WORLDWIDE R&D
All the research and development for the Lucchini RS Group is performed in Italy. Our design solutions have been defined according to the relevant national and international standards and have often gone beyond such already strict requirements.

FOCUS AND COMPLIANCE
DESIGNING POSSIBILITIES
RESILIENT WHEEL
Our resilient wheel has been optimized to resist wear and tear, improving Light Rail Vehicle safety and the Total Life Cycle Cost. Consisting of basic components such as a tyre, a wheel centre, a retaining ring and rubber rings/blocks, it can withstand increasing axle loads and can also easily accommodate the noise absorbing Syope® system.
LimoSet® innovative portal axle design for low floor LRVs has addressed two distinct objectives: reduction of the Total Life Cycle Cost of the wheelset and introduction of modularity concept that grants easy assembly, disassembly and inspection, and lower maintenance costs for the operators. Designed for urban application, it is lighter than the existing solutions.
Thermostable (i.e. “low-stress”) wheels designed to limit deformations and internal stresses caused by thermal loads during tread braking.
TESTING PERFORMANCE
Lucchini RS has invested in technology and innovation from the beginning, now boasting one of the world’s largest, most advanced, and complete train wheel and axle accredited testing facilities. All of the Lucchini RS products and solutions are tested, improved, and scientifically validated to target industry-specific challenges. Cutting-edge equipment and impartial, independent, and knowledgeable staff allow the laboratories to perform metallurgical and metallographic tests, chemical and environmental analyses, as well as mechanical, fracture, fatigue, dilatometric, and corrosion tests of wheelsets, axles, wheels.
In the R&D Laboratory fatigue and stress tests, on full scale wheelset components from normal series production, are carried out to validate and qualify the product and production process. The laboratory is equipped with 2 resonance test benches able to perform fatigue test (up to 25Hz) on wheels and axles according to relevant standards and other test benches mainly used for research activities (wear, crack propagation, RCF, etc.). The superior quality of the service offered by Lucchini RS laboratories is recognized and guaranteed by ACCREDIA, which certifies conformance with the requirements of UNI CEI EN ISO/IEC 17025 in carrying out the accredited tests.

DESIGN SERVICE
BETTER DESIGN FOR EFFECTIVE NON-DESTRUCTIVE TESTING
Lucchini RS axles are designed according to EN standards, but also consider the effect of crack propagation using StarCrack software, developed and validated over the years by full-scale tests on our test rig. This calculation method makes it possible to correctly simulate real service conditions for the entire service life of the axle and to define precise inspection intervals.
MASS OPTIMIZATION DESIGN
The reduction of unsprung masses equals an increase in vehicle payload. This also helps reduce vehicle damage, energy consumption and total operating costs.
