Introduction
What is vibration engineering?
Vibration engineering is a branch of engineering that deals with the study of vibrations and their effects on structures, machines and systems. Vibrations are oscillations or periodic motions of objects or media around an equilibrium position. They can be caused by various sources, such as forces, impacts, loads, disturbances, noise or natural phenomena. Vibrations can have positive or negative effects on the performance, safety, reliability and comfort of engineering systems. For example, vibrations can be used to generate electricity, test materials, measure properties, control devices or enhance sensations. On the other hand, vibrations can also cause damage, wear, fatigue, failure, noise or discomfort.
Who is Andrew D. Dimarogonas?
Andrew D. Dimarogonas was a Greek-American professor of mechanical engineering at Washington University in St. Louis. He was born in 1938 in Athens and received his bachelor's degree from the National Technical University of Athens in 1961. He then moved to the United States and earned his master's and doctoral degrees from Northwestern University in 1963 and 1966 respectively. He joined Washington University in 1967 and became a full professor in 1975. He was also a visiting professor at several universities around the world, such as Stanford University, University of California at Berkeley, Massachusetts Institute of Technology and Imperial College London. He was an internationally recognized expert in vibration engineering, rotor dynamics, control theory and applied mechanics. He published over 200 papers and 10 books on these topics. He received many awards and honors for his contributions to engineering education and research, such as the ASME Worcester Reed Warner Medal, the ASME Adaptive Structures Prize and the ASME Lyapunov Award. He died in 2000 at the age of 62.
What is his book about?
One of his most influential books is Vibration For Engineers, which was first published in 1990 and revised in 1996. This book is intended for use on one- or two-term introductory courses in vibrations taught to mechanical, aerospace, engineering mechanics and civil engineering undergraduates. It covers the basics of vibration analysis and the design of machines, mechanical systems and structures, providing extensive coverage of classical subjects, such as single and multiple degree-of-freedom and continuous systems. It also introduces symbolic processing for those readers who want to extend their understanding of the fundamentals of vibration analysis. Symbolic processing is the use of computer algebra systems to manipulate mathematical expressions and equations symbolically, rather than numerically. This can help simplify complex problems, obtain exact solutions, explore alternative approaches and verify results. The book also includes historical references so that students will understand how vibration theories developed. It also emphasizes design and extends the discussion of design beyond handbook solutions for component sizing to include the assumptions underlying the handbook solutions. The book also features drill exercises, examples, problems, tables, figures and appendices to help students learn and apply the concepts and methods of vibration engineering.
Main body
Why is vibration engineering important?
Applications of vibration engineering
Vibration engineering has many applications in various fields and industries. Some examples are:
In aerospace engineering, vibration engineering is used to design and test aircraft, rockets, satellites and space vehicles that are subjected to various sources of vibrations, such as aerodynamic forces, propulsive forces, structural loads, thermal effects and acoustic noise. Vibration engineering can help improve the performance, stability, safety and durability of these systems.
In mechanical engineering, vibration engineering is used to design and analyze machines and mechanisms that involve moving parts, such as engines, turbines, pumps, compressors, gears, bearings, robots and vehicles. Vibration engineering can help optimize the efficiency, reliability, noise reduction and vibration isolation of these systems.
In civil engineering, vibration engineering is used to design and evaluate structures and infrastructures that are exposed to dynamic loads, such as earthquakes, wind, traffic and human activities. Vibration engineering can help enhance the strength, stiffness, damping and resilience of these systems.
In biomedical engineering, vibration engineering is used to study and manipulate the vibrations of biological tissues and organs, such as bones, muscles, nerves and blood vessels. Vibration engineering can help diagnose diseases, monitor health conditions, stimulate healing processes and deliver drugs.
In electrical engineering, vibration engineering is used to generate and convert electrical energy using piezoelectric materials that produce electric charges when subjected to mechanical stress or strain. Vibration engineering can help create self-powered devices, sensors and actuators that harvest energy from ambient vibrations.
Challenges of vibration engineering
Despite its many benefits and applications, vibration engineering also faces some challenges and limitations. Some examples are:
Vibration engineering often involves complex nonlinear phenomena that are difficult to model, analyze and control accurately. For instance, some vibrations may exhibit chaotic behavior or bifurcations that lead to unpredictable outcomes or sudden changes in system dynamics.
Vibration engineering often requires sophisticated experimental techniques and equipment to measure and manipulate vibrations in real-world settings. For instance, some vibrations may be too small or too fast to be detected by conventional sensors or actuators.
Vibration engineering often involves trade-offs between conflicting objectives or constraints that need to be balanced carefully. For instance, some vibrations may be desirable for certain functions but undesirable for others. For example, increasing the stiffness of a structure may improve its resistance to external disturbances but also increase its natural frequency and susceptibility to resonance.

FAQs
Here are some frequently asked questions and answers about the topic of this article:
What is the difference between vibration and oscillation?
Vibration and oscillation are both terms that describe periodic motions of objects or media around an equilibrium position. However, vibration is usually used to refer to small-amplitude motions that are caused by external forces or disturbances, while oscillation is usually used to refer to large-amplitude motions that are caused by internal forces or restoring mechanisms.
What are the types of vibrations?
There are two main types of vibrations: free and forced. Free vibrations occur when a system is set into motion by an initial disturbance and then left to vibrate on its own. Forced vibrations occur when a system is subjected to a continuous or periodic external force that maintains its motion. There are also other types of vibrations, such as damped, undamped, linear, nonlinear, deterministic, stochastic, harmonic, nonharmonic, etc.
What are the methods of vibration analysis?
There are many methods of vibration analysis that can be used to study the characteristics and behavior of vibrating systems. Some examples are: modal analysis, frequency analysis, time-domain analysis, spectral analysis, wavelet analysis, finite element analysis, etc.
