Research and Design of Hydraulic Impact Mechanisms
Qinghua He
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...
