NUMERICAL STUDY INTO DYNAMICS OF SELF-OSCILLATORY HYDROPERCUSSION SYSTEMS--PART I: DOUBLE-ACTING SYSTEMS

摘要

The mathematical model of a 3-D self-oscillatory double-acting hydropercussion system is presented. The dynamic simulation criteria are determined, and the output characteristics of the system are studied numerically in the space of these criteria. The research has revealed a number of the behavioral features of the system in the space of the main simulation criteria, as well as the influence exerted by the mechanical friction, impact velocity recovery factor and other parameters on the output characteristics of the system.
