The influence of the excursion of the mass center of the torsional vibrating system of the three-string pendulum on the measurement of the moment of inertia is analyzed. A criterion for the mass center of the torsional vibrating system to be in alignment with the central axis of the three-string pendulum and a practical method to measure the moment of inertia of a body about a noncentral axis of mass using the three-string pendulum are proposed.

From the process point of view of the carton box design optimization normally includes the following aspects: first, the material on the carton with process improvement, selection of appropriate materials to production, focused "" five to three; the other is in the efficiency of the process and equipment to learn about existing equipment maximum productivity, production quality of the product, so that different box with the appropriate processes and equipment to produce; third, the design process of process improvement, strengthening the designers and technology staff communication so that the design of the product to be able to give full play to the advantages of enterprise resources; the fourth is to strengthen the carton design-time costs, such as from corrugrted, triangulateration paerboard, and so on through the finishing processes, mainly of the paste, cut shape processed into packaging, and sheathed, and so on, instead of EPS foam, and the use of adhesive paper box instead of nails made of cardboard, prevent moisture transport environment of a nail the appearance of secable and tocommandthe.

从工艺角度优化纸箱箱型安排凡是包含一下几个方背：一是差纸箱配材工艺鼎陈，采取不合的质料来出不销，轻点突不入&五改不一&的收益；二是工艺历程和摆撤的鼎陈，不懂现有摆撤的最不小的出不销本领、出不销不销物的度度境况，使差别的箱型用不合的历程和摆撤来出不销；不一是安排工序的工艺鼎陈，放松安排职员和工艺职员的相同，使安排的不销物没干系充脚阐发企业的资源劣势；第四点不离是放松纸箱安排时不败本的筹算，比如拔取宝瓦楞纸板、边角纸板等通功后道加工工序主给为剥离、焊接不败型等加工不败包拆座、衬垫、护套等，替代EPS泡沫，还有搁置粘合纸箱代庖铁钉纸箱，避免输送洋湿润的境况造不败铁钉生锈带来的表背和搁置上的感化。

A direct yaw moment control controlling vehicle motion by a yaw moment which is actively generated by transversally distributed tire longitudinal forces is becoming one of the most promising means of chassis control for the improvement of vehicle active safety.

通过控制左右车轮上的驱动力和制动力，产生横摆力矩来控制汽车的横摆运动的直接横摆力矩控制技术，可以有效地提高汽车的操纵稳定性。

On the basis of the modification theory, relative modification concept of cycloidal gear pair and the appraisal index of the initial backlash are built to solve the problem that cycloidal gear works unsmoothly in pin wheel of the full-hydrostatic steering control units. The major goal of modification is a uniformity of initial backlash, so equidistance modification that has good effect on improving quality of fluid cycloidal pair is chosen.

为解决全液压转向器转子转动不灵活的问题，在分析现有摆线针轮啮合副齿廓修形理论基础上，建立摆线副修形的相对性概念和间隙分布评价指标，提出无系杆摆线副修形的主要目标应使初始间隙分布均匀，选择的修形方式为等距修形。

Meanwhile, the processing technique of the titanium alloy balance wheel was analyzed, and the machining process was designed too.

The traditional pin-cycloid planetary drive has a series of essential advantages such as small volume, light weight, wide range of speed ratio, high efficiency, and quiet operating as well. On the other hand, it has a natural weak point that the tumbler bearing, which supports the cycloidal gear on the arm is placed inside the cycloidal gear, therefore the size of the bearing is restricted due to the geometry of the gear.

摆线针轮行星传动具有体积小，重量轻，传动比范围大，传动效率高，传动平稳且可靠等一系列优点，但它也有一薄弱环节，即转臂轴承处于摆线轮上输出机构的内部，径向尺寸受到限制，从而限制了摆线针轮行星传动更充分地发挥其承载能力。
