Problems solved by technology
These carriers usually work in the worst mechanical environment. When the motion of the carrier changes, such as acceleration, roll, pitch, yaw, take-off, and landing, the vibration, shock or noise generated by the engine will be transmitted to the sensitive parts inside the MIMU. Components, the system will generate dynamic errors, resulting in reduced output accuracy of sensitive components

The invention discloses an impact resistance minitype inertial measurement unit with adjustable damping, and relates to the technical field of minitype inertial measurement units. The impact resistance minitype inertial measurement unit comprises a minitype inertial measurement unit upper cover, a sealing pad, an inertial assembly body, a damper and a minitype inertial measurement unit lower shell. The damper is fixed into the lower shell; the inertial assembly body is fixed to the damper; the upper cover seals the lower shell; and the sealing pad is arranged between the upper cover and the lower shell to enable a closed space to be formed between the upper cover and the lower shell; the damper and the inertial assembly body are sealed in the closed space; and a gap is reserved between the inertial assembly body and the lower shell. The impact resistance minitype inertial measurement unit can attenuate high vibration and high impact capacity, has the characteristics of being easy to implement and adjustable in damping, and improves the measurement accuracy and performance of the measurement unit.
Description
technical field [0001] The invention relates to the technical field of miniature inertial measurement units, in particular to an impact-resistant miniature inertial measurement unit with adjustable damping. Background technique [0002] With the in-depth research on micro-electro-mechanical systems (MEMS), compared with traditional micro-inertial measurement units, MEMS micro-inertial measurement units have the advantages of low cost, small size, light weight, and high reliability, and their application fields are constantly expanding. Miniature Inertial Measurement Unit (MIMU) is the core component of inertial navigation system, which is widely used in military and civilian systems such as aircraft and ships. These carriers usually work in the worst mechanical environment. When the motion of the carrier changes, such as acceleration, roll, pitch, yaw, take-off, and landing, the vibration, shock or noise generated by the engine will be transmitted to the sensitive parts insi...
