使用说明与常见问题How-to & FAQ

「振动加速度/速度/位移换算」是什么？What is the Vibration Acceleration / Velocity / Displacement Calculator tool?

按正弦振动关系在频率、加速度、速度、位移之间换算：填任意两项即可算出其余各项，同时给出峰值、有效值（RMS）和峰峰值，支持 m/s²、g、mm/s、μm 等单位。Convert between frequency, acceleration, velocity and displacement for sinusoidal vibration: fill in any two and get the rest as peak, RMS and peak-to-peak values, in m/s², g, mm/s, μm and more.

如何使用「振动加速度/速度/位移换算」？How do I use the Vibration Acceleration / Velocity / Displacement Calculator?

先选择输入值是峰值、有效值还是峰峰值，然后在频率、加速度、速度、位移中任意填写两项（其余留空），结果表会列出所有量的峰值、RMS 和峰峰值。适用于单一频率的正弦振动。Choose whether your inputs are peak, RMS or peak-to-peak, then fill in any two of frequency, acceleration, velocity and displacement (leave the others blank). The table lists every quantity as peak, RMS and peak-to-peak. Valid for single-frequency sinusoidal vibration.

计算公式是什么？What formulas are used?

对单一频率的正弦振动：速度 = 加速度 ÷ (2πf)，位移 = 速度 ÷ (2πf) = 加速度 ÷ (2πf)²。以上都用峰值计算；有效值 = 峰值 ÷ √2，峰峰值 = 峰值 × 2。For single-frequency sinusoidal vibration: velocity = acceleration ÷ (2πf) and displacement = velocity ÷ (2πf) = acceleration ÷ (2πf)². All are peak values; RMS = peak ÷ √2 and peak-to-peak = 2 × peak.

设备振动标准一般用哪个量？Which quantity do machine vibration standards use?

旋转机械（如 ISO 10816/20816）通常用 10–1000 Hz 范围内的速度有效值（mm/s RMS）评价；低频大位移常用位移峰峰值（μm），高频冲击常用加速度（g）。Rotating machinery standards such as ISO 10816/20816 usually use RMS velocity (mm/s) over 10–1000 Hz; low-frequency large motion uses peak-to-peak displacement (μm), and high-frequency impacts use acceleration (g).
