RY Strain Gauge Rosettes with 3 Measuring Grids for Analyzing Biaxial Stress States with Unknown Principal Directions
RY strain gauges have 3 measuring grids arranged at an angle of 0°/45°/90° (types RY1, RY3, RY8, RY9, RY10), or 0°/60°/120° (types RY4, RY7). These strain gauges (SGs) are an appropriate choice for analyzing the biaxial stress state with unknown principal directions.
With these types we offer you strain gauges (SG) in various geometries and sizes, each available with temperature responses adapted to the following materials:
- Ferritic steel (10.8 ppm/K; 6.0 ppm/°F); temperature matching code: 1
- Aluminum (23 ppm/K; 12.8 ppm/°F); temperature matching code: 3
- Austenitic steel (16 ppm/K, 8.9 ppm/°F); temperature matching code: 5
- Silica/composite (0,5 ppm/K; 0.3 ppm/°F); temperature matching code: 6
- Titanium and gray cast iron (9 ppm/K; 5.0 ppm/°F); temperature matching code: 7
- Plastic (65 ppm/K; 36.1 ppm/°F); temperature matching code: 8
- Molybdenum (5.4 ppm/K; 3.0 ppm/°F); temperature matching code: 9
Insert the temperature matching code in place of the placeholder “x” to get the ordering number of the strain gauge you need. Strain gauges marked with a # symbol are only available matched to aluminum, ferritic and austenitic steel.
Save time and efforts: RY8 strain gauges are available as pre-wired versions with connection cable


Measuring grid consists of constantan, measuring grid carrier is polymide

RY: 未知の2軸負荷解析用の3ゲージ式RYロゼットひずみゲージ
このひずみゲージ(SG)は、ひずみの主要な軸方向が未知の2軸負荷の解析に適しています。 3ゲージ式RYロゼットタイプは、ゲージ配置の角度が0°/45°/90°(RY1,RY3,RY8,RY9,RY10タイプ)、または、0°/60°/120°(RY4,RY7タイプ)となっています。
HBMは3ゲージ式ロゼットSGには、様々な幾何学形状、寸法、公称(定格)抵抗値(120と350Ω)、および、鉄鋼やアルミニウム(あるいは顧客の特別仕様)に適合した温度応答をもつものがあります。
3個の計測グリッドがクオータブリッジ回路に配置されています。
第1主応力と第2主応力の計算に関する注意事項
ロゼットの3個の計測グリッド名には、アルファベットのa、b、cが使用されています。それに従って、3ヶ所のひずみεa、εb、εcが、3個のロゼット計測グリッドで計測されます。 主要な一般応力σ1とσ2は、0°/45°/90°のロゼットで、以下の公式を使用して計算されます:
そして、0°/60°/120°のロゼットでは:
主方向は以下で決定しています。最初に、補助の角度ψに対する接線が計算されます。 0°/45°/90°のロゼットは以下の公式を使用します:
そして、0°/60°/120°のロゼットには、公式に従って:
注意: 直角三角形の角度に関する接線は反対側(分子N)と隣接側(分母D)の比率です:
接線のこのあいまいさのため、上記の2つ数の商の最終的な計算を行う前に、分子(N)と分母(D)のサインを決定する必要があります。 角度ψが円のどの四分円にあるかを知る唯一の方法であるので、サインを決定するのは重要です。 最初に、タンジェントの値から中間的角度ψの値を決定してください:
次に、以下のアプローチを使用して、角度を決定してください:
この様にして、基準計測グリッド”a" の軸から開始して、数学的にポジティブな方向(反時計回り)で見つけられる角度 ϕを適用してください。計測グリッドの軸”a" は角度 ϕの一方のアームを形成しますが、もう片方のアームは第一主方向を表します。これは主要な一般応力σ1(主要なひずみ方向ε1と同じ)の方向です。 角度のポイントは計測グリッド軸の交差点に位置しています。 第二主方向(主要な一般圧力σ2の方向)は、角度 ϕ+90°です。
計測グリッドはコンスタンタンでできています; 計測グリッドを保持している材料はポリイミドです。
また、RY6/RY8ひずみゲージには、接続ケーブルが付属しています。多くの利点がある実用的ソリューション: 計測ポイントで、はんだ付けが不要です。ケーブル長は0.5m~10mで要求に応じてRJ11プラグが利用可能です。 ひずみゲージのフルオロポリマ絶縁配線は、ケーブル設置時に、張り付くのを防ぎます。 皆様の役に立つ実務的なソリューションを提供します!
Simplified Documentation and Parameterization
To optimize the measuring point documentation each strain gauge includes two stickers which can be placed next to the measuring point and near the measuring amplifier. Benefit from the parameter information directly in the measurement setup:
- QR code that directly links to the data sheet of the respective strain gauge
- The product and production batch numbers
- The k-factor and a additional space for your notes
- QR code containing the values of the individual strain gauge to simplify computer-aided parameterization or documentation with a scanner
Please note: newly produced strain gauges all come with the sticker in stock, strain gauges still in stock do not have this feature yet.
