立筒仓卸料时动态压力的理论研究

Theoretical Study on Dynamic Pressure of Silo Unloading

本文主要对立筒仓卸料时压力升高的原因进行分析研究, 以满储立筒仓卸料时的起拱机理为基础,根据卸料时储料能量转换原理, 考虑卸料过程中应力状态的转换, 解释立筒仓卸料时动态压力增大的原因,以期为研究动态压力沿仓高的变化规律提供参考理论.

This paper mainly analyzed the causes of pressure rise in the unloading of silos, based on the arching mechanism of the dump full of silos, according to the principle of energy conversion in the unloading process, considered the transformation of the stress state in the unloading process, and explained the reason for the increase of dynamie pressure in the unloading of silo, in order to study along the change rule of the height of the warehouse. the dynamic pressure. The reference theory was provided
