Abstract

The non-linear bend of flight of the horizontal pipeline on two support under the influence of impact pressure in internal liquid with taking note of longitudinal force on a bend is considered. The solution of the non-linear equation of the task is received by the numerical method. Comparing of results is given in the linear and non-linear settings. It is shown that in a non-linear case there is an oscillatory mode of movement of the pipeline, in difference from the linear case when there is an exponential growth of amplitude of a bending of the pipeline.
