Abstract(J)炭素繊維強化プラスチック(CFRP)はその優れた比強度と比剛性に加えて異方性を活かした自動車の骨格構造への適用が期待される.本研究ではCFRPをボルト締結した構造部材の固有振動モード及び固有振動数を予測するための有限要素シミュレーション手法を構築し,実際の打撃試験の結果と比較してその有効性を調べた.

Translation

Abstract(E)Carbon fiber reinforced plastic (CFRP) is expected to be applied to automotive structural frames, leveraging its excellent specific strength and specific stiffness, as well as its anisotropic properties. In this study, a finite element simulation method was developed to predict the natural vibration modes and natural frequencies of structural members bolted with CFRP. Its effectiveness was evaluated by comparing the simulation results with actual hammering test results.

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.
