Victor台式计算机可用于数值模拟接杆凿岩。活塞、钎尾及接杆是均质的,特性阻抗相同,接杆套及钎头也是如此。两个效率由下面6个参变量的函数决定:接杆套数、接轩套-活塞长度比、接杆套-钎杆特性阻抗比、钎头和岩石之间最初的间隙、钎头-岩石间的相互作用(两个参数)。第一个效率定义为对岩石所作的功与活塞冲击能的比值;第二个效率建立在对岩石所作的功与活塞的反弹动能这二者之和的基础上——假定是完
Victor desktop computers can be used to numerically simulate post rock drilling. Piston, shank and rod after the rod is homogeneous, the same characteristic impedance, the rod sleeve and the first bit is also true. The two efficiencies are determined as a function of the following six variables: number of posts, number of connection yokes - length ratio of the piston, post-sleeve characteristic impedance ratio, initial gap between the bit and the rock, Interaction (two parameters). The first efficiency is defined as the ratio of work made to rock to piston impact energy. The second is based on the sum of the work performed on the rock and the kinetic energy of the piston’s rebound
