On some particularities in the modeling of thermo-bimetal strips


    Abstract: Modeling of thermo-bimetal strips, used in electrical devices, is a complex process requiring implementation of multi-physical models. The latter are based on mathematical apparatus, describing several tasks: thermal, electrical and mechanical.
    This article discusses some particularities in the modeling of thermo-bimetal strips by describing the mechanism of model making. Focus is given to constructions heated indirectly or directly by the current running through them. The purpose of these models is to complement the analytical description of the processes, offered by a number of authors before. The results from the computing procedures thus obtained can be used for analyzing thermo-bimetal strip efficiency as well as for immediate implementation in construction and design practice.


Analysis and modeling of thermo-bimetal strips of a complex shape


    Abstract: Being part of electrical devices: thermal relays, automatic breakers, etc., thermo-bimetal strips deserve careful studies in order to determine their efficiency for a specific engineering design. This article discusses thermo-bimetal constructions of complex shapes: spiral, spherical, U-shaped - all of which make analytical descriptions much more difficult. It is possible to present their modeling by means of digital methods and software products so that the object deformation can be well examined. The computing procedure results in obtaining the value of their movement at the free end. Therefore, this project suggests a possibility for the process of modeling of thermo-bimetal strips to complement and modernize the classical methods of analysis.
