Abstract

The invention discloses a design method of a composite vibration damper and the composite vibration damper. The design method comprises the following steps of a, debugging torsional vibration parameters of the composite vibration damper according to the torsional resonance frequency of a transmission system when the transmission system has NVH complaint, and obtaining a torsional vibration parameter range; b, debugging radial vibration parameters of the composite vibration damper according to the radial resonance frequency of the transmission system when the transmission system has NVH complaint, and obtaining a radial vibration parameter range; c, according to the torsional vibration parameter range and the radial vibration parameter range, obtaining verification parameters of the composite vibration damper when both the torsional vibration and the radial vibration meet the shock absorption requirements, and according to the verification parameters, obtaining composite vibration reduction conditions; and d, according to the verification parameters, obtaining the composite vibration reduction conditions, and according to the composite vibration reduction conditions, trial-manufacturing a sample piece for loading verification. All parameters of the torsion vibration damper are adjusted to reach the expected range, and the purpose that one composite vibration damper is used for restraining radial vibration and torsion vibration at the same time is achieved, so that a radial vibration damper is omitted, and cost is saved.

Description

technical field [0001] The invention relates to the technical field of damping of automobile transmission systems, in particular to a design method of a composite shock absorber and the composite shock absorber. Background technique [0002] In the prior art, the torsional vibration and radial vibration of the transmission system are considered separately, that is, the torsional vibration damper (TVD) is used to suppress the torsional vibration, which only has the function of suppressing torsional vibration damping; the radial vibration damper (TVD) Damper) to suppress radial vibration, only the function of suppressing radial vibration. Contents of the invention [0003] The purpose of the present invention is to solve the problem of high gravity and high cost caused by separately setting related components for the torsional vibration and radial vibration of the transmission system in the prior art. By adjusting the various parameters of the torsional vibration damper to ...
