A numerical method of analysis for the inverse kinematics problem of ยฏexible link systems is presented. The proposed method is based upon an iterative scheme, which consists of updating the system conยฎguration stepwise, by correcting the positioning error due to link deformations through rigid body motions of ยฎnite amplitude. The resulting nonlinear compensation scheme reduces to the solution of the inverse and direct kinematics problems of a sequence of equivalent rigid link systems. These solutions are symbolically derived by means of the Groร bner basis method. The convergence analysis of the proposed algorithm is developed. The applicability and the performance of the present method are veriยฎed trough some numerical tests, highlighting its advantages and disadvantages in comparison with other methods found in the literature.

We analyse the vibration eigenfrequencies of a flexible slewing beam with a payload attached at one end. A wave propagation method (WPM) is used. There are four types of waves which propagate along a beam-two dispersive waves travelling in opposite directions, and two evanescent waves near the endpo
