GRM is a design engineering consultancy, providing product, analysis and software solutions. Within its core is the development and application of design optimisation methodologies to solve complex engineering problems in the most efficient, cost effective way.
GRM works in a number of industrial sectors, including rail. They had been commissioned to do some design work for a new train arm rest and were having issues with an element of the design for that product. The friction assembly for the train seat arm had been noted to cause excessive wear on the internal surface with evidence of wear debris following limited cycling of the assembly. They were unsure how to go about resolving this issue for further iterations of the product.
We were delighted to help GRM with this project. Investing in the sorts of testing capabilities and equipment that we have at WMG is not an option for most SMEs and so being able to support them to validate materials and products through our funded programme is a vital support

Through an existing contact at the WMG centre High Value Manufacturing Catapult, Engineering Manager, Oliver Tomlin was made aware of the WMG SME Group and the work they were doing to support the manufacturing supply chain via Innovate UK funds. He met with the materials specialists including Dr Paul Milne and Dr Kylash Makenji and they designed a testing regime that would help to resolve the issue. They were able to assess the reason for the high wear rate of the train seat arm using optical microscopy and to identify the materials used in the manufacture of the components to improve the condition.
This optical microscopy work has led to a resolution for the assembly of components that GRM can incorporate into a new design. By looking at alternative assembly options and by confirming the properties of the material , there is now the potential for new products to be developed in the sector and further work for GRM on future rail projects.
