摘要
摆动系统是混凝土泵的关键部件,用于实现泵料和吸料的切换。通过分析摆动系统的液压结构和工作原理,建立摆缸缓冲数学模型,分析缓冲腔压力冲击的影响因素。基于AMESim平台建立摆动系统的仿真模型,分析摆动系统的运动特性,得到蓄能器体积、摆缸缓冲结构对摆动性能的影响规律。优化摆动系统的参数,使换向时间由190 ms缩短到160 ms,同时摆动冲击并未明显增加,满足快速摆动的要求。为混凝土泵摆动系统的设计和优化提供了仿真平台和理论依据。
Swing system is the key component of concrete pump,which is used to switch between pumping and suction.By analyzing hydraulic structure and working principle of the swing system,the mathematical model of pendulum cylinder buffer is established.The influencing factors of pressure shock of buffer cavity are analyzed.A simulation model of the swing system is established based on AMESim platform.The operating law of the oscillating system is clarified.The influences of the accumulator volume and the cylinder cushioning structure on the swing performance are discussed.The parameters of the swing system are optimized,and the reversing time is shortened from 190 ms to 160 ms,while the swing impact did not increase significantly,which met the requirements of fast swing.The results provide a simulation platform and theoretical basis for the design and optimization of the concrete pump swing system.
