外観検査用のインポートされたタイヤ データとタイヤ モデルの応答のプロット

tireModelクラス、tireDataクラス、およびサポート メソッドを使用してタイヤ データをインポートし、タイヤ モデルの応答をプロットしたり、タイヤの応答を計算してプロットしたりします。

まず、tireModel.builtinメソッドを使用して tireModel オブジェクトを作成します。この例では、組み込みの "Mid-size passenger car 235/45R18" モデルを使用します。次に、Tyre Data Exchange Format (TYDEX) v1.3 ファイルからタイヤ データをインポートします。その後、plotメソッドで引数を指定して、タイヤ モデルの応答とインポートされたタイヤ データを比較します。最後に、computeメソッドを使用してタイヤの応答を計算し、元のタイヤ データと計算された応答をプロットして、差異を検証します。

この例では、Extended Tire Features for Vehicle Dynamics Blockset™ サポート パッケージが必要です。サポート パッケージのインストールを参照してください。

すべての組み込みモデルは、Magic Formula 6.2 タイヤ タイプのモデルであることに注意してください。

組み込みモデルからのタイヤ モデルの作成

組み込みモデル "Mid-size passenger car 235/45R18" から tireModel オブジェクト tm を作成します。

tm = tireModel.builtin("Mid-size passenger car 235/45R18");

dispを使用して結果を表示します。

タイヤ データのインポート

タイヤ データが格納された TYDEX のファイル名から string 配列を作成します。

tirepath = pwd;
tydexdir = dir(fullfile(tirepath,"data_tydex_files","*.tdx"));
tydexstr = join([{tydexdir.folder}',{tydexdir.name}'],filesep);

string 配列 tydexstr で指定されているファイルから、tireData オブジェクトの配列へ、タイヤ データをインポートします。tireData オブジェクトの配列の長さは、入力 string 配列と同じ長さです。各ファイルのデータは tireData オブジェクトに保存されます。許可されているタイヤ データの詳細については、タイヤ データの例を参照してください。

td = tireData(tydexstr);

mean関数を使用して、Fz データ チャネルの前処理を行い、ノイズや変動を除去します。

td = mean(td, "Fz");

タイヤ データの自動プロット

入力引数Dataを指定して、タイヤ データ オブジェクトの配列をタイヤ モデルと重ね合わせてプロットします。汎用的なプロットが自動的に生成されるため、さまざまなスイープ方向やデータ チャネルにおけるタイヤ データと比べてモデルがどのように動作するかを素早く確認できます。
