偏载工况下液压支架特性试验分析

Test and Analysis of Hydraulic Support Characteristics under Eccentric Load Condition

根据液压支架原型试验测定了支架在偏载工况下支护性能及压缩特性的变化规律,实测数据表明,偏载工况下,初撑力大小是支架支护性能能否及时发挥的关键参数;偏载工况下,顶板的下沉量同时受支架压缩量和顶梁变形量的影响。

Based on the prototype test of the hydraulic support,the change of the supporting performance and compression characteristics of the support under the eccentric load condition is measured,the measured data show that under the eccentric load condition,the initial support force is the key parameter that can support the performance of the support in time,and under the eccentric load condition,the roof subsidence is affected by both the compression of the support and the deformation of the roof beam.
