Abstract(J)	各国で強化されるCO₂排出規制を達成するために，モータなどの電動パワートレインを用いた電動車の開発が加速している。電動車は，燃費向上のためにエンジンを停止させることが多く，電動パワートレイン由来の振動・騒音が問題となる。本報告はその振動・騒音の発生メカニズムとインバータ制御による低振動化手法を紹介する。 Translation
Abstract(E)	Automakers and suppliers are accelerating the development of electric vehicles to achieve CO₂ emission regulations. Electric vehicles stop the engine at zero or low speed to improve fuel efficiency. Therefore, noise and vibration derived from the electric power train are often a serious issue. In addition, to be compared with the engine frequency, the frequency of the electric power train spreads a wide range from 10 Hz to 20 kHz. The frequency of noise and vibration may match the resonance frequency of the mechanical components. In this report, we describe these generation mechanisms and explain low vibration control to change inverter control.

About search

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.

If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).

Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.

Example) X AND Y → "X and Y (including)" X OR Z → "X or Z (including)"

If AND and OR searches are mixed, OR search has priority.

Example) X AND Y OR Z → X AND (Y OR Z)

If AND search and multiple OR search are mixed, OR search has priority.

Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.

The number in "()" after each item is the number of data that includes that item.

Search tips

When searching by author name, enter the first and last name separated by a space, such as "Taro Jidosha".
