Novel multifunctional automobile part noise test platform

Abstract

The invention discloses a novel multifunctional automobile part noise test platform which comprises a main rack and an auxiliary test rack. The main rack comprises a metal bottom plate with wheels. Steel channels are fixed to the metal bottom plate. A steel channel base is movably installed on the steel channels. The two steel channels with openings opposite are fixedly installed on the steel channel base. Each steel channel is provided with a sliding block inside. Each sliding block is used for fixing an article to be tested and fixed to the corresponding steel channel through a bolt. The auxiliary test rack comprises a movable trolley provided with a supporting rod. The supporting rod is provided with a foldable mechanical arm. A test panel is installed at the tail end of the mechanical arm. An iron wire grid plate is installed on the test panel and serves as a reference grid. A test instrument is installed on the back portion of the iron wire grid plate. Under the condition that each noise test use standard is met, the novel multifunctional automobile part noise test platform is low in manufacturing cost and reliable in performance. Automatic data collection and analysis can be achieved on the upper plane, the front plane, the back plane, the left plane and the right plane, the structure is thin and light, and the reflectivity of sound is small.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing and application, in particular, the invention relates to a novel multifunctional noise testing platform for automobile parts. Background technique [0002] With the rapid development of the automobile industry, automobiles have become an indispensable means of transportation in people's lives. According to foreign relevant data, 70% of urban noise comes from traffic noise, and traffic noise mainly refers to vehicle noise. It seriously pollutes the urban environment and affects people's life, work and health. Therefore, noise control is not only related to ride comfort, but also related to environmental protection. However, all noise comes from vibration, which can cause early fatigue damage to some parts of the vehicle, thereby reducing the service life of the vehicle. Excessive noise will not only damage the driver's hearing, but also quickly fatigue the driver, thus posing a ...
