Global trade pattern recognition

Subway engine (is the subway engine too loud?Global trade pattern recognition Try these methods!)The subway is one of the most convenient and fastest means of transportation in the city, but when using the subway, we often encounter a common problem: the subway engine is too loud. The noise of subway engines not only affects the comfort of passengers, but also affects the urban environment and the health of residents. In order to solve this problem, we can take some ways to reduce the noise of the subway engine. 1. Strengthening sound insulation is the main way to reduce the noise of subway engines at present. The sound insulation layer between the carriages and the car body of subway vehicles can reduce the spread and diffusion of noise. Improving the sound insulation performance of subway vehicles can effectively reduce engine noise, thus improving the comfort of passengers. In addition, track wetting technology can also be used to reduce the friction noise between the subway wheels and the track, further reducing the noise level of the whole subway.Two. The noise of replacing more advanced engines and shock absorbers subway engines mainly comes from vibration and friction. Therefore, while soundproofing, upgrading more advanced engines and shock absorbers is also an important means to reduce noise. Adopting a more efficient and environmentally friendly engine can reduce its noise level, and the improvement of shock absorbers can also reduce vibration and noise generation. 3. Adjusting the operating speed and frequent acceleration and deceleration of the route is also one of the reasons for the high noise of the subway engine. Therefore, the noise of the subway engine can be effectively reduced by adjusting the operating speed and route. During peak hours on weekdays, the subway should slow down appropriately to avoid increased noise caused by excessive speeds. During low peak hours, the subway can run faster to improve operating efficiency and reduce the waiting time of passengers, thus making the subway more convenient and comfortable.Four. One of the reasons for the increase in the noise of the subway engine is caused by damage or excessive wear of the equipment of the vehicle. Therefore, regular maintenance and maintenance of subway equipment and timely replacement of worn parts can reduce the noise of subway engines and improve the operation efficiency and safety of subway vehicles. 5. The progress of adopting new technologies and technology has also brought new opportunities to solve the noise problem of subway engines. Existing new technologies, for example, replacing traditional internal combustion engine engines with electric engines, can greatly reduce noise and improve the environmental protection of the subway. In addition, track compensation technology can also be adopted, which can reduce the noise from the friction between the wheels and the track and effectively reduce the noise level of the subway. In a word, reducing the noise of subway engines is an inevitable trend for cities to promote the development of green and intelligent transportation.We should constantly innovate and improve in technology, equipment, maintenance and other aspects, and seek further improvement and improvement in actively exploring solutions and comprehensively improving the service level and comfort of urban subway transportation. Only in this way can we make the subway move faster to a better and more comfortable future!
