Calculating Static Rollover Threshold Using Automotive Tilt Table Event and MotionSolve
Preface: The automotive Static Rollover Threshold (SRT) refers to the maximum tilt angle at which a vehicle is likely to tip/roll over during a static situation. The SRT can be used to predict the vehicle lateral acceleration in which rollover may occur. Vehicles with a low Static Rollover Threshold (SRT) are at a greater…

Radioss 計算途中でマススケーリングの追加質量を減らす
落下解析などで、ボルトのプリテンションや防水パッキンのゴムを潰してから落下、などと言う状況が良くあります。その場合、ボルトの締め付けなどの準静的な解析ではマススケーリングを大きくし、計算時間を短縮させ、落下などの質量増加が結果に影響の大きい解析ではマススケーリングを控えめに適用したい、と言ったご要望を頂くことがございます。 実は、以前はそのようなことが出来なかったのですが、近年のversionから/MASS/RESETと言う機能が実装され、ご要望を実現することが可能です。 /MASS/RESET 簡単なモデルで確認しました。適当なモデルで最初にボルトを締め付け、その後落下させます。 その時のエンジンファイルの設定は下記です。…

How are the position at t=0 and gamma defined in Flux, and how is end winding impedance calculated?
Hi I am following the example "Flux - Twin Activate Coupling: IPM Motor Speed Control", focusing on Case 3, where the initial rotor position at t=0t = 0t=0 is set to 7.5°. I understand this is determined as the zero-crossing point of the phase-one voltage through back EMF analysis, as explained in the example "Brushless…
