- Development of The New Low-Noise Pantograph
The noise sources of the existing PS208 were investigated in the Railway Technical Research Institute’s large-scale low-noise wind tunnel (background noise level 75.6 dB at 300 km/h) using a two-dimensional microphone array (Fig. 3). Figure 4shows the results of the investigation. We found that major noise sources are mostly generated from the four...
In our previous study, we conducted numerical simulation for the upper part of the PS208 . We found that strong pressure fluctuation that generates aerodynamic noise is caused by interference between flow around the pantograph head and flow around the pantograph head support (Fig. 5); and that it is possible to reduce interference by changing the p...
A multi-segment slider is used in the PS208 pantograph head as shown in Fig. 9 to improve the contact loss ratio of pantographs . We conducted a numerical simulation for the PS208 pantograph head using the Lattice Boltzmann Method (LBM) via PowerFLOW© . Simulation settings are shown in Table 1. Mesh size was determined in regards to both its locati...
We conducted numerical simulations for the PS208 pantograph as shown in Fig. 14. The analysis revealed that the strong pressure fluctuation around the base of the lower arm is caused by separating flow from the main axle cover hitting on the windshield cover. In an attempt to reduce the pressure fluctuation, we imple-mented a 1/10 scale wind tunnel...
The hinge cover was made more compact and thinner to reduce the projected area exposed to wind, as shown in Fig. 19.
In order to examine the noise reduction performance by the above improvements, we have developed a new low-noise pantograph “PS9040” (Fig. 20). Noise reduction performance is verified by wind tunnel tests. The arrangement of the non-directional microphones is shown in Fig. 21. Measurement results and a comparison of aerodynamic noise spectrum are s...
