Effects of Impact on the Behavior of a Flexible Multiple Disk Clutch and Brake
(The American Society of Mechanical Engineers (ASME), 1987)This paper discusses the dynamic behavior of a flexible multiple disk clutch subjected to dynamic loads. The expressions for obtaining the dynamic response and the transmission torque of the ... -
Vibrational Energy Transmission and Mode Conversion at a Corner-Junction of Square Section Rods
(The American Society of Mechanical Engineers (ASME), 1987)The low frequency reflection and transmission of vibrational energy at an L-junction of square section rods is investigated theoretically and experimentally. The theoretical description, in which ... -
Analysis of Lined Ducts With Mean Flow, With Application to Dissipative Mufflers
(The American Society of Mechanical Engineers (ASME), 1987)Mufflers with at least one acoustically absorptive duct are generally called dissipative mufflers. Generally, for want of systems approach, these mufflers are characterized by transmission loss ... -
Using Transfer Matrices for Parametric System Forced Response
(The American Society of Mechanical Engineers (ASME), 1987)For many years, engineers and scientists have sought to deal with the many phenomena exhibiting parametric characteristics. While many approximate techniques are available for the analysis of ... -
Dynamic Stability and Response of a Beam Subject to a Deflection Dependent Moving Load
(The American Society of Mechanical Engineers (ASME), 1987)The dynamic stability and transverse vibration of a beam subject to a deflection dependent moving load is considered. The deflection dependent moving load is motivated by the cutting forces in ... -
Vibration Control in Industrial Plant: A Methodological Approach
