Abstract. Staging studies. Examines the dynamic reaction of hanging carrier pipeline system is not rectilinear forms on the current when an water hammering effects.
The results. Describes the methods and results of its testing to describe non-stationary fluctuations odnoproletnogo hanging water pipeline when an hydraulic impact, focused on the use of modern computing systems. Uses dynamic finite-element computation scheme for estimating maximum efforts in carrying elements of constructions from the actions of shock loads in unsteady operating conditions resulting from the sudden stop of the pump or closing the flaps. The results of theoretical calculations are compared with data obtained in the survey operated hanging odnoproletnogo water pipeline.
Conclusions. Application in engineering practice, the proposed methodology allows you to predict the behavior of the hanging pipe in unsteady operating conditions and avoid accidents. Under conditions of water hammer in pipelines with complex profile raises drums efforts that can greatly exceed the efforts from static loads.
Keywords: hanging pipe; dynamic calculation; hydraulic punch; stress-strain State; efforts; operation strength
