“…Then repeat above process until 4 pairs of bolts tightened OK. Finally, the device would revert to the initial state, before that all data had been stored in PLC and sent to the host computer [5]. 5 was the flow chart of PLC software, could be programmed by TIA Portal V13.…”

Abstract.A new tightening machine was designed in this paper, used for automobile differential mechanism. The PLC as the core controller of this device controlled two screwed shafts by Profibus-DP communication and positioning motor through indexing plate.8 bolts would be tightened to the set torque automatically when the start button pressed. HMI equipment through which the status of device and results of tighten could be saw was equipped.

“…Most often, they can occur in two states of loading and deformation. The first one is the assembly state in which the connection may be set up under different assembly patterns [2,32]. Another feature of multi-bolted connections is that they are constructed of many structural components [7,22,27,28].…”

The paper put forward a thesis that modelling dissymmetric non-linear multi-bolted connections as a system is possible. Modelling of the systems composed of four subsystems on the assembly state was presented. These subsystems included: a couple of joined elements (a flange and a support), a contact layer between them, and bolts. The physical model of the system was described considering the tightening of bolts according to a specific sequence. In this model: the flange and the support were built using spatial finite elements, the contact layer was formed as the non-linear Winkler model, and the bolts were replaced with simplified models made of flexible beams. The calculation model which can be applied to determine the changes in bolt forces, as well as in the normal contact pressure between the joined elements during the tightening of the system and at its end, was presented. The results of sample calculations for the selected multi-bolted system were shown.

“…Such characteristics can be represented with good approximation through exponential functions [7][8][9]. Progressive tightening of the bolts in the pre-tensioning process [10][11][12] is equivalent to gradual tightening of the contact layer located between the joined elements. In such a process, roughness of the surface texture of the elements have less and less influence on mechanical properties of the contact joint.…”
