Application of shape optimization to brake squeal phenomena
Nihon Kikai Gakkai ronbunshu, 2015 The present paper describes an application of non-parametric shape optimization to disc brake squeal phenomena. The disk brake squeal is known as self-excited vibration; the real and imaginary parts of the complex eigenvalue indicate the damping ...

Stability analysis of pantograph under frictional force
Nihon Kikai Gakkai ronbunshu, 2019 The frictional force acts to the travelling pantograph head in horizontal direction due to sliding of the pantograph head and contact wire. Therefore, vertical motion of the pantograph head is generated by link mechanism of the pantograph.

Parameter Identification of Brake Pad Shims for Complex Eigenvalue Analysis [PDF]
PAMM, 2019 AbstractComposite structures called shims are bonded to brake pad backplates to increase the damping in brake systems. The aim of this measure is to avoid squeal which is a high‐frequency audible brake vibration disturbing customers and the environment. This NVH problem originates from self‐excited vibrations resulting from the friction contact between

Buckling Analysis of Piles in Multi-Layered Soils
Applied Sciences, 2021 Pile buckling is infrequent, but sometimes it can occur in slender piles (i.e., micropiles) driven into soils with soft layers and/or voids. Buckling analysis of piles becomes more complex if the pile is surrounded by multi-layered soil.

Complex eigenvalue analysis of railway wheel/rail squeal
International Journal of Engineering, Science and Technology, 2016 Wheel/rail squeal noise of trains is one of the challenging problems of trains, but a successful model for the squeal problem has not been presented until now. In this study, a new approach was presented to investigate the basic mechanism of the wheel/rail squeal noise, using complex eigenvalue analysis by the finite element method.
