混凝土泵车臂架抑振技术研究与应用

摘要

混凝土泵车在泵送换向过程中产生液压冲击、混凝土不连续冲击、冲击频率与臂架固有频率区接近,使得末节臂架在垂直方向抖动达1米以上,直接影响了臂架的寿命及操作人员的人身安全,同时泵车臂架是一个大惯性、大延迟、非线性系统,传统控制方法很难奏效,全球主要泵车制造厂家均不遗余力地进行减振研究.本文概述了国内外一些厂家在被动减振控制、主动减振控制的研究成果与进展,并对臂架振动抑制控制技术进行了展望.%Due that the truck mounted concrete pump produces hydraulic and concrete impacts on pump exchanging,the upright amplitude of bottom boom,which exceeds one meter,affect the handler life and safety.Subsequently,such manufacturers as SANY attempt efforts on vibration suppression,whereas active control and passive controls on vibration are reviewed.Consequently,the technological advances of vibration suppression are presented for truck mounted concrete pump booms.
