船体变形 meaning in English

hull strained

Two types of alignment algorithms on moving base were put forward in this paper , one with angular velocity matching , and another with acceleration matching . the error models and measurement models in consideration of ship flexure and lever - effect were deduced respectively . the alignment methods were verified by simulation
提出了两种动基座传递对准的方法，一种是采用角速率匹配，一种是采用加速度匹配，并分别推导了在考虑船体变形和杆臂效应时传递对推的误差方程和量测方程，通过仿真验证了这两种传递对准方法的正确性。
The element leading to problems could be extremely complicated , for instance , insufficient consideration during the model setup ; certain affecting elements vary with different types of ship , like the ship hull deformation , shaft vibration and reinforcing hardness and so on ; inadequate accuracy control and errors during the construction
导致问题的因素相当复杂，有计算模型的建立过程考虑因素不周；也有一些影响因素的特定性，对于不同的船型而不同，如船体变形，轴系振动，支座刚度等；还有施工过程精度控制不够或施工过程出现错误。
