摘　　要：由于塔式起重机的结构特性,其容易受到外力如风力的影响。本文提出在塔式起重机上加入半主动液压减振器(ASHD),在不改变塔式起重机主要结构前提下,提高塔式起重机的安全和稳定性。并通过建立数值分析模型进行验证,证明了半主动液压减振器在塔式起重机应用中出色的能量耗散能力从而具有极强的减振效果。Because of the structural characteristics of the tower crane, it is easy to affect by the external force such as the wind and earthquake. In this article, the Accumulated Semi-Active Hydraulic Damper （ASHD） is added to the tower crane, without changing the main structure of the tower crane, to improve the safety and the stability. This research establishes the mathematical analysis model to prove its energy dissipation capability and shock absorption based on the hysteresis loop of ASHD.
