Fuel oil shaking noise simulation analysis method and platform and computer storage medium

Abstract

The invention discloses a fuel shaking noise simulation analysis method and platform and a computer storage medium. The method comprises the steps that a noise simulation model is established according to input fuel tank data of a vehicle; wherein the fuel tank data at least comprises bandage data, shock pad data and washboard data; fuel tank shell surface vibration data correspondingly output by the noise simulation model and node counterforce of the surface of a shock pad and a bandage mounting point are obtained according to input boundary conditions; wherein the boundary condition comprises an oil tank liquid level and a driving working condition; and based on a preset calculation rule, according to the surface vibration data of the fuel tank shell and the node counterforce of the surface of the shock pad and the bandage mounting point, a fuel shaking noise value is obtained. According to the fuel oil shake noise simulation analysis method and platform and the computer storage medium provided by the invention, the fuel oil shake noise can be quickly and accurately predicted under the condition that the whole vehicle data is not needed, the vehicle research and development efficiency is improved, and the vehicle research and development cost is reduced.

Description

technical field [0001] The invention relates to the field of computer-aided design, in particular to a fuel sloshing noise simulation analysis method, platform and computer storage medium. Background technique [0002] In the field of automobiles, the disgusting sound produced by the car during braking, turning, creeping and other working conditions is generally referred to as fuel sloshing noise. In the prior art, the method of single product verification combined with subjective evaluation is generally used to monitor fuel sloshing noise. If there is fuel sloshing noise, iterative optimization is achieved by continuously changing the structure, but it is often time-consuming and labor-intensive, and the effect is not ideal. Among the existing simulation analysis methods of fuel sloshing noise, some use the radiated sound of the fuel tank shell as the evaluation standard, which is inconsistent with the generation mechanism of fuel sloshing noise, and the reliability of the ...

Problems solved by technology

In the existing technology, single product verification combined with subjective evaluation is generally used to monitor fuel sloshing noise. If there is fuel sloshing noise, iterative optimization is achieved by continuously changing the structure, but it is often time-consuming and laborious, and the effect is not ideal

Among the existing fuel sloshing noise simulation analysis methods, some use the radiation sound of the fuel tank shell as the evaluation standard, which is inconsistent with the mechanism of fuel sloshing noise, and the reliability of the calculation results is poor; while some require complete vehicle data to complete the calculation, but In the early stage of actual vehicle development, it is often difficult to obtain complete vehicle data, which affects the efficiency of vehicle development
