本文主要论述运材汽车列车上的原条捆在运输过程中的振动问题,并把该原条捆视为具有质量和刚度沿原条捆长度方向变化的变截面承载梁,从而建立了动力学模型及计算式,在理论计算中具有足够的精确度。
This paper mainly discusses the vibration problem of the original bale on the freight train during transport and regards the original bale as a variable cross-section carrier beam with mass and stiffness varying along the length of the original bale so as to establish a dynamic Models and calculations have sufficient accuracy in theoretical calculations.
