NVH Transfer Path Analysis Technique

Year:
2008
Category:
Other categories technology
Technique Features:

1.Estimating Effective input force quantification for each transfer path.
2.EstimatingTransfer path contribution and critical path identification.
3.Estimating Relative contribution of input force and structural sensitivity for concerned issue.
4.EstimatingCan be exported to CAE for rapid strategy iteration.
5.Integrating with CAE to evaluate the improvement result rapidly.

Specification:

1.Data acquisition system and spectrum analyzer are provided.
2.Powertrain TPA frequency range:0-2000 Hz.
3.Road TPA frequency range:0-500 Hz.

Applications:

NVH development and verification of Vehicle, Motorcycle and ATV.

Benefit:

TPA model could be rapidly constructed to define NVH problem and be applied in trouble shooting and solve the NVH problems. This technique can be also integrated with CAE for virtual testing and product optimization. The database established by various types of TPA can help to define the NVH target.
