Invert extension force for bore and calculate flow needed for speed.
Click the grid to add ordered vertices. Edit coordinates in mm; separate holes with a blank line. The last vertex closes to the first automatically.
Choose units and enter numbers. Full-width digits and fractions such as 1/8 or 1 3/8 are accepted. Changing a unit converts the entered value.
Reference calculation only. Results do not certify suitability for an actual design or its safety.
Inputs: select a blue symbol to edit Results: red-orange values and lines
3D shows an illustrative extrusion. Its display length does not enter the section calculations. Edit dimensions in 2D.
A=[F+Floss−pb·Arod]/(p−pb); D=√(4A/π); Q=A v; Qref=Q(p+pamb)/pamb
Displayed values are rounded. Diagrams illustrate the calculation conditions. Initial material and fluid properties are examples; replace them with values for the actual material, temperature and conditions.
ReferenceEquations assume particular loads, supports and deformation ranges. Check inputs, units and the applicability of each equation. Diagrams explain conditions; they are not manufacturing drawings or proof of safety.
Material values are typical values or reference ranges, not certified product properties or ready-to-use design allowables. They vary with standards, product form, dimensions, temper and temperature. Check the specifications and inspection certificates for the actual product.
Displayed safety factors and checks apply only to the supplied inputs and calculation model. They do not automatically establish the safety of a complete design, including code compliance, service life, fatigue or joints. For actual design, manufacture and use, separately verify applicable regulations and standards, product specifications, and the necessary tests and engineering review.

押す力から必要内径を逆算し、速度に必要な流量を表示します。
選択した形状・計算方法により、使う項目は変わります。実際の計算は上の図と入力欄で行えます。
A=[F+Floss−pb·Arod]/(p−pb); D=√(4A/π); Q=A v; Qref=Q(p+pamb)/pamb
押し方向のみ。p>pb≥0、計算径>ロッド径が必要。実機のバルブ・配管流量特性と圧力過渡は含みません。平均空気消費量とは別の所要流量です。
現在選択中の方法には、操作欄の「計算式・適用条件」を使ってください。参考計算であり、設計全体の安全性を保証するものではありません。
Invert extension force for bore and calculate flow needed for speed.
The selected model determines which of these inputs and outputs apply. Use the working diagram and input panel above to calculate.
A=[F+Floss−pb·Arod]/(p−pb); D=√(4A/π); Q=A v; Qref=Q(p+pamb)/pamb
Extension only. Require p > pb ≥ 0 and calculated bore > rod diameter. Valve/piping flow characteristics and pressure transients are excluded. Required flow differs from average air consumption.
The displayed formula and conditions in the working panel apply to the currently selected model. Reference calculation only; it does not certify a complete design.
図で条件を整理してから計算し、最後に実際の部品仕様を確認します。
Understand conditions with diagrams, calculate, then verify actual specifications.
