Abstract
Aiming at the problem of large impact caused by the recovery of hydraulic support panel to the end, taking the mechanism of panel guard of ZY12000/28/63D hydraulic support as the research object, the working principle of buffer device is analyzed and its mathematical model is established. The hydraulic model of jack buffer device is built by using AMESim software, and the impact of buffer device on terminal impact is analyzed by running simulation. The results show that the buffering device can improve the problem of high impact recovery of the protective plate to the end and improve its working stability.关键词
