Analysis of the structure of electric rail powered transfer cart

The basic parameters of the electric rail powered transfer cart are in accordance with the standard and above. The gauge is used on the railway. It is mainly used for the transportation of large and heavy goods such as electric power, metallurgy, chemical equipment and heavy machinery, large castings and forgings.

The ladle car is made of welded structure and is mainly welded by side beams, bolster beams, large beams and small beams. The material of the ladle frame is mainly high-quality carbon steel, and the bolster lower cover and the web are made of high-strength steel. The calculation is based on the requirements of the Railway Vehicle Strength Design and Experimental Appraisal Standards and the basic parameters of the vehicle.

1.The calculation conditions are:

2.Self-weight acts in a uniform structure

3.Load is distributed in the four rectangular areas of the side beam and beam

4.Straight static load = Deadweight

5.The total straight load is the straight dynamic load coefficient

6.The longitudinal tensile load ACTS on the bottom of the longitudinal beam

According to the Railway Vehicle Strength Design and Experimental Appraisal Standards the ratio of the straight deflection of the structure to the distance S between the center of the two core plates of the ladle of the ladle is used as the ratio of the spanning ratio of the electric rail powered transfer cart of the ladle car. Straight bending stiffness. Conclusion Under the vertical tightening condition of the straight total load, the stress of the side beam is less than the allowable stress. The bolster stress is less than the allowable stress and meets the stiffness requirements.
