Introduction
Use the Adams Acoustics plugin to understand how the cooler housing will vibrate during normal operation and calculate sound pressure levels.
■A frequency-domain acoustic analysis can be performed and reviewed based on an Adams model's time-domain analysis
■The user does not necessarily have to be an acoustics specialist. A system specialist (Adams user) can run the analysis as the interface in Adams provides a full set of default values for the required Actran acoustic parameters.
■Nevertheless, acoustics specialists can improve the simulation by adapting the default input values
■One single model to get an insight in acoustics behavior, even in early design stages
Model Description
■The model represents a cooler mechanism including a gearbox
■The input shaft rotates dues to an applied torque
■The gearbox will increase rotational speed from the input shaft to the cooler rotor shaft
■The gearbox will introduce vibrations into the system
■The cooler housing is represented as a flexible body, allowing it to vibrate
Process
Step is done by the user, standard procedure to generate a flexible body for Adams (this is already done for this exercise). Steps are automated, executing Actran in the background.
