Description

【０００１】
【発明の属する技術分野】
本発明は、超電導磁気浮上式鉄道用超電導磁石の振動試験装置に関するものである。
【０００２】
【従来の技術】
従来の超電導磁気浮上式鉄道用超電導磁石の振動試験では、１台の加振器のみを用いて試験をするようにしている。
【０００３】
【発明が解決しようとする課題】
しかしながら、上記した従来の超電導磁気浮上式鉄道用超電導磁石の振動試験装置では、用いる加振器が１台のみであるため、超電導磁気浮上式鉄道用超電導磁石の局所的な振動試験に限られ、走行中に発生する振動モードを多様に再現させることはできなかった。
【０００４】
本発明は、上記状況に鑑みて、超電導磁気浮上式鉄道用超電導磁石の走行中に発生する振動モードを多様に再現させることができる、信頼性の高い超電導磁気浮上式鉄道用超電導磁石の振動試験装置を提供することを目的とする。
【０００５】
【課題を解決するための手段】
本発明は、上記目的を達成するために、
〔１〕超電導磁気浮上式鉄道用超電導磁石の振動試験装置において、ベースとなる基礎部と、この基礎部上にＸ軸及びＺ軸方向に可動に配置される複数個の加振機と、この加振機に対向するように配置される超電導磁気浮上式鉄道用超電導磁石と、あらかじめ設定される超電導磁気浮上式鉄道車両の速度に応じた多様な振動モードを生成させる前記加振機の制御装置とを具備することを特徴とする。
【０００６】
〔２〕上記〔１〕記載の超電導磁気浮上式鉄道用超電導磁石の振動試験装置において、前記複数個の加振機は２個であることを特徴とする。
【０００７】
〔３〕上記〔１〕記載の超電導磁気浮上式鉄道用超電導磁石の振動試験装置において、前記複数個の加振機は３個であることを特徴とする。
【０００８】
【発明の実施の形態】
以下、本発明の実施の形態について詳細に説明する。
【０００９】
図１は本発明の実施例を示す超電導磁気浮上式鉄道用超電導磁石の振動試験装置の模式図である。
【００１０】
この図において、１はベースとなる基礎部、２〜４はその基礎部上に配置される複数個（ここでは３台）の加振機、５〜７は複数個（ここでは３台）の移動機構、８はその３台の加振機２〜４に対向するように配置される超電導磁気浮上式鉄道用超電導磁石である。
【００１１】
１０は３台の加振機２〜４の３台の位置情報を受け取り、３台の加振機２〜４の加振条件を指令する加振機制御装置であり、この加振機制御装置１０内には、インターフェース回路１１、超電導磁気浮上式鉄道用超電導磁石８が走行中に発生する多様な振動モードを生成できる、換言すれば、走行中に発生する多様な振動モードを再現できる振動モード生成加振機情報を記憶した記憶装置１２、制御部１３、入出力部１４などを有している。
【００１２】
そこで、この実施例では、３台の加振機２〜４の位置をＸ軸又はＺ軸方向に制御して超電導磁気浮上式鉄道用超電導磁石８を振動させる。なおかつ、３台の加振機２〜４の位置を加振機制御装置１０の記憶装置１２からの情報、つまり、走行中に発生する多様な振動モードを生成できる振動モード生成加振機情報に基づいて制御することにより、周波数ごとに異なる特定の振動モードを励起させることが可能となる。
【００１３】
なお、正確には、超電導磁気浮上式鉄道用超電導磁石は、図示しないが内部に内槽容器に納められた超電導コイルと、その超電導コイルの荷重支持体（ばね）と、その荷重支持体（ばね）が固定される外槽容器としてのクライオスタットからなるが、ここでは、それらを全て構成したものを超電導磁気浮上式鉄道用超電導磁石と呼ぶことにする。
【００１４】
図２は本発明にかかる超電導磁気浮上式鉄道用超電導磁石の走行中に発生する振動モード（その１）を示す図であり、ここでは、超電導磁気浮上式鉄道用超電導磁石８がへの字形状に変形した状態２１と略直線状の状態２２とが示されている。２３は台枠であり、その台枠２３も超電導磁気浮上式鉄道用超電導磁石８の変形に対応して変形している。
【００１５】
図３は本発明にかかる超電導磁気浮上式鉄道用超電導磁石の走行中に発生する振動モード（その２）を示す図であり、ここでは、超電導磁気浮上式鉄道用超電導磁石８がＷ字形状に変形した状態３１と略直線状の状態３２とが示されており、３３は台枠であり、その台枠３３も超電導磁気浮上式鉄道用超電導磁石８の変形に対応して変形している。
【００１６】
かかるＷ字形状に変形した状態３１の振動モードを生成させる時には、図１に示したように３台の加振機を配置する方がその振動モードを発生させやすいが、図２に示したへの字形状に変形した状態２１の振動モードを生成させる時には、２台の加振機を配置させるだけでもよい。
【００１７】
本発明によれば、このように、複数個の加振機の位置の制御を行うことにより、超電導磁気浮上式鉄道用超電導磁石を多様な振動モードを生成させることができ、信頼性の高い超電導磁気浮上式鉄道用超電導磁石振動試験を行うことができる。
【００１８】
なお、本発明は上記実施例に限定されるものではなく、本発明の趣旨に基づいて種々の変形が可能であり、それらを本発明の範囲から排除するものではない。
