以深海沉积物气密采样器翻板密封阀为研究对象，采用响应面法（RSM）和有限元分析方法，对翻板密封阀的几何设计参数进行优化设计研究。首先，针对海洋深层沉积物气密取样器的加压密封要求，设计了一套偏心设置的瓣式密封阀，利用Solidworks建立了瓣式密封阀的三维几何模型，以瓣式密封阀偏心角θ、阀盖上端直径D3、阀盖长度lthe.design变量，以阀体下端开口直径D5和给定安全系数下的材料强度set.as，以阀瓣密封阀的最大应力值和重量为优化目标，建立了阀瓣密封阀偏心角θ、阀盖上端直径D3、阀盖长度l和阀瓣密封阀最大应力和重量的响应面模型。最后，对翻板密封阀的几何结构、参数进行了优化设计
Taking the deep sea sediments air-tight sampler flap seal valve as the.research object, using the response surface method (RSM) and finite.element analysis method to carry out the flap sealing valve geometry design parameter optimization design research. First of all, a set.of eccentrically set flap seal valve is designed for the requirement of.the pressurized seal of the marine deep sediment air-tight sampler,.three-dimensional geometric model of the flap seal valve is built using Solidworks.Then, The flap sealing valve eccentricity angle θ, the.valve cap upper end diameter D3, and the valve cover length l as the.design variables, the bottom end opening diameter D5 of the valve.body and the material strength under a given safety factor are set.as constraints, the maximum stress value and weight of the flap seal.valve are set as optimization goals.The response surface model of the.flap sealing valve eccentricity angle θ, the valve cap upper end diameter D3, the valve cover length l and the flap sealing valve maximum.stress and weight is constructed. Finally, The geometrical structure.parameters of the flap sealing valve are optimized
