Case Study: Seismic Assessment of a Structure to EC3

"This is the second major project for which we have engaged Ramsay Maunder Associates. Both instances have involved the structural verification of seismic rated battery racks supporting essential supplies batteries. In both cases we have found their professional attitude and diligence exemplary. From the initial modelling through to reporting and follow up technical queries their work was second to none. I would not hesitate to recommend their services to anyone seeking such services."

Project Type: Design Analysis Service
Engineering Discipline: Mechanical

John Harvey are developing a new 700 litre water tank for the watering of pigs. The tank is made from plastic and needs to be carefully designed to avoid excessive bulging from the hydrostatic loading. RMA have been employed to assess the tank design and advise on the required wall thickness.

Case Study: Design/Analysis of a Pair of Pulley Wheels
Testimonial: Matthew Gee, Design Engineer, Stenner Ltd

Stenner manufacture industrial bandsaws for the commercial timber industry. RMA were employed to assist in the design and analysis of the main pulleys for an upgraded machine running at a higher speed. The work involved finite element analysis to determine the elastic stresses around stress concentration features in order to make a fatigue life assessment. Additional analyses were conducted to confirm the burst speed and the natural frequencies of the pulleys.

Project Type: Failure Analysis
Engineering Discipline: Mechanical

RMA assisted Peter Brotherhood in the finite element analysis of a steam turbine component to aid understanding of a structural failure. This work led to a realisation that the ASME coefficients of thermal expansion are not listed to an adequate precision for useful engineering calculations.

Project Type: Failure Analysis
Engineering Discipline: Mechanical
Case Study: Fatigue Assessment of a Machine Component

RMA worked with Sibelco on a failure analysis problem in the understanding of premature component failure in a clay processing machine at their Newton Abbot site. The analysis work undertaken by RMA revealed a likely reason for the fatigue failure and design modifications to the component have been made.

Case Study: Seismic Assessment of a Structure to EC3
Testimonial: Russell Shaw, Managing Director, Nirvana Engineering (Stafford) Ltd

Nirvana Engineering designs and manufactures steel structures used in the reserve power industry. Such structures often need to be seismically qualified to ensure that they remain functional in the event of an earthquake. RMA recently conducted such an assessment of two steel structures for Nirvana Engineering. These were analysed using both the Equivalent Static and the Response Spectrum methods in the ANSYS finite element system (ANSYS) and assessed according to the Limit State Design code EC3.

Project Type: Design Analysis Service (On-Site)
Engineering Discipline: Structural

RMA supplied a Security Cleared engineer to provide on-site consultancy at SCX for the structural analysis of a static crane for the AWE Mensa project. The project, which involved static and seismic loading, was the first FEA work undertaken at SCX and detailed verification work was therefore undertaken and a full technical report provided to the client.
