Acoustics

RecurDyn/Acoustics is a noise analysis toolkit that calculates the Equivalent Radiated Power (ERP), which represents the noise characteristics, based on the MFBD analysis results. Through the distribution of calculated ERP, it is now possible to perform the predictive analysis for noise of the mechanical system by confirming which parts of the surface of a flexible body emit more noise and which frequency band ERP is dominant.

  Features in Acoustics

Key features of Acoustics toolkit

• Calculates the ERP for the defined PatchSet using the analysis results of an MFBD model.
• Ability to simulate noise characteristics of the system with minimum parameter input
• Ability to calculate the defined time domain for more efficient post-processing
• ERP results can be displayed on the surface of a flexible body as a contour during animation.
• ERP results can be viewed using various types of graphs through the Scope dialog.

Co-simulation between flexible bodies and particles

Flexible bodies in RecurDyn can now be used for co-simulation with EDEM or Particleworks. When defining a Wall, it is now possible to select not only a rigid body but also a flexible body, which enables the co-simulation between flexible bodies and particles. It is now possible to perform dynamic analysis considering the interaction of flexible bodies with fluid flow. (both FFlex and RFlex bodies are supported.)

Co-simulation between assembly and particles

The bodies created using the Assembly function in Belt, Chain, Track LM, Track HM can also be defined as a Wall (vessel) and used for the co-simulation with EDEM or Particleworks. In this case, you can select an individual body belonging to an assembly and define it as a Wall, or you can select an assembly itself and define all of its bodies as a Wall.

General CoSim

Newly added functions of General CoSim enable simultaneous co-simulation with multiple software that support FMI. In this case, the Master should be RecurDyn and the software supporting FMI (AMESim, SimulationX, Simulink, etc.) should be defined as the Slave. Co-simulation between multiple Slaves and RecurDyn is now possible.

For example, after modeling a controller using Simulink and a hydraulic actuator using AMESim, it is now possible to co-simulate between them and a RecurDyn model simultaneously.
