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 present invention relates to the technical field of automobile manufacturing applications. Specifically, the present invention relates to a new type of multifunctional automobile parts noise test bench. 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 relevant foreign 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 lives, work and health. Therefore, noise control is not only related to riding comfort, but also related to environmental protection. However, all noise comes from vibration, which can cause early fatigue damage to certain parts of the vehicle, thereby reducing the service life of the vehicle. Excessive noise will not only damage the driver's hearing, but also make the driver fatigue quickly, ...

Embodiment Construction

[0024] In order to make the above objectives, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] The design idea of ​​the present invention is:

[0026] Design a new type of auto parts new multifunctional auto parts noise test bench, the bench is divided into two parts: main bench and auxiliary test bench.

[0027] The main stand is mainly used to install the tested products, such as engines, transmissions, vehicle motors, etc. The stand is installed on a heavy metal base plate with multiple support legs fixed by suction cups to improve product testing time The stability of the whole system will not cause the platform to shift or self-resonate due to vibration. Design a unique structure according to the two positions of the metal plate and the bottom:

[0028] 1. The upper part of the metal plate is designed with...
