Abstract: A force-balance friction model for the simulation of dynamic mechanical systems is presented. An extension of Karnopp’s model (1985), it can be applied to multi-degree-of-freedom vibration systems ...

Abstract: With the aim of seeking a more reasonable solution for the squeeze film force for large amplitude motion with low viscosity fluids, an elliptical velocity profile and the corresponding squeeze ...

Abstract: A rotating shaft vibrating in a squeeze film bearing and a tube in a heat exchanger oscillating with fluid-filled cylindrical supports both involve cylindrical squeeze films. Many theoretical ...

Abstract: An algorithm has been developed to simulate the normal approach, contact, and rebound of lubricated cylinders. The detailed interaction between the lubricated cylinders is predicted, thus providing ...

Abstract: This paper describes the use of a “self-formulating” computer program, PLANET II, in the simulation of mechanisms with clearances in the revolute connections. The PLANET II program is based on ...

Abstract: This paper addresses the question of damping of multispan heat exchanger tubes with liquids (mostly water) on the shell side. The different energy dissipation mechanisms that contribute to damping ...

Abstract: Tubes within tube and shell heat exchange components are supported at intermediate points by support plates. Flow-induced vibration of a tube can cause it to impact or rub against a support ...
