Mechanical Vibrations : Active and Passive Control

For all rotational machines, the analysis of dynamic stresses and the resulting vibrations is an important subject. When it comes to helicopters and piston engines, this analysis becomes crucial. From the design of parts working under stress to the reduction of the vibration levels, the success of a project lies mainly in the hands of the dynamicists. The authors have combined their talents and experience to provide a complete presentation on the issues involved. Part one describes, in concrete terms, the main dynamic phenomena and how they can be observed in reality. Part two presents information about the modeling methods required to understand the dynamic phenomena and develop solutions capable of eliminating the most serious effects.Content: Chapter 1 Unbalance and Gyroscopic Effects (pages 5–52): Chapter 2 Piston Engines (pages 53–73): Chapter 3 Dynamics of a Rotor (pages 75–118): Chapter 4 Rotor Control (pages 119–139): Chapter 5 Non?Homokinetic Couplings (pages 141–157): Chapter 6 Aerodynamic Excitations (pages 159–169): Chapter 7 Suspensions (pages 177–218): Chapter 8 Self?Tuning Systems (pages 219–238): Chapter 9 Active Suspensions (pages 239–251): Chapter 10 Absorbers (pages 253–277): Chapter 11 Self?Adjusting Absorbers (pages 279–287): Chapter 12 Active Absorbers (pages 289–318): Chapter 13 Resonators (pages 319–333): Chapter 14 Self?Adapting Resonators (pages 335–341): Chapter 15 Active Systems (pages 343–358): "This analysis of dynamic stresses on rotational machines such as helicopters and piston engines explains the main dynamic phenomena and how they can be observed in reality as well as information on the modeling methods required to understand the dynamic phenomena and develop solutions capable of eliminating the most serious effects." -- Publisher
