Problems solved by technology

At present, the attitude of the load compartment is adjusted and controlled by using the roller guidance method. However, the roller guidance is realized by contact rollers, which causes the load compartment to vibrate greatly during the ejection process, which not only causes greater wear, but also mechanical vibration is introduced into the load compartment. , affect the microgravity command in the cabin, and cannot meet the higher microgravity environment control requirements

Embodiment approach

[0064] A more specific implementation is provided below, including the steps:

[0065] The power supply unit provides power for the guide controller 8, the armature coil 12 and the pose detection sensor;

[0066] The position sensor detects the pose information of the X-axis and the Y-axis of the load cabin, and sends the pose information to the signal conversion unit, which becomes a signal form that the guidance controller 8 can receive through the signal conversion unit;

[0067] The current detection unit 6 detects the current signal of the armature coil 12, and becomes a signal form that can be received by the guide controller 8 through the signal conversion unit;

[0068] Guidance controller 8 receives pose information and current information of armature coil 12;

[0069] The guidance controller 8 calculates the pose information of the Z-axis of the load cabin through key phase detection technology according to the X-axis or Y-axis pose information of the load cabin;

Abstract

The invention discloses a guide control device and method for microgravity tower falling, and relates to the field of space science and application. The device comprises an active guide assembly, a passive guide assembly and a pose detection assembly, the active guide assembly comprises a guide device, a guide rail and a guide controller, the guide rail is installed on a load cabin, and the guidedevice and the guide controller are installed in a falling tower in the moving direction of the load cabin; the passive guide assembly comprises a permanent magnet array and a conductor plate, the conductor plate is installed on the load cabin, and the permanent magnet array is arranged in the falling tower in the moving direction of the load cabin; the pose detection assemblies are arranged in the falling tower in the moving direction of the load cabin. The guide control device provided by the invention is suitable for microgravity tower falling, solves the problems of traditional roller guide vibration and abrasion, realizes static and low-speed suspension through the optimal design between the active guide force and the passive guide force, and achieves the technical effects of miniaturization and light weight of a magnetic suspension guide system.

Description

technical field [0001] The invention relates to the field of space science and application, in particular to a guide control device and method for a microgravity drop tower. Background technique [0002] Microgravity science is an important branch of space science and application. Microgravity science in the space microgravity environment helps to better understand the laws of physics, and its results also help to better carry out various activities in the space environment. The catapult drop tower is a ground-based microgravity experimental facility that realizes short-term microgravity conditions, and can provide an effective place for a large number of microgravity scientific research and experiments. [0003] The ejection-type drop tower is equipped with ejection-type microgravity facilities. After the load cabin is ejected in the vertical direction, the movement speed of the load cabin is uncertain during the lifting process, and the maximum speed can reach 125m / s. Du...
