Noise Prediction Moving Mechanisms Coupled Multibody Dynamics Acoustics Analysis

It is generally difficult to predict the noises coming from a transmission system or gearbox. One, there are complicated moving mechanisms inside the system, and different ways in which the parts interact with each other causing varying contact forces and vibrations. Two, understanding how the dynamic performance can influence the radiated acoustic waves is also a big challenge. Without the ability to accurately predict how the system dynamics will impact its noise performance, engineers don’t have an efficient method to redesign their systems to improve acoustic behavior. What is needed is a highly integrated Multibody Dynamics-Acoustics solution to cope with this type of problem, and that’s where the new Adams-Actran integration solution can be applied to help engineers. Watch this video and learn more about two different methods to couple Adams (multibody dynamics (MBD)) and Actran. (acoustics)
