Problems solved by technology

[0003] The vibration-absorbing frequency of existing vibration-absorbing devices is mostly a relatively single frequency, which can only control vibration and noise within a narrow frequency range. Poor, so it is difficult to better solve the technical problems of resonance, abnormal sound, roar, etc. of the suspension system in multiple frequency bands

Embodiment Construction

[0060] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0061] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or there may be an intervening element at the same time. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

[0062] In the description of the present invention, it should be understood that the terms "first" and "second" are used for description purposes only, and cannot be interpreted as indicating ...

Abstract

The present invention provides a shock absorbing device, comprising: a plurality of shock absorbing units, the shock absorbing unit includes a mass body and an elastic body, the mass body is connected to the elastic body and supported by the elastic body, and the shock absorbing unit can The elastic body is connected to the target suspension system so as to be suspended on the target suspension system, and a plurality of the vibration-absorbing units are arranged at intervals on the vibration transmission path of the target suspension system. The vibration-absorbing device can use a plurality of the above-mentioned vibration-absorbing units to counteract multiple frequencies on the vibration transmission path of the suspension system, so that the fluctuation amplitude of the suspension system in the entire frequency range is reduced, thereby reducing the vibration of the suspension system and the vibration caused by the vibration. Noise, so that the suspension system meets the vibration isolation requirements. The invention also provides a design method of the vibration absorbing device and an automobile with the vibration absorbing device.

Description

technical field [0001] The invention relates to the technical field of vibration absorption, in particular to a vibration absorption device, an optimal design method of the vibration absorption device and an automobile with the vibration absorption device. Background technique [0002] When there is an external excitation, for a suspension system equipped with a vibration-absorbing device, the inertial force generated by the relative motion of the vibration-absorbing device can react on the suspension system, thereby avoiding strong vibration and noise of the suspension system due to resonance. . [0003] The vibration-absorbing frequency of existing vibration-absorbing devices is mostly a relatively single frequency, which can only control vibration and noise within a narrow frequency range. Poor, so it is difficult to better solve the technical problems of resonance, abnormal sound, roar, etc. of the suspension system in multiple frequency bands. Contents of the inventi...
