IDENTIFYING THE BASIC PARAMETERS OF SELF-REGULATING DAMPERS IN CONSTRUCTION MACHINERY

Abstract

Used in mechatronics systems, self-regulating dampers are capable of braking in both directions and automatically adjusting the resistance force when the velocity and mass of the actuator change, helping vehicles to avoid being impacted by the external environment and mitigating the judder phenomenon caused by complex terrain. However, the application of self-regulating damper equipment in Vietnam is still limited, especially in the field of construction machinery, so excavators have to work on unfavourable terrain and are negatively affected by external forces, which leads to instability and a lack of balance during soil extraction. Therefore, this article conducts a survey of some basic parameters of self-regulating dampers in construction machinery, the adjustibility of these parameters and the appropriate paramaters for operating such equipment. This article also serves as a theoretical foundation for designing self-regulating dampers in Vietnam.
