Research and Design of Hydraulic Impact Mechanisms

This book is a culmination of the author’s many years of research in hydraulic impact mechanisms. It provides an in-depth and comprehensive study of the working mechanism of hydraulic impact structures, introducing the coefficients β and β1. The book establishes a more refined analytical method and design approach for solving hydraulic impact mechanisms. It takes into account the compression of hydraulic fluid and various operating conditions, constructing mathematical and simulation models for hydraulic impact mechanisms. Additionally, the book includes the development of simulation software that is not only practical for design purposes but also more accurate. The author delves into the analysis of some specific physical phenomena related to hydraulic impact mechanisms.

The book is of great assistance in the design and research of hydraulic impact mechanisms. It can serve as a design reference for relevant technical professionals and as a textbook for graduate students in related fields.
