Problems solved by technology

However, in the actual implementation, when engineers optimize the design of the controlled system and components, they cannot timely confirm which part of the controlled system or components affects the ride comfort, and often require a large number of theoretical calculations and multi-body analysis As well as real vehicle tests, etc., not only increase the additional economic expenditure, but also have a long response cycle, and at the same time, due to various objective reasons, there may be inconsistent results, which will affect the judgment

Embodiment Construction

[0042] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0043] Embodiments of the present invention provide a vehicle ride comfort analysis method, referring to figure 1 , figure 1 It is a schematic flowchart of the first embodiment of the vehicle ride comfort analysis method of the present invention.

[0044] In this embodiment, the vehicle ride comfort analysis method includes the following steps:

[0045] Step S10: Obtain the vehicle parameters of the vehicle to be analyzed;

[0046] It is easy to understand that vehicle parameters can be understood as parameters that can be used for vehicle ride comfort analysis, including but not limited to sprung mass M s , unsprung mass M u , spring stiffness K s , tire stiffness K t , shock absorber damping C s and the impact load f, where the sprung mass M s , also known as the sprung mass, can be understood as the mass carr...

Abstract

The invention relates to the technical field of vehicles, and discloses a vehicle smoothness analysis method, device and apparatus and a storage medium, and the method comprises the steps: obtaining the whole vehicle parameters of a to-be-analyzed vehicle; inputting the whole vehicle parameters into a pre-constructed vehicle smoothness analysis model for online smoothness analysis so as to obtain smoothness parameters, wherein the vehicle smoothness analysis model is established based on a sprung mass mechanical relational expression and an unsprung mass mechanical relational expression of a vehicle body; and determining a ride comfort analysis result of the to-be-analyzed vehicle according to the ride comfort parameters. The vehicle smoothness analysis result of the to-be-analyzed vehicle can be quickly obtained only by inputting the whole vehicle parameters of the to-be-analyzed vehicle into the vehicle smoothness analysis model for online smoothness analysis, so that the vehicle smoothness analysis speed is increased, the vehicle smoothness analysis is conveniently and quickly performed. And the popularity rate and the intelligent degree of vehicle smoothness analysis are also improved.

Description

technical field [0001] The present invention relates to the technical field of vehicles, in particular to a vehicle ride comfort analysis method, device, equipment and storage medium. Background technique [0002] Vehicle ride comfort refers to the performance of the vehicle to resist the vibration and shock generated during driving. It is one of the main indicators of vehicle comfort. Therefore, in vehicle design, especially in suspension design, the primary task is to ensure that the vehicle has good ride comfort. [0003] In the prior art, the main parameters used to measure the ride comfort of the vehicle are mostly obtained through complex theoretical analysis, multi-body dynamics analysis and real vehicle testing. However, in the actual implementation, when engineers optimize the design of the controlled system and components, they cannot timely confirm which part of the controlled system or components affects the ride comfort, and often require a large number of the...
