“…In order to increase the power transferred by drives, i.e. to increase the torque being transferred maintaining unaltered rotational speed, one can use higher quality materials [9][10][11][12][13][14][15][16][17][18] or specific technological procedures [9,[19][20][21][22][23][24]. All these means are commonly applied in manufacturing of harmonic drives.…”

The author of the article applied the boundary element method (BEM) to determine stresses occurring in a toothed rim of a flexspline. The relevant numerical calculations were conducted using software developed at the Faculty of Transport of the Silesian University of Technology. The numerical analysis conducted for flexsplines entailed the impact exerted by parameters of an indented toothed flexspline rim (number of teeth, addendum modification coefficient) and of a gear tool (gear tool head curve radius, pressure angle) on values of the stresses occurring at the tooth space bottom. Results of the said calculations have been depicted as curves of dependences between stresses at the tooth space bottom in the function of the number of flexspline rim teeth on constant values of the addendum modification coefficient. The cumulative diagrams developed based on the results of the calculations conducted may provide guidelines as to the manner of designing flexsplines for harmonic drives.

The current trend of weight reduction entails a reduction in safety factors. This approach is understandable, but light profiles are more susceptible. The structure works close to the boundary loads, and their destruction is primarily determined by dynamic relief. Today, composite masts are diagnosed by the following methods: optical microscopy, electron microscopy, X-ray analysis and thermal analysis. These methods are invasive methods. It seems that the vibration analysis of the mast-rigging system could supplement or replace the mentioned methods without the need to dismantle the mast, giving the possibility of testing on the yacht [5]. The article presents the possibility of diagnosing a composite material defect on the example of a interrupts a continuity of structure.

“…Because of the lack of dynamic computation methods, Authors in some previous works [1][2][3][4][5] proposed methodology of building mathematical model based on some experimental results. The results obtained in these works made it possible to develop the accurate model of the shaft, that simulates critical acceleration and deceleration.…”

Abstract. Carbon fiber drive shafts are nonlinear structures of complex character, difficult to establish "a'priori". The only way of modeling is to make identification based on the results of measurements of real objects. In previous works, Authors describe the process of building a mathematical model of such a system and its identification on the basis of experimental results but for only one reduced mass. On this basis, however, it is not possible to write a two-mass model because the identified function describing the resilience characteristics also 'covers' errors of other model parameters. So, Authors in this paper showed the process of selection of right model which can show the effects of passing shaft's critical speeds by system with two reduced masses.In conclusion, future model identification procedure for nonlinear phenomena was announced.
