振动隔离
本主题展示了如何确定振动水平是否过高，并列出了一些改善振动特征的简单步骤。
综述
Flight Control boards with in-built accelerometers or gyros are sensitive to vibrations. 高振动会引发一系列问题，包含飞行效率或性能降低，缩短飞行时间，增加机体磨损。 在极端情况下，振动可能会引发传感器削波失真/故障，可能导致姿态估算失败，失控。
设计很好的机身会在自驾仪安装的位置处减少特定结构共振的幅度。 为了将振动降低到敏感元器件能够处理的程度，进一步的隔离是需要的。（例如 ，一些飞控必须使用某种防震泡沫安装固定在机身上，其他的是一些内部隔离）。
振动分析
Log Analysis using Flight Review > Vibration explains how to use logs to confirm whether vibration is a probable cause of flight problems.
基本振动修复
可以减少振动的一些简单步骤：
- 确保所有的东西都可靠的固定在机身上（起落架，GPS 天线等）。
- 使用平衡螺旋桨。
- 确保使用高质量的螺旋桨、发动机、电调和机架。 这些组成部分中的每一个都有很大的不同。
- 使用隔振方法安装自动驾驶仪。 Many flight controllers come with mounting foam that you can use for this purpose, while others have inbuilt vibration-isolation mechanisms.
- As a last measure, adjust the software filters. 最好是减少振动源，而不是在软件中过滤。
