Railway Part Train Damping Spring

Introduction of Train Damping Spring

Train damping spring is an energy conversion device, which converts the intense kinetic energy generated during train operation into controllable heat energy release through elastic deformation. Its core performance is reflected in three dimensions: first, the dynamic load bearing capacity, a single set of spring systems can instantaneously withstand up to 200 tons of impact load; The second is the frequency response characteristic, the multi-stage progressive stiffness design, in the vibration range of 0.5-30Hz to maintain more than 85% of the energy absorption efficiency; Finally, the phase adjustment function, through the specially designed spiral Angle, the longitudinal vibration and the transverse swing to form a phase difference, effectively resolve the superposition effect of complex vibration.

Function of Train Damping Spring

Train damping spring is an energy conversion device, which converts the intense kinetic energy generated during train operation into controllable heat energy release through elastic deformation.

Design of Modern Shock Absorber Spring System

Design of Modern shock absorber spring system adopts modular design, each unit contains the main spring, limiter, damping valve three components. The main spring is made of chromium-vanadium alloy steel as a whole. After special heat treatment, the hardness standard of HRC52-55 is reached. With the surface nitriding process, the elastic modulus can be kept stable at extreme temperatures from -40℃ to 120℃. The limiter has a nonlinear stiffness design, and its stiffness coefficient increases exponentially when the amplitude exceeds the safety threshold, ensuring system integrity under sudden impact. The damping valve has an intelligent adjustment system, which automatically adjusts the oil flow through real-time monitoring of axle load changes, so that the damping system is always in the optimal working state.

Multi-dimensional Applications of Train Damping Spring

For different operational needs, modern shock absorbing springs have been developed to travel differentiation technology routes: freight trains use high-stiffness spring groups, through the parallel structure to achieve 130% overload protection; Urban rail vehicles are equipped with low-frequency vibration suppression system to deal with resonance caused by frequent start-stop. The high altitude EMU is equipped with air pressure compensation device to eliminate the influence of altitude change on spring stiffness. In the newly developed magnetorheological spring system, the damping coefficient can be adjusted in real time by changing the magnetic field intensity, which lays a technical foundation for the next generation of intelligent rail vehicles
