Case Calculation and Analysis of Insufficient Traction Force in Elevator
Abstract For the traction driven elevator, the satisfaction of traction conditions is the basic guarantee for the normal operation of the elevator. If the traction force is insufficient, there will be skid, slip and other phenomena, which not only cannot meet the design requirements of the elevator manufacturers, but also easy to cause ...

Nonintrusive coupling of 3D and 2D laminated composite models based on finite element 3D recovery
In order to simulate the mechanical behavior of large structures assembled from thin composite panels, we propose a coupling technique which substitutes local 3D models for the global plate model in the critical zones where plate modeling is inadequate ...

When calculating short-circuit currents in the AC traction network, it is assumed that each of the traction substations receives power from uncoupled external power supply sources with known resistances. In some cases, especially when powering a group of traction substations from a high-voltage power line of a longitudinal power supply, the external ...

GRADE COMPULATIONS ON PARET’S SET WITH TWO INDEXES
The problem of train traction calculations is considered as the one of resource allocation in a vector formulation. The solution is based on dynamic programming using a set of points of the optimal Pareto objective function values (energy, time).
