ABSTRACT In this dissertation, fault-tolerance of redundant manipulators is thoroughly investigated. First, inherent relationship between the dexterity and fault-tolerance of single-redundancy manipulator is discussed. Both the manipulability and the relative manipulability are utilized for measuring the kinematic fault-tolerance of the manipulator with one joint failure. Furthermore, the relative manipulability is used for measuring dexterity loss resulted by one joint failure, and the relationship between the fault-tolerance measurement and null space vector of Jacobian matrix is established.

本文对冗余自由度机器人的答错性问题进行了深入的分析和迭付：首先研究了单冗余度机器人运动学灵活性与容错性之间的内在关系，提出以故障构形的可操作度和相对可操作度来度量机器人的运动学容错性，用相对可操作度来度量关节故障给机器人操作灵巧性造成的损失，并建立了容错性度量指标与Jacobian矩阵零空间向量之间的关系。

Furthermore, open of segment joints, stretch of connected bolts and contact stress distribution on joint faces are the main points which decide whether or not the joint is safe.

同时，接缝的张开、连接螺栓以及接缝处接头面的受力状态是判断接头是否安全的主要依据。

A plane joint model was built in this thesis. By using it, not only M-θ curve of joints but also open of segment joints, stretch of connected bolts and contact stress distribution on joint faces can be obtained.

为此，本文建立了平面型纵缝接头的力学模型，根据该模型除能得到衬砌二维计算所需的接头M-θ曲线外，还能分析接头面的受力状态并得到接缝的张开值、螺栓受力。

The four single errors exist in joint B in crank.rocker mechanism. The result indicates that the theory analysis is correct. In order to analyze the distribution of contact stress in joints, the ANSYS finite element tool is used. The situation of four single errors in joint B is analyzed. The distribution of contact stress is actually reflected. The microcosmic stress analysis is referred.

为了分析铰链在存在形位误差的情形下铰链中接触应力的分布情况，利用ANSYS有限元分析工具，通过对B铰链存在的四种可能出现的形位误差造成在装配过程中产生的接触应力的分析，真实的反映了铰链接触应力的分布情况，从而由宏观的力分析进入微观的应力分析，这也是前人没有涉及过的。

The optimum solution is gotten by Joint limitation avoidance, then the joints trajectory can be obtained by interpolation calculation of three order polynomial, finally PTP trajectory in joint coordinate system is planned.
