Acoustic simulation technology involves almost all engineering fields. The reason is simple: no industry can allow noise or substandard sound Product.

ActranAssist the transportation, aerospace and defense, machinery and consumer goods industries in meeting increasingly stringent noise regulations, or ensure that new designs are consistent with the company's acoustic trademark.

With rich modeling capabilities and high-performance solvers, engineers can deal with noise caused by acoustics, vibration, or flow in a limited amount of time Voice challenge. User friendly and highly customizable graphical user interface ensures reliable and cost-effective integration of acoustic simulation into any industrial flow During the journey.

Typical applications:

• Noise prediction of powertrain, gearbox, and electric engine

• Acoustic characteristics of engine intake and exhaust systems

• Pneumatic of rearview mirror and air conditioning environmental control system-Vibration-noise analysis

• Tire and noise assessment, including acoustic treatment optimization

• Acoustic comfort inside the vehicle, including the full interior bodyNVHPerformance evaluation and acoustic package optimization

• Prediction of acoustic transmission loss in multi-layer structures, considering frequency variation Acoustic treatment effect of transformation

• Comparison of Transmission Path Analysis and Design Change Impact

• Consider the installation effect (structural vibration, sound absorption, etc.) of the fan Noise assessment

• Integrated performance evaluation of audio equipment

• Acoustic treatment of aircraft intake and exhaust noise and optimization of cabin design

• Prediction of the propagation of aerodynamic noise in the aircraft body

• Underwater noise propagation

• Prediction of vibration induced acoustic fatigue caused by high-intensity random acoustic loads and vibrations
