摘要: 在直升机肋管式滑油换热器的初步热力性能设计计算基础上,应用数值优化原理,对滑油换热器结构的优化设计进行了研究,建立了结构优化程序.该程序以滑油换热器的重量为目标函数,采用正弦法去约束并结合单纯形加速法寻优.实例计算表明,将滑油换热器的热力性能计算程序同结构优化程序结合起来,可以建立自动匹配的换热器设计及优化程序系统.应用该软件,输入设计要求,就可获得既满足性能要求,且重量最轻的肋管式滑油换热器.该软件可推广应用于各种类型肋管式换热器.

Abstract: Basing on numerical optimization principles and thermodynamic performance design, efforts were made to optimize the design of finned-tube lubricate heat exchangers used in helicopters. By taking the weight of the lubricate heat exchangers as an objective function, using the sine method to deal with design constrains, and selecting the simplex accelerated method to search optimization results, optimization design program was developed for the exchangers. An example was given to show that optimum design requirements can be realized by coupling the structure optimization program with the thermodynamic performance design program.
