“…4). The analysis of these values shows that the greatest acceleration is at the points closest to the anvil, which is also in line with the experimental data and is one of the elements of model validation [1], [6].…”

“…In the bolt joints friction was taken into account -accepted coefficient of friction µ = 0.4 -according to the idea of stressed or rivet joints, where the load capacity of the joint is obtained by the effect of friction induced by compression, and not by shearing and pressure as in conventional joints. Validation of models was based on the measurement data obtained on the test bench, as in earlier works of the co-authors [1], [6].…”

“…This article presents an analysis of the load capacity of the bolt joints of collecting electrodes with the rapper rod, made in HUCK technology. In the structure tested, the collecting electrodes of an electrostatic precipitator are periodically cleaned by inducing violent vibrations in them -the acceleration values definitely exceed 1000 ms -2 (1). These vibrations are caused by the impulse forces of drop-weight hammer impacts in the anvils of rapper rods [2].…”

This article presents an analysis of the load capacity of the bolt joints of collecting electrodes with the rapper rod, made in HUCK technology. A discrete model of the system of electrodes was worked out for the analysis of stresses in bolt joints, the validation of which was made on the basis of measurement data obtained on the test bench. Two variants of joining the plates of electrodes with the rapper rod were taken into account in calculations -the first one with the correct geometry in the rapper rod, the other one with an eccentric displacement of holes in the flat bars of the rapper rod. In both variants the modelled system was loaded with the impulse force corresponding to the impact of the hammer against the anvil, with the run obtained from measurements on the test bench. These models and the related calculations were performed in the ABAQUS environment. As a result of the analyses performed, recommendations were worked out intended to eliminate cases of the destruction of bolt joints closest to the anvil of the rapper rod.

“…W artykule przedstawiono analizę naprężeń w połączeniach sworzniowych elektrod zbiorczych z drągiem strzepującym, wykonanych w technologii HUCK  . W badanej konstrukcji elektrody zbiorcze elektrofiltru suchego są okresowo oczyszczane przez wzbudzanie w nich gwałtownych drgań -wartości przyspieszeń w sąsiedztwie drąga strzepującego zdecydowanie przekraczają 1000 ms -2 [1]. Drgania te są wywoływane siłami impulsowymi uderzeń młotków opadowych w kowadła drągów strzepujących [2].…”

Streszczenie: Artykuł przedstawia analizę naprężeń w połączeniach sworzniowych elektrod zbiorczych z drągiem strzepującym. Celem była identyfikacja przyczyn występowania przypadków niszczenia niektórych połączeń znajdujących się najbliżej kowadła drąga strzepującego. W obliczeniach uwzględniono dwa warianty połączeń płyt elektrod z drągiem strzepującym -z poprawną geometrią otworów w drągu strzepującym oraz z mimośrodowym przesunięciem otworów w płaskownikach drąga strzepującego.Słowa kluczowe: nośność połączeń sworzniowych, siła impulsowa, drgania IDENTIFICATION OF CAUSES OF HUCK  TYPE JOINTS FAILURE Summary: This article presents a stress analysis of the bolt joints of collecting electrodes with the rapper rod. The goal was to identify the causes of damage to some of the joints closest to the anvil of the rapper rod. Two variants of the joints were taken into account in calculationswith the correct and incorrect geometry.

“…Therefore electrostatic precipitators are one of the most commonly employed particulate control devices for collecting particulate emissions from boilers, incinerators and from many other industrial processes. Hence, many studies examine performance, operation and improvement of industrial precipitators [13][14][15][16].…”
