侧推力 [力] side thrust
- 分析了零航速时侧推器推力、功率与船体回转角速度的关系;
After analysing the phenomena of thrust reduction at ship speed, the author proposes two methods for countering such phenomena. - 钢丝绳向新的一层过渡时,对端侧板产生轴向推力,导致侧板弯曲,同时在侧板与筒壁过渡处产生较大应力。
The axial force toward the side board is always produced when the wire rope reaches the new layer. It makes the side board bended and causes very large stress between the side board and the roller. - 在分析互馈双电机推力平衡关系的基础上,提出基于矢量控制的互馈双电机联合控制策略,研究牵引电机侧速度调节和负载侧推力模拟的方法。
Simulation and test results show that the LIM reciprocal power-fed test system using the above associated control strategy has good steady-state performance, and good speed and load force adjustment.
