空气锤活塞运动规律研究

为了进一步研究空气锤气室和活塞设计参数对空气锤性能的影响,以KQC系列空气锤为例,在空气锤活塞与气室的物理模型和数学模型的基础上,利用VC++编程软件对空气锤的气室状态和活塞运动规律进行了仿真计算并对计算输出数据进行处理,得出空气锤性能参数曲线,由性能参数曲线分析得出空气锤的内部设计参数与空气锤性能参数之间的关系。研究结果为空气锤的进一步改进和完善提供了理论依据,也为空气锤现场应用中及时调整部分结构参数以保证空气锤的正常工作和快速钻进提供了依据。

Research on the movement law of the air hammer piston

To make a further study of the effect of the air hammer's air chamber and the piston's design parameters on the performance of the hammer,a simulation calculation of the air chamber state of the hammer and the piston's motion law was conducted by taking the series of KQC air hammers as an example and adopting the physical and mathematical models of air hammer's piston and air chamber together with the VC++ programming software. The output data obtained by calculation were processed to derive the parametric curve for the hammer's performance,from which the relation between the hammer's inner design parameters and performance parameters was obtained so as to provide the theoretical basis for making further improvements of the hammer.
