Abstract

The invention discloses a magneto-rheological damper composed of a stepped piston cylinder, and relates to the technical field of new energy automobile accessories, the magneto-rheological damper comprises the piston cylinder composed of an end cover and a cylinder barrel, a piston rod provided with a hanging ring, and a magnetic conductive ring provided with a plurality of coils, the piston cylinder is designed into an inner barrel with three different inner diameters, and a heat dissipation layer is arranged on the outer side of the cylinder body. The defect that heat in the steel body cannot be dissipated in time is overcome. An S-shaped transition curve is optimized at the change position of the inner diameter of the inner side of the cylinder body by using a genetic algorithm and a polynomial fitting principle and is applied to the joint position of the inner wall of the cylinder barrel. The magnetorheological fluid is combined with the damper, so that the damper can change damping in real time, vibration generated by road condition changes in the driving process of an automobile is reduced, the comfort experience of a user is improved, the structure is simple, and the self-adaptive capacity is high.

Description

technical field [0001] The invention relates to the technical field of new energy automobile parts, in particular to a magnetorheological damper composed of a stepped piston cylinder. Background technique [0002] In today's society with highly developed technology, new energy vehicles have become a more popular travel tool. In the development and use of new energy vehicles, the safety of new energy vehicles and the comfort of customers are two very important indicators. In terms of customer comfort, dampers are a key accessory to reduce vibration. The traditional damper or hydraulic damper cannot reasonably adjust the damping size according to the actual road conditions, and does not satisfy the adaptive adjustment. The magnetorheological damper can change the viscosity of the working fluid by using the smart material magnetorheological fluid and introducing an external magnetic field, so as to achieve the required damping force in the actual working condition. Therefore...
