Title: Sound arrester for pantograph
Inventor: TERADA KATSUYUKI
IPC: B60L5/24
Filed: 1989-07-17
Abstract: PURPOSE:To reduce echos in sound-arresting walls so as the display sufficient sound-arresting effect by forming the distance between the sound source and the sound-arresting walls to be the value of odd-times (especially close to three times) longer than one quarter of the wavelength of the main sound. CONSTITUTION:A bottom wall 6' is provided close to the position of 3/4 (three- quarters) of wavelength lambda from the sound source S and formed into a stream line. A rear inner wall 10' in the form of a stream line is also provided close to the position of 3/4 lambda from the sound source S. The sound arrestor 7' of a pantograph is formed of the respective sound-arresting walls of the bottom wall 6' and the inner walls 9', 10'. Accordingly, the sound source S is positioned at the node of sound pressure P so as not to excite the wave of the sound pressure P. An echo therefore small, and the sound 7' can display its sound- arresting effect sufficiently without being weakened by the echo. Furthermore, because of the streamlind formation of the inner walls 9', 10', air current flows smoothly and the air resistance of the sound arrestor 7' is small whichever side between the front and back of the proceeding direction of the vehicle the respective inner walls 9', 10' are placed.
