KLIPPEL R&D系统 (开发)
模组 | 备注 |
|---|---|
| 扫描振动系统 (SCN) | SCN以后处理的方式执行机械振动分析，不需要硬件 (仅需电子狗)。 |
| 高阶模态分析 (HMA) | 使用激光扫描仪进行自动测量识别模态参数（模态共振频率、阻尼、增益）和特征振动模式（模式形状）。这将膜片上复杂的振动模式分为易于理解的单个振动分量，可以研究模式的相互作用及其对声辐射和响应的影响，并可以识别出无益的振动模式。模态参数可用于调整具有相同“模态视图”的有限元模型。 |
使用激光扫描仪进行自动测量识别摇摆模式的根本原因。对质量、刚性和力因数的不平衡进行量化，并揭示每个不平衡中心在振膜上的位置。这在避免驱动单元不稳定、音圈摩擦和脉冲失真以及确保生产一致性方面很有用，特别适用于微型扬声器和耳机换能器。 |
