摘要

针对舱段主动隔振系统中作动器配置优化问题，给出一种优化模型和方法，通过数值计算进行方法验证。文中首先建立了多通道舱段主动隔振系统的动力学模型，然后将作动器配置优化转换为约束0-1非线性规划问题，以系统监测点响应为优化目标函数，作动器启用状态为自变量，最后采用教与学（TLBO）优化算法寻找最优配置。仿真计算结果表明，对于不同的激励，多通道主动隔振系统的最优配置不同，即存在对应给定激励下抑制壳体振动与声辐射的最优配置。

Abstract

An approach is proposed to search the minimum number of actuators for an active vibration isolation platform-cabin shell system. Based on the established dynamic model of the multi-channel active vibration isolation system, the optimal allocation of actuators in this approach is described as a 0-1 nonlinear programming problem, in which the active/silent state of the actuators are independent variables and the objective function is constructed from the system responses. The teaching-learning based optimization algorithm (TLBO) is used to find the optimal actuator allocation. The optimization is carried out to verify the effectiveness of the proposed method, and the numerical results show that the vibration and acoustic radiation of the shell can be suppressed by part of the actuators in a specific excitation.
