Trunova I. Technical facilities development of external straightening of car body panels

The thesis is dedicated to the creation of technical facilities of the external straightening which make it possible to improve the efficiency of car body straightening. For the first time, in the paper regularities have been determined which specify creation conditions of technical facilities for the external magnetic-pulse straightening of car body panels, whose structural components are matching devises. Course regularities of electrodynamic processes in external straightening of car bodies have been defined, as well as methods of electromagnetic process research in separate and combined matching constructions of technical facilities of magnetic-pulse force action have received further development. In the thesis the mode of upgrading of straightening efficiency by means of application of technical facilities - tools of external electromagnetic action is proposed. Functional possibilities of tools of the magnetic-pulse straightening method have been determined. Technical facilities for external straightening of car body panels have been developed, resolutions on structural construction of really working tools have been stated and justified, their capacity for work has been justified theoretically and experimentally. The experimental approbation of developed constructions of technical facilities of magnetic-pulse force action has been carried out as the result of it effective elimination of dents on real models of car body panels have been performed.
