风级对船舶主推进柴油机加速特性的影响
Influence of wind levels on the acceleration characteristics of a marine propulsion engine
摘要
Abstract
To reveal the acceleration characteristics of the propulsion diesel engine of a ship under wind and wave conditions,in this work,a Very Large Crude Carrier intelligent demonstration ship was chosen.The modular meth-od was applied to establish a comprehensive model of a diesel engine,propulsion system,three-degree-of-freedom motions,and wind wave interference.Validation of the model was performed by the engine bench test and ship sea trial test data.By simulating the acceleration process of the diesel engine at different wind levels,the calculated operating limits of the main propulsion diesel engine of the ship at different wind levels revealed the influence of winds and waves on the acceleration performance of the propulsion system,revealing that with increasing wind levels,the power margin of the diesel engine during the acceleration process became smaller and smaller and the limit of continuous safe operation was 57.4 r/min and 18 866 kW,51 r/min and 14 910 kW,and 48 r/min and 13 560 kW at wind levels of 8,9,and 10,respectively.The wind level primarily influences the compressor effi-ciency during the acceleration process,having little impact on the safety of superchargers.This work can be em-ployed to provide guidance on the design of ships for navigational safety.关键词
