How to Reduce Noise and Vibrations from Wind Farms

In the modern age, with our ever-increasing environmental awareness, it’s no wonder that the renewable energy industry is thriving, and in the UK in particular, wind farms. Whilst in its most basic form, wind power has existed since 5000 BC in the form of wind-propelled boats, and the first electricity-generating wind turbine was built in 1887, modern wind power became part of mainstream British society in 1951, and has been flourishing ever since. Due to this prominence, wind power is a keen area of interest to GMT.

The Growing Demand for Improved Railway Technology

The Department of Transport has released a new report stating that Railways have now become the second most-used mode of transport in the UK, second only to cars. This demonstrates that, as roads have become more convoluted, people are making use of the UK’s rail service more and more. This is especially true for those living outside of a city centre but travelling into it for work. Driving into a city during rush hour normally means adding extra time onto your commute. This means that travelling by train can be a much more convenient and appealing option, but only if they are running efficiently. To keep customers happy, trains need to be consistently on time, comfortable, and able to run efficiently during peak times.

The Problem with Worn Suspension Bushes

Suspension bushes are a type of vibration isolator that is often made of rubber. The purpose of a suspension bush is to prevent metal-to-metal contact while still allowing for some movement. The movement is essential for allowing parts of the suspension to move freely. Although small, suspension bushes largely influence the efficiency of a vehicle, playing an important role in the safety, comfort, and handling of a vehicle. Due to the constant exposure to the elements underneath a vehicle, deterioration of suspension bushes can occur over time.

It’s therefore important to check your suspension bushes.
