In this paper one column of a telescopic construction of a bell tower is investigated. The hinges at the support of the column and at the connecting joint between the upper and lower columns are modelled with rotational springs. The characteristics of the springs are assumed to be non-linear and the hysteresis property of them is represented with t...

To model the behavior of the dynamical system first one column with semi rigid hinges of nonlinear hysteretic characteristic are modeled and checked how the hinges behave during the dynamical action. The designed form of the bell tower can be seen in Fig. 3. (Fig. 4). Figure 4. The mass two columns system with the external force To model the moment of the electrical motor for forcing the bells to toll a concentrated, horizontal directed, exponentially increased periodically changing force is acting during the tolling process with amplitude F 0 =1000 N ( Fig. 5), of cycling ...

Various kinds of wound roll defects such as telescoping, dishing, starring, and wrinkles often appear in many manufacturing lines of web handling. In order to investigate how the dishing or telescoping is developed and to get fundamental knowledge of these roll defects, several web winding processes are simulated by using a simple three dimensional...
