弦是乐器中最常见的元素之一，弦动力学的适当物理描述对于建模，分析和仿真至关重要。对于单一极化的线性振动，最常见的模型是基于张力下的欧拉-伯努利梁方程。尽管其形式简单，这样的模型给出了无界的相速度和群速度在大波数，这样的行为可以被解释为非物理的。因此，在最近的作品中，已经采用了Lishenko模型来克服这种缺点。本文提出了基于剪切梁方程的第三种模型。这三个模型在这里进行评估和比较关于音乐声学的感性考虑。
Strings are amongst the most common elements found in musical instruments and an appropriate physical description of string dynamics is essential to modelling, analysis, and simulation. For linear vibration in a single polarisation, the most common model is based on the Euler-Bernoulli beam equation under tension. In spite of its simple form, such a model gives unbounded phase and group velocities at large wavenumbers, and such behaviour may be interpreted as unphysical. The Timoshenko model has, therefore, been employed in more recent works to overcome such shortcoming. This paper presents a third model based on the shear beam equations. The three models are here assessed and compared with regard to the perceptual considerations in musical acoustics.
