Возбуждаемые усилия притяжения в симметричной индукционной индукторной системе – универсальном инструменте магнитно-импульсной рихтовки

Abstract

Проведен расчет возбуждаемых усилий притяжения в симметричной индукционной индукторной системе – универсальном инструменте магнитно-импульсной рихтовки. По полученным аналитическим зависимостям проведены численные оценки с построением объёмных эпюр, фазовых и радиальных зависимостей амплитуднопространственного распределения возбуждаемых сил притяжения. Определено, что влияние магнитных свойств экрана и заготовки проявляется в появлении мощных сил магнитного притяжения.

Проведено розрахунок збуджуваних зусиль притягання в симетричній індукційної індукторній системі – універсальному інструменті магнітно-імпульсної рихтування. За отриманими аналітичним залежностям проведені чисельні оцінки з побудовою об'ємних епюр, фазових і радіальних залежностей амплітудно-просторового розподілу збуджуваних сил притягання. Визначено, що вплив магнітних властивостей екрану і заготівки проявляється в появі потужних сил магнітного притягання.

Recently, repair and recovery of vehicle body operations become more and more popular. A special place here is taken by equipment that provides performance of given repair operations. The most interesting are methods for recovery of car body panels that allow the straightening without disassembling of car body panels and damaging of existing protective coating. Now, there are several technologies for repair and recovery of car body panels without their disassembly and dismantling. The most perspective is magnetic-pulse technology of external noncontact straightening. Results. The calculation of excited loads attractions in a symmetrical inductor system in the universal tool of magnetic-pulse straightening is provided. According to the obtained analytical dependence of the numerical evaluation of volumetric construction diagrams, phase and amplitude of the radial dependence of the spatial distribution of the excited efforts of attraction is obtained. The influence of the magnetic properties of the blank screen and manifested in the appearance of powerful magnetic attraction forces is determined. Originality. A new trend of research of magnetic-pulse working of thinwalled metals has been formulated and received further development, which allows to create not only new equipment, but principally new technological processes of external non-contact repair and recovery of vehicle body panels. Scientific basis of electrodynamic and magnetic attraction of thin-walled sheet metals with using the energy of high-power pulsed fields was created for the first time and proved theoretically and experimentally. Scientific and technical solutions in design of effective tools based on single-turn inductor systems of cylindrical geometry for straightening and recovery of car body panels were formulated and proved theoretically, as well as experimentally. Practical value. Using the results of the calculations we can create effective tools for an external magnetic pulse straightening of car body panels.
