Description

Technical Field

[0001] This utility model relates to the field of electrical interface testing technology for satellite reaction flywheels, and in particular to a mass production electrical interface testing platform for reaction flywheels. Background Technology

[0002] With the development of aerospace technology, satellite platforms are gradually moving towards miniaturization, mass production, and high integration. As a key actuator in the satellite attitude control system, the reliability and stability of the reaction flywheel directly affect the control accuracy and on-orbit stability of the entire satellite. Therefore, before the flywheel is delivered for use, it is necessary to conduct rigorous electrical performance tests and interface consistency verification to ensure that it meets the design specifications.

[0003] Currently, electrical interface testing of reaction flywheels typically involves manually connecting each test device one by one, with the test object being a single device, lacking an integrated testing platform. This traditional method suffers from problems such as low testing efficiency, high wiring error rate, susceptibility to human interference, poor data consistency, and prominent issues with insertion and removal lifespan.

[0004] The preceding description is intended to provide general background information and does not necessarily constitute prior art. Utility Model Content

[0005] The purpose of this invention is to provide a reaction flywheel mass electrical interface testing platform, which significantly improves the efficiency of mass testing.

[0006] This utility model provides a batch testing platform for reaction flywheel electrical interfaces, including a test carriage and test control equipment. The test carriage includes an upper platform, a lower platform, and connecting columns. Both the upper and lower platforms are rectangular plates, arranged parallel to each other at intervals, and their four corners are fixedly connected by the connecting columns. The test control equipment includes a host computer, an oscilloscope, a constant current source, and an isolation test box. The host computer, oscilloscope, constant current source, and isolation test box are all mounted on the upper platform, and the oscilloscope and constant current source are connected to the isolation test box. A main test channel is provided on the lower platform, and multiple flywheel mounting grooves are provided on both sides of the main test channel. The flywheel mounting grooves are connected to the main test channel through sub-test channels. A test connector is provided at the connection between the sub-test channels and the flywheel mounting grooves. The test connector is connected to a control switch via a wire, and the control switch is connected to the isolation test box via a wire. The wire is located in the sub-test channel and the main test channel.

[0007] Using the above technical solution, when using the batch electrical interface testing platform for reaction flywheels, the reaction flywheels are placed in the wheel mounting grooves, and the communication interface of the reaction flywheels is connected to the test connector. The host computer is used for signal transmission, the constant current source provides a constant voltage, and the oscilloscope displays the signal waveform. The host computer simultaneously acquires the waveform and data from the oscilloscope to avoid errors caused by manual reading and counting. Each reaction flywheel acquires electrical signals through an integrated isolation test box via an oscilloscope. The isolation test box integrates isolation circuits and a switching module to avoid electrical interference. The reaction flywheels are placed in the flywheel mounting grooves to prevent external forces from causing test signal deviations. Each flywheel mounting groove has independent power supply access, independent signal transmission, and independent switch control through the test channel, ensuring that each reaction flywheel is not interfered with by other flywheels during the test.

[0008] Furthermore, support rods are vertically connected to the four corners below the lower platform, and rollers are connected to the other end of the support rods.

[0009] Furthermore, four flywheel mounting grooves are provided on both sides of the main test channel, and the distance between adjacent flywheel mounting grooves is the same.

[0010] Furthermore, the surfaces of the upper and lower countertops are covered with an antistatic material.

[0011] This utility model discloses a batch testing platform for reaction flywheel electrical interfaces. After the test equipment parameters are set, each flywheel can be tested for all electrical interface items (surge, ripple, telemetry, time constant, level signal, etc.) in one go, improving testing efficiency and shortening delivery cycles. It reduces the number of insertions and removals, as increased insertions and removals can affect the mechanical wear and structural loosening of product connectors; repeated stress on connectors can cause localized overheating or arcing, accelerating material fatigue and aging; and surface wear can lead to increased contact resistance or signal loss. It improves test consistency and accuracy, with each flywheel tested in its corresponding channel, and oscilloscope data read by the host computer, reducing human error and improving overall test quality. Isolation and overcurrent / overvoltage protection designs ensure reliable communication between the test flywheel equipment and the test platform. It significantly improves the efficiency of batch testing; each flywheel uses an independent control switch for power switching, ensuring independence between different flywheels and avoiding misoperation or interference; and the integration of the host computer and the test system enables automated testing, reducing human error.
