摘    要:建立了林用起重机木捆偏摆系统的动力学模型,并经过线性简化得出木捆在垂直方向的摆角主要与其同向的小车加(减)速度和绳长,以及木捆升降速度有关,而水平摆角与自身的转动惯量和钢丝绳的扭转系数有关.建立了小车制动后木捆匀速下降过程的二自由度木捆摆振微分方程,最后采用Simulink对振动微分方程进行仿真,结果表明绳索长度、木捆...

关 键 词:林用起重机  木捆偏摆系统  动力学模型  仿真

Abstract:A study was conducted to establish a dynamic model of log bundle deflection system for gantry crane in forestry.Relationships between swing angle of log bundle in the vertical direction and trolley's acceleration,rope length and lifting speed of log bundle are obtained by linear simplification,while the horizontal swing angle is related with the torsion coefficient of wire rope and its inertia.Load shimmy differential equations of uniform descent of log bundle after the trolley brake are set up.Moreover,vib...
Keywords:Crane in forestry  Log bundle deflection system  Dynamic models  Simulation
