Embodiment Construction
[0034] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.
[0035] Microsatellites have attracted the attention of various countries because of their small size, light weight, low cost, and short launch cycle. Usually, multiple satellites are launched with one arrow. The satellites in orbit are unlocked and separated, and the separation force is required to be small. The present invention provides a method for measuring the micro-separation force using high-speed photography on the background of star separation. The steps are as follows: 1. Build a separati...

The invention provides a micro-separating-force measurement method based on high-speed photography. The micro-separating-force measurement method based on high-speed photography comprises the steps of setting up a separation device separating-force measurement platform; fixing a small satellite simulator to be separated on the separation face by using a separation device and performing unlocking device power supply safety checking; installing a high-speed photography device and a ruler; aligning the high-speed photography device to the separation device, installing the ruler on the separation device separating-force measurement platform and correcting a horizontal position; using the high-speed photography device to shoot the separation process so as to calculate separating force; starting the high-speed photography device and a separation power supply control switch and stopping photography after a screw to be separated flies out and falls onto the ground; calculating the separating force according to changing ruler scales corresponding to the screw in each image. The micro-separating-force measurement method based on high-speed photography can accurately calculate the separating force of the micro-separation device.
Description
technical field [0001] The present invention relates to a method for measuring micro-separation force, in particular to a method for measuring micro-separation force based on high-speed photography. Background technique [0002] The microsatellite cluster launch needs to control the separation force of the separation and unlocking device of the microsatellite according to the mission requirements, so as to meet the separation angle and angular velocity control requirements. Because the separation force of the separation device is generally small, the separation force cannot be measured by traditional methods. Therefore, it is necessary to design a technical solution that can estimate the separation force of the micro-separation device more accurately. Contents of the invention [0003] Aiming at the defects in the prior art, the purpose of the present invention is to provide a measurement method based on differential separation force under high-speed photography.
