Study of radiation characteristic measurement system of 3.5 GHz active antenna system
Autor: Keisuke Sato, Ichiro Oshima, Kota Shishido, Susumu Miura, Nozomu Sasaki, Katsumori Sasaki, Shuta Morinaga, Yukitaka Takahashi
Publikováno v: 2017 IEEE Conference on Antenna Measurements & Applications (CAMA).
In this study, 3.5 GHz AAS transmitter and receiver characteristics measurements are conducted based on the 3GPP's specification. The shapes of the EIRP and the receiver gain patterns of the AAS show good agreement with the antenna pattern of the onl

New Indexing Mechanism for Gear Cutting Using Double Differential Gear Device
Autor: Takashi Tajima, Norio Ito, Yukitaka Takahashi
Publikováno v: TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C. 63:4012-4016
The hobbing machine of recent years has positively introduced a computer numerical control (CNC) system, but many traditional hobbing machines with gear trains are still being used to produce gears. These traditional machines generally prepare many i

How to Measure the Internal Forces of a Combustion Engine
Autor: Yukitaka Takahashi, Naoki Kamimura, Toshibumi Suzuki, Kouji Urakabe, Hideo Suzuki, Shinji Wada
Publikováno v: Noise Control and Acoustics.
It has become increasingly important to reduce the powertrain vibration which mainly affects the interior noise of vehicle during acceleration. In the past a number of studies were made based on indirect methods including a calculation using measured

A Method for Identification of Powerplant Joint Properties Using FRF Data and FEM Model
Autor: Yukitaka Takahashi, Masayoshi Tsukahara, Toshibumi Suzuki
Publikováno v: Volume 1D: 16th Biennial Conference on Mechanical Vibration and Noise.
Vibration characteristics of a powerplant, an important parameter to evaluate the booming noise and the durability of each parts of an automobile is a major field of simulation analysis using the finite element method (FEM). Overall vibration charact

Dynamic relationships of reciprocating engines
Autor: Hironori Yamamoto, Koichi Takahashi, Norio Ito, Tsutomu Oda, Yukitaka Takahashi
Publikováno v: TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C. 55:925-931
Many vibration problems of combustion engines have been resolved supported by the progress of experimental measurement and computor-aided engineering systems. Dynamic theories of the piston-crank mechanisms still consist of the static equivalent mass
