Abstract

The invention discloses a vibration noise test device for an automotive power assembly suspension system. The test device comprises a main cross beam (4), standing columns (5), pedestals (6), an engine suspension fixation beam (1), a gearbox suspension fixation beam (2), and a low tie bar beam (3). Each standing column (5) is connected with one pedestal (6) at the same side. The engine suspensionfixation beam (1) and the gearbox suspension fixation beam (2) are connected to the inner sides of the two standing columns (3) respectively and are provided with an engine suspension connection member (9) and a gearbox suspension connection member (10) respectively. A lower tie bar connecting member (15) is arranged at the low tie bar beam (3). The test device can match suspension parts of different types of automobiles; the main influence paths of the in-vehicle noises can be determined rapidly; the load of the suspension system by the power assembly is measured; and thus targeted optimization can be realized.

Description

technical field [0001] The invention relates to the field of vehicle vibration and noise performance development and powertrain mount system design, in particular to a test device for isolating and researching the vibration and noise of the powertrain mount system of the automobile during the design and development process of the automobile. Background technique [0002] In the process of car design and development, the noise and vibration performance inside the car is one of the important indicators for customers to evaluate the quality of the car. [0003] The noise and vibration in the car is superimposed by multiple excitations arriving at the target position through different transmission paths. In order to better optimize the vibration and noise performance of the vehicle, it is necessary to study the contribution of each excitation and transmission path separately, and to more effectively determine the path where the noise in the vehicle plays a leading role according...
