Embodiment Construction

[0039] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific examples, but the implementation of the present invention is not limited thereto.

[0040] like figure 1 As shown, a frequency-adjustable symmetrical vehicle engine shock absorber of the present invention includes a mounting base 2, a corner iron core 3, a straight iron core 4, a DC coil 5, a first elastic body mounting base 6, and a connecting rod 7 , the magnetorheological elastomer 8 and the second elastomer installation base 9 .

[0041] The mounting base 2 is a "T"-shaped mounting support, and the bottom is provided with 4 through holes through which 4 screws connect the vibration absorbing device with the engine top cover. The upper surface of the bottom is a straight rectangular cantilever, and the first elastic mounting base 6 and the second elastic mounting base 9 are fixedly connected to the cantilever.

[0042]The first elastic body mou...

Abstract

The invention discloses a frequency-adjustable symmetric vehicle engine vibration absorber, and belongs to the field of engine vibration control. The frequency-adjustable symmetric vehicle engine vibration absorber comprises a mounting seat (2), two elastic body mounting bases, corner iron cores (3), straight iron cores (4), direct current coils (5), magnetorheological elastic bodies (8) and connecting rods (7). The working mode of each of the magnetorheological elastic bodies is the shear mode, and the problem that the elastic bodies are easy to fall off is solved by adopting the structural design. The frequency-adjustable symmetric vehicle engine vibration absorber has the benefits as follows: by adjusting the electric current in the direct current coils, the intrinsic frequency of the vibration absorption device is changed, and a condition for forming an internal resonance is established; besides, the characteristics that the energy consumption is low, the working frequency band is wide and the vibration adsorbing effect is good are achieved.

Description

technical field [0001] The invention belongs to the technical field of mechanical vibration, and in particular relates to a frequency-adjustable symmetrical vehicle engine vibration absorber. Background technique [0002] During the working process of the vehicle engine, it will vibrate under the action of inertial force. This vibration is transmitted to the body through the engine mount, and then causes the vibration of the vehicle. Drivers work in such an environment for a long time, easily feel fatigued, and traffic accidents occur. For engine vibration, there are mainly two solutions: vibration isolation and vibration absorption, and the vibration reduction effect of the latter is better than that of the former. [0003] In recent years, a new type of magnetorheological material, magnetorheological elastomer, has emerged. Magnetorheological elastomers are composite materials composed of polymer compounds and magnetic particles. Put the micron-sized magnetic particles ...
