The Finite Element Analysis

This paper presents the stress analysis of a second stage turbine disc, subjected to spin rig test. To solve the problem, the finite element analysis of complex geometrical model of the disc/blade segment with much physical nonlinearity such as contact and plasticity was carried out. The adequate mechanical and thermal conditions for the spin rig test were next defined to determine the stress state of the disc/blade segment. High stress zones were found at the regions of the turbine where the first fatigue cracks are expected to appear. The results of this study are useful during the laboratory spin rig test of turbine. The zones of maximum stress indicated in this analysis will be in detail inspected under laboratory crack initiation and crack growth tests of turbine. For better understanding the phenomena occurring in spin rig test of turbine, the test details were also described.

In the article, the electrical and thermal processes in the LED lamp with varied parameters are investigated. Voltage and current measurements on all LEDs of the luminaire are carried out in the nominal operating mode. The power allocated to each LED is determined. The calculation of the LED crystal temperature was carried out using the developed thermal LED model based on the results of the measurements and by using “Multisim” program. It has been established that the temperature of the crystals of individual LEDs in the luminaire differ significantly, which leads to unfavourable thermal conditions for them and an increased likelihood of premature failure.
