DYNAMIC MODELING OF THE ELECTRO-HYDRAULIC VIBRATION EQUIPMENT

Abstract

Electro-hydraulic vibration equipment is widely used in vibration
environment simulation tests, due to its large output power, displacement
and thrust, as well as good workload adaptation and multi-controllable
parameters. This paper presents a mathematical model of an electro-
hydraulic vibratory exciter used for vibration testing of steel piles on coral
reefs. Based on this model of electro-hydraulic vibrator, we have built
characteristic curves to evaluate the stability of the system, the quality of the
transition process, as well as parameters - amplitude, frequency. The research
results are the scientific basis for design of electro-hydraulic vibratory exciter
for vibration testing of steel piles in the coral foundation.
