纵骨交错布置的巨型总段对接工艺仿真与优化
|
摘要
纵骨交错布置的巨型总段对接工艺过程复杂、需要考虑的问题较多,若在施工现场出现工艺不可行、工装设计不合理等问题,调整工作庞大,严重影响造船周期,研究了巨型总段对接工艺仿真与优化方法。建立移位对接工艺仿真模型并进行工艺过程仿真;建立碰撞检测模型和虚拟人模型对仿真过程进行实时检测;基于船体实测数据,提出顶起量自动计算和外板对接偏差调整方法对移位对接工艺进行优化。基于上述方法开发了原型系统,并通过实例证明了本方法的有效性。
The process of giant block erection of longitudinal staggered arrangement is complicated.If the design of process and tooling are not reasonable,the adjustment work in the construction site,which affects the shipbuilding cycle seriously,will be abundant.To solve these problems,the method of process simulation and optimization on giant block erection were researched.Simulation models were established for carrying out the process simulation,and the simulation process was detected in real time by establishing collision detection model and virtual human model.Based on the measured data of the ship hull,the automatic calculation method of raising height and the deviation adjustment scheme of side plates were presented to optimize the process.Prototype system was developed based on the method above,and the effectiveness of this method was proved by an example.
