理论上,压力容器优化设计变量可以取任意实数值,但从制造工艺的角度却很难保证,导致势必对优化结果进行圆整而引起解的质量的恶化,直接对离散变量优化模型进行求解可以避免此类问题。LINGO优化软件内置建模语言,提供几十个内部函数,能用简洁的语句表示并快速求解离散的和连续的优化模型。用LINGO对一压力容器进行优化设计使其壳体的耗材体积减少了约7%,表明LINGO应用于压力容器的优化设计是可行的。
In theory, pressure vessel optimization design variables can take any real value, but from the manufacturing process point of view is difficult to guarantee, resulting in the optimization of the results will inevitably lead to the deterioration of the quality of the solution directly to the discrete variable optimization model can be solved Avoid such problems. LINGO optimization software built-in modeling language, providing dozens of internal functions, can be expressed in simple sentences and quickly solve discrete and continuous optimization model. The optimized design of a pressure vessel with LINGO reduced the consumables volume of the shell by about 7%, which shows that it is feasible to apply LINGO to the optimization design of pressure vessel.
