摘要
针对舰船管道的抗冲减振优化问题,讨论了有限元分析软件ANSYS的优化设计分析过程及实现方法.以单个梁模型为基础,模拟了不同的边界条件、不同的管支吊架个数、不同的约束方向上管道的冲击响应.并以简化的右舷柴油发电机组排气管模型为基础建立一个简化的梁模型,提供了一种适用于复杂管道的分析和优化方法,分析了在冲击载荷和正弦载荷以及固定约束下模型的冲击响应,以及在满足冲击响应得到明显改善的最小位移的情况下管支吊架位置的优化.通过本文提出的优化分析方法得到各种约束和吊架数目情况下较理想的管夹吊架位置,使在同样的冲击载荷下,管道的冲击响应和变形程度得到较大的改善.
In this paper,ship pipeline vibration reduction optimization was studied.An optimization process and analysis method based on ANSYS was studied.Based on the single beam model,the response of the shockwave of the pipes was simulated with various boundary conditions,different numbers of pipe clamps,and several directions of the constraint.A reduced beam model was established based on the reduced model of the starboard diesel generator＇s vent-pipes.An analysis and optimization method was provided for complex pipes.Considering different numbers of the pipe clamps,the model＇s response to a shock wave was analyzed in the case of shock load,sine load,and a fixed constraint.The position of the pipe clamps was optimized for the minimum displacement when the shock response was obviously improved.The best position of the pipe clamps was obtained from thorough analysis.The response and displacement were improved due to the same shockwave.
