Machine Vibration Causes and Fixes

April 6th, 2023 by

What Is Machine Vibration?

Most machinery experiences a level of vibration, and will have an expected ‘normal’ range of machine vibration while functioning. However, over time, or if something breaks or goes wrong, this level of vibration may be elevated beyond what is expected, and this can easily become dangerous to operators and the machine itself.

5 Signs You Need to Replace Worn Engine Mounts

June 2nd, 2021 by

An engine mount’s primary purpose is to secure an engine into machinery and absorb any shocks and vibrations when the machinery is operating. Engine mounts and anti-vibration mounts are essential for preventing damage to the engine and improving operator comfort (where applicable). But what happens when engine mounts need replacing? And, do you know the symptoms of worn engine mounts? We answer both of these questions in this post.

An Introduction to Anti-vibration and Vibration Control Electric Car Components

March 12th, 2020 by

Originally, in July 2017 the government announced a ban on the sale of any new diesel, petrol or hybrid cars by 2040, in an effort to dramatically reduce air pollution. This comes as a strand of a larger plan to attempt to emit zero carbon by 2050. As such, as of February 2020, the banning of petrol and diesel cars by 2040 was brought forward to 2035 “if possible“.

A Short Guide on the Storage of Rubber and Rubber to Metal Components

August 8th, 2019 by

Many properties of rubber make it the ideal material for anti-vibration products. To conserve these properties it’s important that the rubber is protected from environmental conditions, such as light and heat, that might otherwise degrade it. Consideration should also be given to protecting the metal that the rubber is often bonded to, as this can also be affected by these conditions.

The Growing Demand for Improved Railway Technology

September 24th, 2018 by

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

January 17th, 2018 by

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.

What is 3D Modelling?

June 27th, 2017 by

How We Use 3D Modelling

Special software allows us to plan out and accurately represent the object we have in mind. Connecting geometric shapes, curved surfaces, and lines, the 3D model gives a mathematical description of the surface of the object. Here at GMT Rubber, if standard products are not suitable to a client, we are able to produce a new design using 3D modelling. This is used in conjunction with Finite Element Analysis (FEA).

With knowledge of the client’s needs, we build a product to meet the specification whilst ensuring that the finished design is also capable of meeting service life/durability requirements.
