摘要

This paper discusses the use of experimental transfer path analysis (TPA) to find optimized solutions to NVH problems remaining in late vehicle development stages. After a short review of the established TPA methods, a couple of practical cases are discussed to illustrate how TPA, FE models and practical experiments can supplement each other efficiently for finding optimum and attribute-balanced solutions to remaining, complex NVH issues late in the development process. The first example discusses an interesting idle noise and vibration problem for a front-wheel drive car with a pendulum engine suspension and torque rods attached to a resiliently mounted subframe. The second example illustrates the somewhat different approach used for TPA at mid- and high-frequencies. The third example illustrates analysis "shortcuts" that sometimes can save precious calendar time close to SOP, provided that the simplifications are based on qualified, expert judgments. Finally, an example of a tricky, but not unusual transfer path separation situation, when attachments are in close proximity, is discussed and a pragmatic solution approach is proposed.
