Embodiment Construction

[0023] see Figure 1 to Figure 3 , is an embodiment of a device for testing the cushioning properties of magnetorheological elastomers, including a base 7, an upper beam 2, and at least two columns 22 connected to the base 7 and the upper beam 2. In this embodiment, the column The number is two, and the base is designed as a strip to reduce the footprint of the base. The upper and lower ends of the two columns are respectively connected to the upper beam and the base by bolts. A linear slide rail 5 is erected between the base 7 and the upper beam 2, the upper end of the linear slide rail 5 is fixedly connected to the upper beam 2, and the lower end of the linear slide rail 5 is fixedly connected to the base 7. In this embodiment, the straight line The upper and lower ends of the slide rail are fixedly connected to the upper beam and the middle end of the base by bolts respectively, so that the force bearing effect is better.

Abstract

The invention discloses a device for testing the buffer performance of a magnetorheological elastomer. The device for testing the buffer performance of the magnetorheological elastomer comprises a base, an upper cross beam and upright posts connected onto the base and the upper cross beam, wherein the upper end of a linear sliding rail is fixedly connected with the upper cross beam; the lower end of the linear sliding rail is fixedly connected with the base; a shock motion rack is in sliding fit with the linear sliding rail; the shock motion rack comprises a hitting base, an upper shelf board and support pillars connected with the base and the upper shelf board; the magnetorheological elastomer is fixed on the upper shelf board; a mass block is fixed on the magnetorheological elastomer; a first acceleration sensor is fixed on the mass block; a lifting seat is arranged on the hitting base; the lower part of the lifting seat is in threaded fit with the hitting base through a screw; the upper part of the lifting seat is a fixed tray; a permanent magnet is fixed on the fixed tray in a magnetic adsorption manner; a second acceleration sensor is fixed on the hitting base. The device for testing the buffer performance of the magnetorheological elastomer can test the buffer performance of the magnetorheological elastomer in magnetic fields with various intensities.

Description

technical field [0001] The invention relates to the field of magnetorheological elastomers, in particular to a device for testing the cushioning performance of magnetorheological elastomers. Background technique [0002] Shock is a phenomenon in which force, displacement, velocity, and acceleration change suddenly when the system is subjected to transient excitation, and it is also a process of sudden release of energy. Response to brief pulses, steps, or transient aperiodic stimuli. Although the system vibration caused by the shock response can disappear quickly, the maximum stress caused by it is likely to damage the system. Therefore, it is necessary to try to control the harm caused by the shock, that is, to study the buffer technology. The development of buffer technology is of great significance to national defense construction, aerospace technology research and further development of industrial technology. As the key equipment of buffering, buffer plays a pivotal r...
