Secondary Suspension. Within the secondary suspension between the bogie and the vehicle body, our air spring systems provide for the flexible mounting of the vehicle body. Air springs have a low natural frequency, which minimizes the transmission of vibrations. They decouple it from the majority of track irregularities, while also allowing the

Enclosed pressurized air in a predefined chamber called air spring, provides various suspension characteristics including damping.

railways to a bogie vehicle brought with it a more sophisticated suspension system. This system was based on a steel plate framed bogie with laminated spring axlebox suspension, much as seen on the first vehicles, and with a secondary suspension added between the car body and the bogie. First, we look at the primary suspension.

The bolster beam is attached to the bogie frame by the secondary suspension unit. The primary suspension is provided between axle and bogie frame. The primary suspension consists of a control arm, a set of steel coil springs and a vertical hydraulic damper at each wheel, i.e. 4 sets per bogie.

Primary suspension consists of primary spring and damper. Control arm connecting axle guide to bogie frame is also designed to mimic the actual dynamic behaviour of bogie. Bolster is connected to bogie through secondary suspension. It consists of secondary springs, vertical damper, lateral damper, yaw damper, bump stop and anti-roll bar.

FIAT Bogie. by Pradeep Gupta - January 21, 2023. The FIAT Bogie is a bogie used in LHB Coach. It is an adoption of EUROFIMA design. The FIAT Bogie is a two-axle type, with a primary and a secondary suspension, and with an axle mounted disc brake system. FIAT Bogie.

Primary suspension system of these bogies includes primary springs, hydraulic dampers, bump stops and control arms. Multiple cases of spring failures in primary suspension systems, have been reported during the last two years, mainly in LWSCN, LGS, buffet and power cars [3]. Actual images of such a failed spring are shown in Fig. 1.

This presentation summarizes the design aspects of ICF type LHB hybrid bogies. Key features include rigidly guided axles to maintain parallelism, double row spherical roller bearings to provide low rolling resistance, and least unsprung mass to reduce wear. A two stage suspension with shock absorbers and an air spring on the secondary suspension provide isolation from vibrations. Other

The primary and secondary suspension systems are modelled as Combination14 elements in the FE Model of the Bogie in ANSYS. FE mesh of the bogie consists 3,80,217 nodes and 2,14,545 elements.

The Primary and Secondary suspension systems and various dampers used in FE analysis are modelled as spring and damper elements respectively. In this work, free vibration analysis or modal analysis of the FIAT railway bogie is carried out to extract the first few modes of vibration. The Natural frequencies obtained along with the corresponding

Hydraulic shock absorbers with capacity of ±600 kg at a speed of 10 cm/sec. are fitted to work in parallel with the bolster springs to provide damping for vertical oscillations. The main components of secondary suspension are: Bogie bolster upper plank. Bogie bolster lower plank. Suspension link, link pin & stone.
