Collisions are an innate part of the function of many musical instruments. Due to the
nonlinear nature of contact forces, special care has to be taken in the construction of …

This article is concerned with the vibration of a stiff linear string in the presence of a rigid
obstacle. A numerical method for unilateral and arbitrary-shaped obstacles is developed …

A numerical model of a tanpura string is presented, based on a recently developed, stability-
preserving way of incorporating the non-smooth forces involved in the impactive distributed …

When a building sways due to strong wind or an earthquake, the elevator rope can undergo
resonance, resulting in collision with the hoist-way wall. In this study, a hard stopper and a …

The grand piano action aims at propelling the hammer up to the strings. This mechanism
provides the pianist with a high-controllability of the time of impact of the hammer with the …

Many engineering applications make use of fiber assemblies under compression.
Unfortunately, this compression behavior is difficult to predict, due to nonlinear compliance …

The present project has been achieved in close collaboration with the MIM, the Musical
Instruments Museum of Brussels. Thanks to our multibody modeling and analysis …

A computationally efficient technique to simulate the dynamic response of a beam colliding
with rigid obstacles is described in this paper. The proposed method merges three key …

Ancient musical instruments can tell us much about the way composers of the past centuries
wrote their music. Indeed, the sound and playing characteristics of historical instruments are …

力积分法和振型转换法是处理连续体撞振问题的常用方法. 虽然作者已在前期提出了相对振型
转换法, 进一步扩展了传统振型转换法的适用范围, 但尚未对其与力积分法求解结果差异进行 …
