Problems solved by technology

For some vehicles, such as All-Wheel Drive (AWD) vehicles with longitudinal drive shafts, or two-wheel drive vehicles with wheel-side drive shafts, torsional resonance often exists between the longitudinal drive shafts and the wheel-side drive shafts. This affects the NVH performance of the vehicle

Abstract

The invention discloses a parameter configuration method. The method comprises the following steps: acquiring a transmission model corresponding to a transmission system; determining a torsional vibration free mode of each order of the transmission system according to the transmission model, wherein the torsional vibration free mode at least comprises a torsional vibration inherent frequency; predicting a torsional vibration risk point of the transmission system at a common rotating speed based on the vibration mode corresponding to the torsional vibration inherent frequency; establishing a torsion resonance part according to the torsion risk point, and establishing a damping model for a damping system according to the torsion resonance part and the transmission model, wherein the dampingsystem comprises the transmission system and a torsion damper; determining the damping effect of different parameter combinations on the transmission system according to the damping model; and determining a target parameter combination from the parameter combinations according to the damping effect, and configuring the torsional damper according to the target parameter combination. By designing proper TVD parameters, the torsional vibration amplitude of a longitudinal transmission shaft or a wheel-side driving shaft of a transmission system is attenuated, the NVH performance of the whole vehicle is improved, and the development efficiency is improved.

Description

Technical field [0001] The present application relates to automotive sectors, in particular, to a parameter configuration, device and vehicle. Background technique [0002] With the development of science and technology, vehicles have gradually become a major transportation of travel or logistics transportation. Among them, the noise of the vehicle, the performance of the Vibration Harshnes, NVH is gradually become an important consideration for consumers to buy vehicles. [0003] NVH performance is directly related to the vehicle drive train. The so-called transmission system, also known as the transmission system, refers to a device located between the engine to the vehicle drive wheel, which is the basic function thereof, that is, the driving force of the engine is received and transmitted to the drive wheel. For some vehicles, such as all-Wheel Drive, AWDs having a vertical drive shaft, or a two-wheel drive shaft with a wheel drive shaft, a longitudinal drive shaft and a whee...
