Features

  • Explains the laws governing how friction and lubrication interact with each other
  • Highlights a model that studies the compliance of a few elements of the machine
  • Discusses the problem of backlash where in the several phases of motion in various mechanical elements are completely separated from each other
  • Describes calibration systems that allow the avoidance of the introduction of errors in the system by other parameters
  • Underlines how sometimes the combined effects of the disturbing actions, such as backlash and compliance, could be particularly harmful to the dynamics of the system
  • Explores how dynamic behavior of the motor is considered the effect of its own characteristic
  • Includes extensive references at the end of each chapter

Summary

In the real world the dynamic behavior of a real machine presents either unforeseen or limiting phenomena: both are undesired, and can be therefore be classified as parasitic phenomena — unwanted, unforeseen, or limiting behaviors. Parasitic Phenomena in the Dynamics of Industrial Devices describes the potential causes and effects of these behaviors and provides indications that could minimize their influence on the mechanical system in question.

The authors introduce the phenomena and explore them through real cases, avoiding academic introductions, but inserting the entire academic and experimental knowledge that is useful to understand and solve real-world problems. They then examine these parasitic phenomena in the machine dynamics, using two cases that cover the classical cultural division between cam devices and mechanisms. They also present concrete cases with an amount of experimental data higher than the proposed ones and with a modern approach that can be applied to various mechanical devices, acquiring real knowledge superior to one of the mere finite element systems or collections of mechanical devices.

  • Organizes machine dynamics through systems theory to give a comprehensive vision of the design problem
  • Details machine dynamics at an advanced mathematics level and avoids redundancy of fundamental knowledge
  • Introduces real machine cases for solutions to practical problems
  • Covers two broad classes of mechanical devices that are widely used in the construction of instrumental goods
  • Employs a mechatronic approach that can be applied to electro-mechanical, hydro-mechanical, or pneumo-mechanical machines

Highlighting industrial devices in the manufacturing industry, including industrial indexing devices and industrial robots, the book offers case studies, advanced models, design methods, and short examples of applications. It is of critical importance for any manufacturing enterprise that produces significant amounts of objects through a process with one or more automated phases.
