Introduction

GB/T 28878.6—2016 Standard Overview

GB/T 28878.6—2016 National Standard of the People's Republic of China "Specifications for Rotating Components of Space Science Experiments Part 6: Performance Test" is a performance test standard specially formulated for rotating components of space science experimental devices. This standard specifies the test conditions, items, sequence and methods of rotating components in the development and product stages to ensure their reliability and stability in orbit.

Explanation of professional terms and practical application cases

Oil film resistance percentage time: refers to the percentage of the accumulated time that the oil film resistance is lower than the rated value in a certain period of time. This parameter is used to evaluate the performance of the lubrication system.

Dynamic balancing test: By measuring the imbalance of rotating parts, it ensures their stability at high speeds. For example, in satellite remote sensing equipment, dynamic balancing tests can effectively reduce the impact of vibration on image quality.

Background of standard formulation and technological evolution

The GB/T 28878 series of standards are managed by the National Technical Committee for Standardization of Space Science and Its Applications, reflecting my country's technological progress and quality management requirements in the field of aerospace. With the complexity of space science experiments, the performance requirements for rotating parts are constantly increasing. This part provides detailed regulations for special test conditions in vacuum environments.

Implementation suggestions

Strictly follow the test sequence specified in the standard to ensure that all required items are fully covered.
During the development stage, focus on the moment of inertia and dynamic balance indicators.
During the product stage, the monitoring of lubrication status should be strengthened to ensure long-term operational stability.
