摘要
自行式液压平板车(Self-propelled modular transporter,SPMT)主要应用于重型和超大型结构物的运输,在港口码头大件滚装、装备制造业、海洋石油、化工、桥梁建造等工程领域应用广泛。由于货物荷载大,SPMT的车板常常发生较大挠曲变形,且变形随货物、支墩位置变化而变化。工程技术人员需要综合考虑SPMT的支撑原理及升降调节能力,这涉及复杂的力学计算,且计算过程复杂,效率不高。依靠施工经验完成操作,具有较大的主观性。本文利用有限元设计方法,辅助用户设计并优化布车位置及运输支撑位置,达到减少SPMT受力及变形情况,降低施工风险的目的。
SPMT(Self-propelled modular transporter)is mainly used for transport of heavy and super-large structures,which is widely applied in roll-on in wharf,equipment manufacturing,offshore oil,chemical engineering and bridge construction etc.The large load from the cargo often causes large deflection deformation of the SPMT floor,which changes with the position of the cargo and the position of the bearing beams.Engineers need to comprehensively consider the support principle and adjustment of SPMT,which involves complex mechanical calculation,thus the calculation process is complex and inefficient.Relying on experience to complete the operation has the disadvantage of greater subjectivity as well.In this paper,the finite element design method is introduced to assist the user to design and optimize the position of vehicle and transportation support,so as to reduce the stress and deformation of SPMT and reduce the construction risk.
