Abstract

The invention relates to a performance-oriented optimization design method for a magneto-rheological damping unit. The method comprises the following steps: obtaining performance demands and required data of a user; determining an external design parameter and a to-be-optimized internal design parameter; performing dimensionless processing and determining a specific value or range; establishing a magnetic field intensity calculation model and the like of the damping unit; establishing a performance model of the damping unit; establishing and running an optimization parameter for a length-diameter ratio of the specific damping unit to obtain a corresponding optimization parameter and an optimized parameter; and finally within a given length-diameter ratio range, drawing out the corresponding optimization parameter and an optimization performance sensitivity curve, and according to an application environment and the like, flexibly determining the external design parameter on the performance sensitivity curve. The method can be applied to external (internal) coil type annular damping clearances, provides an accurate, reliable and clear dimensionless parameter influence curve for performance analysis of the magneto-rheological damping unit, and realizes optimization design of the magneto-rheological damping unit.

Description

technical field [0001] The invention relates to the field of parameter optimization design of magnetorheological fluid and hydraulic damping unit, and more particularly relates to a performance-oriented optimization design method of magnetorheological damping unit. Background technique [0002] The magnetorheological damping unit is a hydraulic control unit designed using the magnetorheological fluid effect. It is the core component of the magnetorheological valve and the magnetorheological damper. It can control the load on the magnetic current by changing the current in the excitation coil. Change the magnetic field in the fluid to change the damping characteristics of the fluid to achieve flow and pressure drop control. The magnetorheological damping unit with circular and disk-shaped liquid flow channels, due to its composite damping gap and the design of the magnetic ring, the shear area of ​​the magnetic field on the magnetorheological fluid increases, and the shearing...
