Vehicle Road Noise Simulation
Road noise NVH simulation relies on high-precision full-vehicle finite element models, adopts measured real road surface spectrum as excitation load, and performs computational analysis via professional simulation software. It identifies the generation sources and transmission paths of vibration and noise during vehicle operation, as well as interior vibro-acoustic responses and their impacts on occupants. Based on the simulation results, targeted optimization can be implemented on components including chassis structure, suspension bushing stiffness and body structure, which effectively reduces road noise and road-induced vibration while further improving vehicle ride comfort.
Vehicle Road Noise Simulation
Product Overview

In recent years, consumer demand for new energy vehicles (NEVs) has kept rising steadily. Without the masking noise from conventional internal combustion engines, road noise issues of NEVs become far more prominent.

 

Landtop Technology can carry out precise road noise simulation analysis at the digital development stage to detect hidden risks in advance and deliver complete optimization schemes, eliminating road noise defects at the design source. After entering the physical vehicle tuning phase, road noise simulation enables rapid root cause identification and pinpointing of problematic locations, together with practical engineering rectification proposals for implementation.

 

Up to now, Landtop Technology has provided one-stop full-vehicle NVH road noise simulation solutions for numerous mainstream OEMs including SERES, BAIC, JAC, Chery, SAIC and more.



Application Area

■ Passenger Vehicles: SUVs, Sedans, MPVs

Structural NVH Simulation
Structural NVH Simulation
The vehicle body serves as the core response system of the full-vehicle NVH system, and its inherent vibration and noise response characteristics directly determine the overall NVH performance of the complete vehicle. Conducting vehicle NVH performance analysis and optimization in the virtual R&D phase via structural NVH simulation can largely avoid NVH risks triggered by unreasonable body structure design. This drastically cuts down engineering changes and test verification workload in the later stage, and effectively saves various R&D costs including prototype manufacturing, test equipment and labor expenses.
