Aim: Develop a range of cost-effective technologies to reduce fuel consumption by 2-5% across a range of heavy-duty vehicle applications.
Investigate efficient gear and bearing designs to reduce axle power losses,
Test the new technologies at component and system level.
Project outcome: Romax met the project target and significantly reduced parasitic losses by 60%.
Romax can supply expert engineering services and software to satisfy a number of requirements including:
Design – system design to improve reliability, durability and performance
Analysis – predict system and bearing behaviour under misuse or other conditions, forecast life, identify sources of system noise and improve NVH performance
Testing – advice and support on testing programmes, virtual testing for extreme load conditions
Problem solving – improve NVH and gear shift performance
Case study in Excavator Gearbox Static Analysis
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.
Case study in Fork Lift Drive Axle NVH Analysis
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.
