Modeling Strategy

In this paper, we present a simplified magneto-thermal modeling strategy for switched reluctance electrical machines (SRM) operating at high temperatures. In addition to the magnetic non-linearity, the variations of the electromagnetic and thermal properties of materials with the temperature are taken also into account. The rapidity of the proposed approach makes it compatible with a CAD approach.

Output Characteristics

The analysis of properties of thermosensitive elements used in devices for monitoring the temperature and thermophysical properties of the medium and materials is carried out. Thermal converters made of various materials are considered: metals, semiconductors, oxides. The sensitivity to infrared radiation of the considered elements is analyzed. The range of measured temperatures and the linearity of the output characteristics of the converters are investigated. A conclusion is made about the purposefulness of using one or another type of thermosensitive elements.

Properties Of Materials

During friction under shock conditions, interface is submitted to very strong heat flux. Thus, it may reach a temperature as high as melt temperature of one of the materials constituting the contact. As a consequence, the income and outcome of heat at the interface governs the friction and the contact behavior. This article exposes a model that resolves the non-linear heat equation in the vicinity of the interface. This way, it takes into account the variations of thermal properties of materials constituting the interface. First results indicate that such variations influence the tribological behavior of the contact.
