The invention discloses a method and a device for evaluating the vibration performance of a steering wheel, belonging to the field of automobiles. The method includes: establishing an NVH finite element model related to steering wheel chattering performance in a computer-aided system based on the vehicle structure; determining the corresponding simulation operations of the factors that cause steering wheel chattering in the NVH finite element model; By simulating the operation, the vibration velocity response of the steering wheel corresponding to the factors causing the steering wheel vibration is obtained; the vibration velocity response of the steering wheel is evaluated according to the steering wheel vibration velocity response of the vehicle. By establishing an NVH finite element model related to the steering wheel chattering performance, and based on the simulation operation of the factors that cause steering wheel chattering in the NVH finite element model, the steering wheel chattering performance of the vehicle is evaluated to ensure that it can be used in the design of the vehicle. Evaluation of steering wheel vibration performance in the early stage can not only reduce the cost of vehicle production, save a lot of staff energy, but also shorten the production cycle of the vehicle.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to a method and device for evaluating the chattering performance of a steering wheel. Background technique [0002] With the improvement of people's living standards, passengers have increasing requirements for vehicle driving comfort, driving stability and NVH (Noise, Vibration, Harshness, noise, vibration and harshness) performance. While the car is running, the steering wheel buffeting can be directly felt by the driver, and directly affects the subjective evaluation of the passengers on the above-mentioned performance of the vehicle. Therefore, during the development and use of the vehicle, the buffeting performance of the steering wheel of the vehicle is often evaluated. [0003] In the related art, when evaluating the buffeting performance of the steering wheel, it is mainly realized through the subjective feeling of passengers, that is, the passenger feels the degree of ...
