In the sense of Von Karman large displacement, the governing equation of nonlinear dynamic response of the clamped circular plates under impact of a mass is established by using the virtual displacement principle and Galerkin's method in this paper. The effect of coupling between the impact load and the displacement of. the circular plates is considered. The governing equation is solved by applying the time increment method and the singular perturbation theory, and the asymptotic solutions of nonlinear dyna...

Furthermore, the performance of half right circular corner filleted flexure hinge was analyzed, including the effect of its geometric parameters on its performance. Compared with symmetrical right circular corner filleted flexure hinge, the compliance and sensitivity to the load of half right circular corner filleted flexure hinge were better than those of symmetric right circular corner filleted flexure hinge. The above results provide a new idea for the applications of flexure hinge, which is used in compact structure and structure with large displacement.

同时对单边直圆导角复合柔性铰链的性能进行分析，分析了结构参数对其柔度性能的影响，通过与双边直圆导角复合柔性铰链比较，得出了单边直圆导角复合柔性铰链的转动能力、对载荷的敏感性均优于双边直圆导角复合柔性铰链，为柔性铰链在结构紧凑、大位移场合的工程应用提供了新的思路。

The roundness tester is a highly precision instrument that is wildly used to measure the rotary work piece in mechanical industry. The aged roundness tester was astricted by the technique condition of that time, so its way of measurement is not at all advanced. Because these roundness testers have been used for a long time, they have a highly failure rate and their accuracy can not be insured.

圆度仪是机械工业中应用最广泛的检测回转体零件圆度误差的高精度仪器，由于老式的圆度仪受当时技术条件的限制，评定方法落后，再加上这些圆度仪的使用时间较长，使用时仪器的故障率一般都较高，测量精度也不能保证。

That is, the business card printing and membership card making thousands of pieces of paper, in particular domestic uncoated paper or book paper occurs paper wool, paper powder in the rubber roller, imprinted on the edge of the paper and paper Mao superdirective (direction to bite or to drag-and-shoot direction), the not equal to the linear speed of the roller, only in the cylinder lining after business card printing and membership card when, in the rubber roller paper coated maoba non-directional well, then this data is only lining is the best, that is, until you reach the drum running as business card printing and membership card making ink plates and blankets, as well as on the status of the delivery is the best.

即制卡和会员卡制作几千张纸(出格是舶来胶版纸或书刊纸)后不离会不入现纸毛、纸粉粘在橡皮滚筒上，若痕迹边际的纸粉、纸毛有不圆向性(向咬口不圆向或向拖梢不圆向)，则表明不有到达滚筒线速度不不等，只有在滚筒包衬后制卡和会员卡制作时，在橡皮滚筒上纸粉纸毛堆得不有有不圆向性，那么这栽包衬数据才是最恶的，亦即滚筒调动到了运转最恶环境，制卡和会员卡制作历程洋油不朱在印版、橡皮布以及纸张上的传达是最恶的环境。
