Abstract

The experience of high-frequency pneumatic hammer design to run on increased compressed-air pressure is reviewed. Arrangement of a coupled shock-pulse generator composed of two pneumatic hammers is described, and its stable operation conditions are determined. The synchronized operation of the hammers in the coupled generator is implemented through the smooth percussion frequency control of one of the hammers. After the accomplished research into interaction between soil and some prototype models with two percussion masses, a fully phase- and frequency synchronized machine has been designed.

基于锤-土相互作用物理模拟的高能气动锤设计

摘要

回顾了高频气动锤设计在增加的压缩空气压力下运行的经验。描述了由两个气动锤组成的耦合冲击脉冲发生器的布置，并确定了其稳定运行条件。耦合发电机中的音锤的同步操作是通过其中一个音锤的平滑敲击频率控制来实现的。在对土壤与一些具有两个冲击质量的原型模型之间的相互作用进行了完整的研究后，设计了一个完全相位和频率同步的机器。
