摘要
对已经建立的弦线振动动力学方程中各项进行量纲分析,确定各项关于基本物理量长度L、质量M、时间T的因次,对动力学方程两端进行因次处理,使各项式子基本量纲都有相同的幂次,即使方程达到无量纲化。
According to the governing equation of axially moving strings, introduce the non-dimemsional variables and parameters, where L is displace, T is time. and M is mass. Substituting non-dimensional vairables and parameter into governing Equation and transforming the resulting equation into the dimensionless, from this we can get the dimensionless governing equation.
