Monitoring of bolt looseness is essential for ensuring the safety and reliability of equipment
and structures with bolted connections. It is well known that tangential damping has an …

An increasing demand for high-quality, low cost Earth imagery has led to the requirement for
improved structural stability of the satellite instruments providing the imagery. This translates …

连接界面上存在的跨尺度, 多物理场和非线性行为是引起结构复杂非线性动力学的主要原因.
由于连接界面力学行为的复杂性, 以及对连接界面进行直接试验观测的困难 …

We investigate the inter-particle tangential force–displacement behavior of a broad range of
granular materials. The major experiments are conducted using a custom-built …

Obtaining the static hysteresis behavior of bolted joint and identifying joint parameters are of
great significance to design and formulate the assemble process for the bolted joint. In this …

Mechanical joints in assembled structures cause energy dissipation due to micro-slip in
contact and softening effects that play an important role in the dynamic behavior of such …

This paper presents an experimental analysis performed on a simplified brake apparatus. In
past years a common approach for squeal prediction was the complex eigenvalues analysis …

The complex frictional stick-slip behaviors of mechanical joint interface have a great effect
on the dynamic properties of assembled structures. In this paper, a reduced-order modeling …

Electromagnetic shunt damper (EMSD) offers flexible tunability of linear damping. The low
damping force-to-mass ratio of the EMSD, however, hinders those applications which …

Stresses produced by the forced vibrations can lead to a significant reduction of the life of
turbo engine blades. To predict the vibration amplitudes of this components an accurate …
