What is the use of quartz flexible accelerometer

The application of quartz flexible accelerometer is very wide, the following are some typical applications of it.

Inertial navigation and guidance system

Missiles, aircraft, ships, combat vehicles, and other navigation guidance systems must have speed and position information. In low-requirement situations, people use airspeed meters, Mach number sensors, odometers, etc., but as the performance requirements of weapon systems Improve, the above instruments can no longer meet the requirements. The linear accelerometer can be installed in a moving object to measure its acceleration directly, and then obtain the speed and position. It has high measurement accuracy and good dynamic performance, which is much better than the air speed meter and odometer. Therefore, the use of linear accelerometers for inertial navigation guidance systems is one of its main applications.

Tilt measurement and leveling system

In a gravitational field, a linear accelerometer can measure changes in gravitational acceleration. When the sensitive axis is perpendicular to the horizontal plane, the accelerometer indicates the unit gravity acceleration; if the sensitive axis is tilted, its output is the product of the gravity acceleration and the sine function of the tilt angle. Using this principle, it can be used for tilt measurement and leveling. For example, the leveling of fire control gun sight radar and anti-aircraft radar; in addition, the tilt angle is controlled by measuring the lateral acceleration of trains and cars so that they can still drive at high speeds on curves.

Overload switch

The overload switch is used in the bullet throwing system of the missile. In this system, the trajectory of the mother bullet is calculated and set when it reaches the desired height. The overload switch mounted on the ammunition is sensitive to the axial acceleration of the mother bullet. When the preset acceleration is reached, the overload switch outputs a bullet discharge control signal, ignites the projectile, and causes the bullet to be ejected from the mother bullet. Multiple bullets head toward the target like a net made of bombs, leaving the target nowhere to hide. It is a powerful weapon against enemy positions and large equipment.
