problems are concerned by the carling factories and do not solved for a long time. The mechanism of the carling forming and spring back is analyzed. The carling forming and spring back processes are simulated by KMAS software. The warp of carling underside is researched by half analytic and half experiment method and the best scheme is found by this method.
