Abstract

The invention discloses a symmetrical pendulum type micro-thrust measuring device, comprising: a first support frame, a second support frame, a first bearing, a second bearing, a support rod, a first bearing cover, a second bearing cover, and a first swing arm , a second swing arm, a first chassis, a second chassis, a first connecting piece, a second connecting piece and a high-speed camera. The invention has the characteristics of simple structure, concise calculation, small system error, strong anti-environment interference ability, high measurement accuracy, and is suitable for thrust measurement of thrusters with small thrust-to-weight ratio.

Description

technical field [0001] The invention belongs to the technical field of micro-satellites, in particular to a symmetrical pendulum type micro-thrust measuring device. Background technique [0002] Microsatellites have the characteristics of short development cycle, small quality, and low cost. Both domestic and foreign countries have been committed to the launch and networking of microsatellites. The micro-thrust of the thruster is measured. On the one hand, the precise measurement of tiny thrust needs to solve the problem of very small thrust-to-weight ratio of the thruster, such as the thrust produced by a kilogram-level thruster is millinewton level; The ground vibration, etc., can submerge the tiny thrust. [0003] Patent CN 107091705 A discloses a single-pendulum micro-thrust measuring device and a three-wire torsion micro-thrust measuring device, which convert the physical quantity of micro-thrust into displacement through the principle of mechanical balance while keep...
