开发了一个交互式计算机程序，用于设计飞机发动机隔振悬置系统。安装设计主要由两个相互竞争的标准驱动。支架必须足够柔软以提供振动隔离，但必须足够坚硬以支撑发动机而不会过度运动。约束变尺度优化技术被用来确定安装的设计参数，最大限度地减少在安装的传输力，受到约束的最大允许偏转的发动机的静态力。设计参数是每个单独发动机悬置的刚度和方向。飞机发动机被建模为一个刚体，安装到一个刚性的基础代表机舱。实例表明，该优化方法在发动机悬置系统设计中是有效的。
An interactive computer program has been developed to design aircraft engine mounting systems used for vibration isolation. Mount design is largely driven by two competing criteria. Mounts must be soft enough to provide vibration isolation, yet stiff enough to support the engine without excessive motions. The constrained variable metric optimization technique is used to determine the mount design parameters which minimize the transmitted forces in the mounts, subject to constraints on the maximum allowable deflection of the engine to static forces. The design parameters are the stiffness and orientation of each individual engine mount. The aircraft engine is modeled as a rigid body that is mounted to a rigid base representing the nacelle. An example is used to show that the optimization technique is effective in designing engine mounting system.
