水面舰船结构力学性能虚拟测试初步研究

Preliminary Studies on the Structure Mechanics Performance Virtual Test for Surface Ship

在建立虚拟仿真环境库和动态环境库的基础上,实现海浪中航行的船体结构强度、船体自由振动、船体结构疲劳寿命、船体结构总纵强度、总刚度及局部强度等的虚拟测试。以某型舰船的船体结构数据为例进行测试,其结果与强度计算结果基本一致,测试应力均达到许用应力的要求。

The virtual tests were preliminary completed of hull structure strength,structure free vibration,hull structure fatigue life,longitudinal strength,total stiffness and local strength on the basis of establishment of virtual simulation environment and dynamic environment database.The experimental results of a certain ship agreed with the numerical results basically,and the stress results of virtual test were lower than the allowable stress.
