混合主动-被动阻尼处理联合收割机结合了粘弹性阻尼处理的可靠性、低成本和鲁棒性以及高性能、模态选择和自适应压电主动控制。在文献中已经报道了许多混合阻尼处理。它们的区别主要在于粘弹性处理、传感器和压电致动器的相对位置。在这项工作中，我们提出了三个主动-被动阻尼设计配置应用于悬臂梁的实验分析。特别是，两个设计配置的基础上的延伸模式的压电致动器结合粘弹性约束层阻尼处理和一个设计配置剪切压电致动器嵌入夹层梁与粘弹性核心进行了分析。为了比较的目的，一个纯粹的主动设计配置的延伸压电致动器粘接到弹性梁进行了分析。比较了四种设计结构的主被动阻尼性能。结果表明，主动-被动设计结构比纯主动结构提供更可靠和更宽范围的阻尼性能。
Hybrid active—passive damping treatments combine the reliability, low cost and robustness of viscoelastic damping treatments and the high-performance, modal selective and adaptive piezoelectric active control. Numerous hybrid damping treatments have been reported in the literature. They differ mainly by the relative positions of viscoelastic treatments, sensors and piezoelectric actuators. In this work we present an experimental analysis of three active—passive damping design configurations applied to a cantilever beam. In particular, two design configurations based on the extension mode of piezoelectric actuators combined with viscoelastic constrained layer damping treatments and one design configuration with shear piezoelectric actuators embedded in a sandwich beam with viscoelastic core are analyzed. For comparison purposes, a purely active design configuration with an extension piezoelectric actuator bonded to an elastic beam is also analyzed. The active—passive damping performance of the four design configurations is compared. Results show that active—passive design configurations provide more reliable and wider-range damping performance than the purely active configuration.
