The author takes you on a heavy journey into probability theory. Covering single and multiple random variables. All the way up to describing the Central Limit Theorem and its uses, like Chi squared distributions. He builds on these to explain random time processes and ergodic distributions. Then in the frequency domain, we see spectral density functions and the concept of a stationary process.

All this in the first half of the book is more general than just for analysing vibrations. It could easily apply to communications theory, for example.

It is only in the second half that we get to studying random vibrations. In single and then multiple degree of freedom systems. Overall, you need a strong mathematical background before commencing this book, as well as several courses in mechanical engineering.

As a mechanical engineer, I had very little experience with random processes other than sampling distributions for experiments. The text builds up from the fundamentals of probability to introduce the fundamentals of random vibration. The preliminary material is essential to understanding the actual random vibrations material later. The author makes an effort to present the material in a concise and readable manner. One of few texts I own that I can read all the way through. Highly recommended.

It's a good problem solving book but not much on theory. However if you have background of probability of statistics, this can be a good reference.
