Transfer Path Analysis

Lab Transfer Path Analysis is a comprehensive solution with tools to predict and assess system noise and vibration response under operational loading as well as determine acting loads from physical prototype testing data. Using this solution, engineers can perform path or modal contribution analysis to determine the root causes of noise issues and optimize noise and vibration behavior. LMS Virtual.Lab Transfer Path Analysis provides a number of estimation methods to calculate loads that reliably represent realistic customer usage. This includes a direct method to compute forces by multiplying displacement difference over a mount by the frequency-dependent mount characteristic. This mountstiffness method is best used when the connecting stiffness is known, which is the case with engine mounts. The solution also includes an inverse method through which loads are estimated from operational responses. This method is used for relatively stiff connections like suspension bushings that show small displacement differences over the connection. Acoustic loads, such as volume accelerations and volume velocities, can be obtained by using operational pressures and acoustical transfer functions as input for the inverse method. Fast modal and FRF-based response prediction solvers and included path and modal contribution assessment tools provide all the functionality to perform root-cause analyses and target-setting exercises. The responses are visualized using a wide variety of NVH-specific post-processing utilities, and can be compared with pre-defined or imported targets.
