Abstract(J)クランクジャーナル試験機を用いて、すべり軸受と試験軸の焼付き特性を調査した。焼付き判定トルク上昇値に至る負荷荷重より前に、低荷重で複数回の小さなトルク上昇を観察した。それらのトルク上昇時にAEセンサにて検出した波形は、全て同じ周波数帯を示した。この小さなトルク上昇が焼付きに至る要因と考えられる。

Translation

Abstract(E)The seizure phenomenon between the journal and plane bearing was investigated by using crank journal tester. The small torque spikes at multiple times were observed at lower loads before that to be measured as exceeding the seizure torque. It was found that these shapes of increasing torque curves were consisted of two stages, and the AE signal at that time was observed in almost the same frequency band. It was estimated that this small torque rising was a trigger to generate the seizure.

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.
