Abstract(J)	モータースポーツにおけるドリフト走行は，駆動力を向心力とすることで旋回を行うため，駆動力のモデル化が不可欠である．本研究では，接地面速度に着目した動摩擦タイヤモデルを導入し，数式演算による解析が可能な車両モデルを提示する．そして，四輪駆動車のドリフト走行における舵角やすべり角について検討を行った． Translation
Abstract(E)	Drifting in motorsports utilizes traction force as centripetal force during cornering; therefore, modeling of the traction force is indispensable. In this study, we introduce a vehicle model that incorporates a kinetic-friction tire model focusing on contact patch velocity, enabling analytical calculations. Furthermore, we examine the steering angle and slip angle in drifting of four-wheel-drive vehicles.

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".
