chance failure periodとは 意味・読み方・使い方

The lifetime t_1 of components is calculated from the early failure period and chance failure period of a failure factor curve, and the number of failures due to the lifetime of components is calculated from the number of lifetimes of components in a predetermined period T.例文帳に追加

故障率曲線の初期故障期間と偶発故障期間とにより部品の寿命ｔ_１を算出し、所定の期間Ｔにおける部品の寿命数から部品の寿命による故障数を算出する。 - 特許庁

The bathtub curve S0 is periodically read out from the storage portion 3B to determine a remaining lift time for the boundary point (B point) between the chance failure period and the wear-out failure period on the bathtub curve S0, and the remaining lift time thus determined is transmitted to the monitoring device and displayed on a monitor screen.例文帳に追加

定期的に、記憶部３Ｂからバスタブ曲線Ｓ０を読み出し、このバスタブ曲線Ｓ０における偶発故障期間と摩耗故障期間との境界点（Ｂ点）に対しての余寿命時間を求め、上位の監視装置へ送り、そのモニタ画面上に表示させる。 - 特許庁
