A Comprehensive Overview of the Static Test Bench for Bogies
Accuracy and reliability are of the utmost importance in railway repair and inspection. The static test bench for bogies is a vital tool designed to ensure the uniformity and safety of the carriages used in railway vehicles. These tools are critical for performing static load tests and measuring parameters necessary to ensure proper operation and efficiency of the bogies.
Essential Functions of a Static Test Bench for Bogie
The purpose of the static test bench for bogie is to perform comprehensive measurements and test static pressure on various bogies, such as magnetic rail brake bogies, swing bogies, radial bogies and two-axle EMUs. Some measurements include axle spacing, parallelism, wheel inside distance, wheel-rail load, wheel weight variations, and bogie height. These comprehensive tests depend on maintaining the efficiency and security of railroad passenger vehicles.
The 50-ton and 70-ton are the two main variants of bogie static test benches that are available. To accommodate different testing requirements, each model has its own special features and technical specs.
Detailed Specifications of the 70-Ton Static Test Bench
The 70-ton bogie static test bench is designed for heavy-duty testing and has a range of advanced features. With a maximum height of 4 meters, larger bogies can be accommodated. It can support a maximum load force of 70 tons and has a width of 3.7 meters. This bench's 300-millimeter load itinerary offers a sufficient range for various testing situations. It is compatible with multiple gauges, including 1067 mm, 1435 mm and 1676 mm.
The bench weighs 15 tons and can handle wheelbases ranging from 2000 to 3000 millimeters. It supports two axes and accommodates wheel widths between 90 and 140 millimeters. The wheel edge height ranges from 19 to 38 millimeters, while the wheel load varies from 150 to 250 kilonewtons. Custom specifications are available for the height of the bogie and the length of the turn frame. The test cylinder spacing ranges from 500 to 3000 millimeters. This model is made to function in the 5°C to 35°C ambient temperature range guaranteeing consistent operation under diverse climatic circumstances.
Technical Features of the 50-Ton Static Test Bench
The 50-ton static test bench offers precise measurement and testing capabilities. With a gauge of 1435 mm, it has two separate vertical loading units. This equipment uses an AC three-phase power supply with a frequency of 50Hz and a voltage of 380V (±10%). The hydraulic loading mechanism has an accuracy of ±100 newtons and a force range of 0-250 kilonewtons. The loading force position adjustment range is 20 to 3000 millimeters with a positioning accuracy of ±0.3 millimeters and the loading cylinder synchronization error is within ±0.2 millimeters.
The pressure sensor used in this bench is rated at Level 4, and the height difference measurement accuracy between cells is ±0.5 millimeters. Wheel-to-medial distance precision is ≤±0.2 millimeters and the axis diagonal measurement accuracy is ≤±0.2 millimeters. The wheelbase measurement range is from 1800 to 3000 millimeters, with a precision of ±0.2 millimeters. The measurement error for the four-corner height of the bogie is ≤±0.15 millimeters and the axis parallelism measurement accuracy is ≤±0.2 millimeters.
The air spring pressure test gadget registers internal pressure with a precision of 0.01 MPa, and the loading speed is 400 m/min. The equipment measures roughly 5700x4500x3500 millimeters overall and its noise level when in operation is ≤80 dB.
