CompAct-VSA Design and modelling
本文介绍了一种新型变刚度执行机构(CompAct-VSA)的设计与建模。压实- vsa的工作原理是基于具有连续调节枢轴点的杠杆臂机构。提出的概念允许开发具有大刚度范围和快速刚度调节响应的驱动单元。执行机构的实现利用凸轮形杠杆臂与可变枢轴驱动齿条和小齿轮传动系统。这种实现导致了高度集成和模块化的组装。尺寸和重量确实是VSAs设计中的一个开放问题，这最终限制了它们在多自由度机器人系统中的实现。本文介绍了执行机构的原理、工作原理和模型。初步结果表明，所提出的压实vsa设计具有快速的刚度调节响应和较大的刚度范围。(This paper describes the design and modelling of a new variable stiffness actuator (CompAct-VSA). The principle of operation of CompAct-VSA is based on a lever arm mechanism with a continuously regulated pivot point. The proposed concept allows for the development of an actuation unit with a wide range of stiffness and a fast stiffness regulation response. The implementation of the actuator makes use of a cam shaped lever arm with a variable pivot axis actuated by a rack and pinion transmission system. This realization results in a highly integrated and modular assembly. Size and weight are indeed an open issue in the VSAs design, which ultimately limit their implementation in multi-dof robotic systems. The paper introduces the mechanics, the principle of operation and the model of the actuator. Preliminary results are presented to demonstrate the fast stiffness regulation response and the wide range of stiffness achieved by the proposed CompActVSA design.)

NURBS110707
高速切削加工技术是一种先进的制造技术，具有强大的生命力和广阔的应
用前景，已成为切削加工的主流。数控插补技术是数控系统实现轨迹运动控制
的基础，插补运算是CNC系统软件实现运动控制的核心模块，插补算法的优劣
将直接影响到CNC系统的性能。因此，实现一种高精度和高速度的插补方法是
插补的关键所在。
本文在分析传统基准脉冲插补、数据采样插补的算法的基础上，着重研究
了三次NURBS曲线实时插补技术，针对部分算法的不完整或效率低，提出了
一种简单快捷的插补算法。采用NURBS曲线的矩阵表达式，将整个插补过程
分解为插补预处理和实时插补。在插补预处理中完成了大量的计算，预处理的
计算结果直接应用于实时插补，使插补算法满足了NURBS曲线插补的实时性
要求，再辅以必要的轮廓误差控制，实现了加工速度自适应于加工路径的
NURBS曲线直接插补。
本文讨论的插补算法采用C++语言实现，并在VC++6.0的编程环境中实现
了插补算法的计算机仿真，验证了算法的正确性和可行性。(The high speed cutting is one of advanced manufacture technique,which has the powerful vitality and the broad application,and already became the mainstream of machining.The interpolation technology of NC is the foundation of path s control in the CNC system,and the interpolation operation is the core module of
CNC system software,which comes the motion control true.The interpolation
algorithm,whose function is good or bad,directly influences the performance of CNC system.So,a kind of interpolation method with the high accuracy and high speed is the key of interpolation.
Based on analyzing the traditional pulse interpolation and data sampling
interpolation,this paper emphasizes on the NURBS curve real-time interpolation
technology.In view of the partial algorithms which is incomplete and the low efficiency,this paper propose a simple and quick interpolation algorithm.Using the
matrix representation of NURBS curve,the whole interpolation process is divided into appropriate pretreat)

有限元计算程序(matlab)
它将求解域看成是由许多称为有限元的小的互连子域组成，对每一单元假定一个合适的（较简单的）近似解，然后推导求解这个域总的满足条件（如结构的平衡条件），从而得到问题的解。(It regards the solution domain as consisting of many small interconnected subdomains called finite element elements, assumes a suitable (relatively simple) approximate solution for each element, and then deduces that the solution of this domain satisfies the conditions (such as the structural equilibrium condition), so as to obtain the solution of the problem.)
