RETRACTION: Y. Li, Z. Bin, and Y. Tu, “Research on Impact Performance of Hydraulic Rock Drill with Floating Characteristics of Double Damping System,” Shock and Vibration 2019 (2019), https://doi.org/10.1155/2019/2942890.
The above article, published online on 7 November 2019 in Wiley Online Library (https://wileyonlinelibrary.com), has been retracted by agreement between the authors; the journal’s Editor-in-Chief, Huu-Tai Thai; and John Wiley & Sons Ltd.
The retraction has been agreed due to errors in the scientific content of the manuscript. Specifically, the authors identified that the inflation pressure of the accumulator was not considered as a necessary condition for the dynamic characteristics of the buffer system presented in Section 3. This directly affects the conclusions of the article and necessitates its retraction.
