Abstract(J)マツダでは「走る歓び」と「優れた環境・安全性能」を目標に,安全・安心なクルマと社会の実現を目指した商品開発を実施している。その中で,衝突安全性能開発は,高い安全性能と軽量化という背反傾向にある課題を両立させるために,MBD( Model Based Development) を駆使して車両構造を開発している。SKYACTIV VEHICLE ARCHITECTURE に代表される車体開発では,高精度CAE 技術を用いて,衝突時の荷重を効率的に分散させるマルチロードパスを進化させた新しい構造を作り上げた。 Mazda MX 30 は,EV モデルとフリースタイルドアという2 つのユニークな特徴をもっており,これらの特徴と高い衝突安全性能を高次元で両立させる構造を織込んで,欧州の衝突安全アセスメント(New Car Assessment Program: NCAP)であるEuroNCAP で,2020 年に最高ランクの5★を獲得した。本稿では,代表的な衝突モードである前面衝突,側面衝突,後面衝突,歩行者保護について織り込んだ技術を紹介する。

Abstract(E)Aiming at realizing safe and secure cars and society, Mazda is striving to achieve “excellent environmental and safety performance” and “driving pleasure”. In crash safety development, Mazda uses MBD (Model Based Development) to develop vehicle structures with the aim to achieve the two conflicting properties, light weight and safety performance, at a high level. In vehicle body development characterized by Mazda’s Skyactiv-Vehicle Architecture, a new body structure was developed by using high-accuracy CAE Technology. This is a structure evolved from the multi-load path structure that e ciently disperses collision loads. The ALL New Mazda MX 30 has two unique features: EV model and freestyle door. Coming with the structure that makes these features compatible with high crash safety performance, the Mazda MX 30 got EuroNCAP’s best rating 5★ in 2020. This report introduces the technologies incorporated in typical crash modes of vehicles: frontal impact, side impact, rear impact and pedestrian protection

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".
