AI Technical Summary
Existing micro-inertial measurement devices suffer from problems such as large zero-bias error, poor vibration isolation effect, and insufficient structural reliability in complex mechanical environments.
The device employs a plug-in vibration damping assembly, including a base and clamping plates. The test piece is clamped and fixed by a limiting groove, and the elastic properties block the rigid force transmission path, thereby achieving stable support for the test piece and isolating multi-axis vibration and impact.
It effectively reduces sensor bias, improves measurement accuracy and reliability, simplifies installation steps, ensures positioning consistency, and achieves miniaturization of the structure within a limited space.
