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。 Due to the structural characteristics of the tower crane, it is susceptible to external forces such as wind. This paper proposes to add semi-active hydraulic shock absorber (ASHD) to the tower crane to improve the safety and stability of the tower crane without changing the main structure of the tower crane. The numerical analysis model was used to verify the performance of the semi-active hydraulic shock absorber in tower crane crane. The results show that the semi-active hydraulic shock absorber has excellent energy dissipation capability and thus has a strong damping effect.
