摘要
以相对振幅矢量和相对振幅矢量和为基础,对CODAD推进系统在不同排间发火间隔角情况下的激励力矩变化进行了研究。结合某船CODAD推进系统实例,对各种发火状态和运行工况下的相对振幅矢量和进行了研究,得出了不同V型夹角情况下扭振激励的主要差异。
Based on vector of relative amplitude and sum vector of relative amplitude, CODAD propulsion system＇s excitation torque under different V firing angle was studied. An example of CODAD system was calculated to study the sum vector of relative amplitude under various firing conditions and working conditions. Finally, the difference of torsional excitation under different V firing angle was obtained.
