In short, the development mode of the adaptability of the vehicle to water is provided.

With the continuous departure of various national standards, the related requirements of waterproof and the like of the whole vehicle are further strengthened to improve the safety of the vehicle, and the water management performance of the vehicle, which is one of the most perceivable performances of a user, is more and more emphasized by vehicle enterprises, and is now one of the key performance indexes in the development of the whole vehicle. In order to avoid serious quality perception problems such as water management and the like of an automobile under the working conditions of rain, vehicle washing, wading, rain fog and the like, the development capacity of the water management of the automobile needs to be improved through early-stage design control, and the related technical difficulties of the water management are overcome. In the manufacturing process, the production process is controlled, the quality of parts or systems is improved, and the market vehicles are guaranteed not to have corresponding water management quality problems through reasonable and scientific product development.

In the prior art, the interaction between the vehicle and water and dust is often analyzed through CFD simulation, the behavior of the vehicle in a severe environment is predicted, and the driving safety and the vehicle reliability are improved. The simulation of CFD (Computational Fluid Dynamics) in vehicle water management mainly includes vehicle wading, a-pillar flooding, rain analysis, and vehicle body contamination.

The whole vehicle wading analysis mainly researches whether risks such as water inlet of an engine air inlet, electric short circuit, water seepage of a firewall and the like exist after an automobile drives through a water pit with a certain depth at a certain speed. With the development of automobile electrification, more and more electric elements including battery packs and the like are arranged on a chassis of an automobile body, and if a short circuit problem occurs in the wading process of the whole automobile, the running of the automobile is influenced, and the safety of drivers and passengers can be endangered.

The A column overflow mainly researches the influence of rainwater overflowing to the side window through the A column to the side window visual field after the rainwater forms a liquid film on the front windshield. Rain analysis and analysis mainly pay attention to whether the drainage capacity of the drainage groove is enough after the automobile is drenched with rain, whether the risk of submerging an air inlet of an air conditioner or sucking rainwater into the air inlet of the air conditioner exists, and whether sensitive electric devices such as a wiper motor and the like have a soaking risk is paid attention to. The pollution of the automobile body mainly focuses on the dust accumulation on the surface of the automobile body caused by the splashing of the wheels, the pollution of a rear window caused by the wake vortex of the automobile and the like. Since water management involves multiphase flow and transient analysis, conventional CFD software is typically very slow to compute when analyzing. Using STARCCM + for a round of wading analysis, Computing on a High Performance Computing (HPC) may also take from one to two weeks. The Powerflow and SPH (smooth Particle Hydrodynamics) methods using LBM (Lattice Boltzmann Method) methods, pionlab, have great advantages in computation time, and can shorten the simulation time to about one day.

In the actual development process, the simulation application of the water management of the whole vehicle also participates in specific projects to a certain extent, for example, the A column overflow analysis can be carried out at the early stage of modeling, and some requirements are provided for modeling development. After the data of the whole vehicle is published, the wading analysis of the whole vehicle can be carried out, the wading risk can be checked, and some requirements can be provided for the arrangement of the whole vehicle. Rain analysis may also provide some guidance regarding the placement of the gutter.
