Strength of hydrostation trash rack bars
Trash racks are one of the important parts of the mechanical equipment of hydroelectric stations since their breakage causes shutdown of the turbines until they are repaired. Therefore, the provision of trouble-free operation of racks is of importance. The author states that the most vulnerable part of the rack structure is the bars, which can be damaged both from the static load as a result of clogging and from the stresses occurring during vibration of the bars under the effect of the water passing through them. Used for explaining the processes in the case reported here is the Milovich theory, which does not however touch on all the causes and conditions of increase of oscillation amplitude as it is observed in the laboratory.
