Abstract

The invention relates to a method for evaluating a micro-gravity dual-axis gyrator, the dual-axis gyrator consists of an inner ring and an outer ring, and the method for evaluating the micro-gravity dual-axis gyrator comprises the following steps: 11) carrying out physical modeling for the dual-axis gyrator; 12) establishing three coordinate systems of a base coordinate system, an inner ring coordinate system and an outer ring coordinate system, as shown in Figure 2, wherein the base coordinate system is a fixed coordinate system; 13) utilizing the rotating vector properties of the coordinatesystems for finally deriving an apparent gravity acceleration formula of an object, wherein apparent gravity acceleration is the projection of gravitational acceleration under the inner ring coordinate system, and the value is the vector sum of the acceleration and the gravitational acceleration produced by the rotation of the inner ring and the outer ring, and 14) utilizing the apparent gravity acceleration formula and a simulation platform for evaluating the effect of simulating micro-gravity of parameter settings according to parameters set by the micro-gravity dual-axis gyrator, if the obtained apparent gravity acceleration can achieve all rotating positions, the parameter settings can simulate the micro-gravity effect.

Description

technical field [0001] The invention relates to a biaxial gyrator for simulating biological microgravity effects, in particular to a method for evaluating a microgravity biaxial gyrator. Background technique [0002] With the development of the aerospace industry, the microgravity effect in space has gradually attracted the attention of scientific researchers. Substances such as organisms and materials will show some unique characteristics in a microgravity environment, which will drive the development of science and technology in related fields. Among them, the microgravity effect of biology is a hot spot in microgravity research. one. However, due to the complex space environment and high cost, many experiments cannot be carried out. Therefore, the use of ground experimental devices to simulate microgravity effects has become the first choice for many experiments. [0003] In the simulation of the biological weightlessness effect, the microgravity gyrator (Clinostat) is ...
