| The nonlinear mathematical model of fuel fluctuations in the pipeline with a nonlinear gas-liquid damper is offered. The gas-liquid damper is the concentrated elastic element with small rigidity. On the basis of the received model nonlinear fluctuations of system are investigated. The offered technique will allow specify calculations of liquid fluctuations in pipeline with a gas-liquid damper. |
