漂木撞击力量测方法及撞击力特性研究

摘要

提出利用钟摆原理模拟漂木撞击漂木道的过程，从而直接测定撞击力的方法.介绍研制的应变式撞击力传感器的构造及其主要技术性能，将其应用于太平驿漂木道模型漂木撞击力的测试.根据实测资料，分析了斜向撞击力与撞击角、门顶潜没深度以及库水位的变化关系，得出单位体积内单位速度漂木撞击力只与撞击角有关，并给出其与撞击角的关系式.%The structure and performance of a transducer designed for the measurement of float timber percussive forces are introduced. Based on the application of the transducer to the Taipingyi float timber canal model, the characteristics of percussion and the relationship between the float timber percussion of unit volume, unit velocity and the percussion angle are analyzed.
