Romax have worked with the largest and most specialist off-highway industry leaders to support their design and development. Agricultural and off-road projects have included gear box design review, NVH analysis, bearing investigation, bearing condition review, static and dynamic gearbox analysis.
With so much transmission diversity from manual to hybridisation, Romax experts and software can help you drive down your cost whilst increasing the efficiency of the off-highway vehicle as well as improving shift quality.
Funding body: Energy Technologies Institute.
Project partners: Romax Technology (lead), Castrol, ANSYS, Timken.
Duration: 4 years (2012-2016).
Aim: Develop a range of cost-effective technologies to reduce fuel consumption by 2-5% across a range of heavy-duty vehicle applications.
Project outcome: Romax met the project target and significantly reduced parasitic losses by 60%.
Requirement: To model the excavator gearbox using data and drawings provided by the customer and calculate the stress at the planetary carrier, ring gear, and housing stress using static finite element analysis.
Services provided: Romax were able to achieve a good set of results for the planetary carrier and housing which were validated against test measurements with excellent correlation.
Requirement: Romax were asked to undertake virtual modelling of the complete axle including static and dynamic analysis of the axle system, analysis of gear mesh misalignment and planetary gear contact and a comparison of the dynamic analysis results with the customer’s analysis tools and measured test data.
Services provided: This was the first Romax project to analyse the complete axle for an off-road vehicle considering the flexibility of the body structure.
