Dynamic Response Reveals Changes That Displacement Alone Cannot动态响应揭示位移数据无法单独说明的变化
Acceleration records how a structure responds to traffic, wind, rotating equipment, hydraulic excitation and impact. Frequency, phase and amplitude together support modal identification, operating-condition comparison, event capture and fatigue assessment.加速度记录结构对交通、风、旋转机械、水力激励与冲击的响应。频率、相位与幅值共同支撑模态识别、工况对比、事件捕捉与疲劳评估。
Stiffness and Boundary Change刚度与边界变化
Natural-frequency and mode-shape shifts provide repeatable evidence of structural-system change.自振频率与振型变化为结构体系变化提供可重复的证据。
Operating Response运行响应
Peak, RMS and band energy quantify vibration under traffic, machinery and environmental loads.峰值、RMS 与频带能量量化交通、机械和环境荷载下的振动。
Mode and Load Path振型与传力路径
Synchronized channels preserve relative phase for operational and experimental modal work.同步通道保留相对相位，用于运营与实验模态分析。
Impact and Abnormal Events冲击与异常事件

Inertial Force Becomes a Charge Signal把惯性力转换为电荷信号
A seismic mass applies force to a piezoelectric element as the sensor body accelerates. The generated charge is proportional to force and therefore to acceleration within the calibrated operating range.传感器壳体运动时，惯性质量对压电元件施加作用力；在标定工作范围内，产生的电荷与力成正比，从而与加速度成正比。
Charge or IEPE Output电荷输出或 IEPE 输出
Charge-output sensors place the piezoelectric element directly at the measurement front end. They suit high temperature, long cable specialization and charge-amplifier systems. IEPE sensors integrate a low-impedance converter and use constant-current excitation, simplifying field wiring and improving immunity to cable noise.电荷输出传感器将压电元件直接接入测量前端，适用于高温、专用长电缆和电荷放大器系统；IEPE 传感器内置信号转换，以恒流方式供电，现场接线更简单，并降低电缆运动噪声的影响。
