摘要
用点变换理论分析气镐的动力过程,讨论气镐正常起动和稳定工作的条件。对气镐活塞和配气阀的动力过程进行计算机仿真。通过仿真进行气镐的计算机辅助设计,并达到了较高的精度。
The dynamic process of pneumatic pick and the conditions under which the normal starting and stable working are available are discussed by way of the theory of point transformation. A computer simulation was carried out for the dynamic processes of piston and distributing value. An analytical relationship between structural parameters and performance indices is thus established.according to the one-dimensional gas dynamic theory, with CAD achieved with accuracy.
