A Magnetorheological Damper Preventing Circumferential Sliding

Abstract

The invention provides a magnetorheological damper capable of preventing circumferential sliding. The magnetorheological damper comprises a piston rod, an iron core and a cylinder barrel which are arranged coaxially from inside to outside. According to the main technical scheme of the magnetorheological damper, two planes are symmetrically arranged on the outer wall of the lower end of the pistonrod, so that the outer wall of the lower end of the piston rod is in a shape of staggered combination of two curved surfaces and the two planes, the iron core is internally of a hollow structure, theinner wall of the iron core and the outer wall of the lower end of the piston rod are matched in shape, and the piston rod penetrates through the hollow structure of the iron core to mesh with the iron core. According to the magnetorheological damper, the piston rod and the iron core mesh with each other by changing a connection mode of the piston rod and the iron core, the connection mode of thepiston rod and the iron core is firmer, and circumferential sliding between the piston rod and the iron core can be effectively prevented.

Description

technical field [0001] The invention relates to the technical field of magneto-rheological dampers for vibration reduction systems, in particular to a magneto-rheological damper capable of preventing circumferential sliding. Background technique [0002] With the continuous progress and development of the economy and society, and the continuous improvement of people's living standards, more and more people begin to pursue high-quality life experience. Vibration problems exist in various mechanical systems, especially in vehicles such as automobiles and trains that are closely related to people's transportation. In order to provide a more comfortable experience for people, it is necessary to solve the existing vibration problems. The magneto-rheological damper is a shock absorber with better performance. It is a device that provides motion resistance to consume motion energy, and can have a significant vibration reduction effect. When the magneto-rheological damper is speci...

Problems solved by technology

However, such a connection method has the problem that the connection is not strong enough, and the phenomenon of circumferential sliding often occurs between the piston rod and the iron core, especially when the vibration frequency of the machine is too high, the circumference between the piston rod and the iron core Sliding in the opposite direction will cause damage to the mechanical structure of the magnetorheological damper, and will also reduce the damping value of the magnetorheological damper, thereby affecting the vibration reduction effect
