Metal sound barrier with monitoring function

Abstract

The invention discloses a metal sound barrier with a monitoring function. The metal sound barrier comprises an aluminum alloy ribbed back plate, an aluminum alloy punched panel and multiple force transducers. The aluminum alloy ribbed back plate is fixed to the aluminum alloy panel through an aluminum alloy frame, and the force transducers are arranged in the center regions of the inner sides of the aluminum alloy ribbed back plate and the aluminum alloy punched panel, and transmit signals to a computer terminal. According to the metal sound barrier with the monitoring function, the panel andthe back plate can be subjected to force measuring monitoring in real time, so that the purpose of knowing the health state of the sound barrier at any time is achieved, the force bearing state of themetal sound barrier is monitored in real time, the problems such as looseness can be judged at first time, the advantages that dynamic testing can be carried out, testing automation and remote monitoring can be achieved, the testing precision is high, the structure is simple, and processing and manufacturing are convenient are achieved, and certain theoretical guiding significance can be achievedfor the fatigue life of a sound barrier system.

Description

technical field [0001] The invention relates to the technical field of vibration and noise control, in particular to a metal sound barrier with a monitoring function. Background technique [0002] In recent years, the country has proposed new policies such as the Belt and Road Initiative and the high-speed rail economic circle, making high-speed rail a business card for China to the world, which shows that the country attaches great importance to the high-speed rail industry. In this context, in recent years, my country's high-speed rail industry has developed rapidly. However, in the process of increasing train speed, environmental noise pollution and other problems have become increasingly prominent. The sound barrier is one of the important measures to absorb and reduce railway noise, but because the sound barrier is close to the railway, the pulse load generated when the train passes by acts on the sound barrier panel and back plate, causing the sound barrier to vibrate....

AI Technical Summary

Problems solved by technology

The sound barrier is one of the important measures to absorb and reduce railway noise, but because the sound barrier is close to the railway, the pulse load generated when the train passes by acts on the sound barrier panel and back plate, causing the sound barrier to vibrate. When the sound barrier is used, its main components may become loose, which becomes one of the important hidden dangers of locomotive driving safety.

At present, the understanding of the health status of the sound barrier basically depends on the naked eye recognition when the train passes by. The loosening of the sound barrier is not obvious without air flow disturbance, and the health status of the sound barrier cannot be known at any time.
