Carbon Fiber Parts Assist Enhance Power Consumption on Excessive-speed Trains


Share post:


Talgo was in a position to take away 50% of the load of the operating gear frames for high-speed trains by utilizing carbon fiber strengthened polymer (CFRP) composites. The discount within the tare weight of the practice improves the power consumption of the practice and due to this fact the passenger capability amongst different advantages.  

Working gear frames, often known as rodals, are the second heaviest structural element of a high-speed practice and have strict structural resistance necessities. Conventional operating gear frames are product of welded metal plates and are topic to fatigue due to the geometry and the welding course of. The staff at Talgo noticed a possibility to switch the metal operating gear frames and studied quite a few supplies and processes, discovering that carbon fiber strengthened polymers had been the best choice. Talgo efficiently accomplished full-scale validation of structural necessities, together with static and fatigue checks, in addition to non-destructive testing (NDT) testing. Fireplace-Smoke-Toxicity (FST) requirements had been met thanks at hand lay-up of the CFRP prepreg. Weight discount is one other clear profit to using CFRP supplies. 

The CFRP operating gear frames had been developed for the Avril high-speed practice. Subsequent steps for Talgo embody working the rodal beneath actual situations for remaining approval in addition to increasing growth for different commuter autos. The brand new elements will result in diminished power consumption and fewer put on and tear on the tracks due to the lighter weight of the practice.
