本文根据快速闸门的实际运用情况，同时结合了高精度南水北调工程水泵模型同台测试试验台上开展的模型泵全特性试验，试验主要包括水泵工况、水泵制动工况和水轮机工况，以一个转轮为对象，做3至5个叶片安放角度的全特性试验。

The interference, which has much to do with shimmy and handling characteristic and directional stability of vehicle, between the suspended structure, the front axle and steering system is described accurately In the models, the concrete component parameters or the design parameters are adopted to make it easy that the models are directly used in optimization design of real products. In order to make mathematical simulation and optimum analysis accurately with a particular vehicle and to study the influence of tyre characteristics on the lateral dynamic performance of vehicle, not only are the whole structure parameters in the models measured, but also is the test of the tyre cornering characteristics done, the accurate parameters of the tyre cornering characteristics are obtained and the practical tyre models of both steady state and dynamic state are selected.

为了提高仿真计算与优化分析的精度，和进一步分析有关轮胎特性对汽车横向动力学特性的影响，除了测量了模型中的全部结构参数外，特别做了轮胎侧偏特性试验，获得了比较准确的轮胎特性参数，并选用了比较实用的轮胎动态和稳态侧偏特性模型。

After the effects of the mainly nonlinear parameters are analyzed, a position/force hybrid control model is presented for the robot hand with the steel cable as a joint driven unit. The position and speed of robot hand can be controlled by DC motor, therefore, it, how to control grasp force, becomes the key of this thesis.
