Simulating microgravity environment on the ground, mainly throughTo counteract the effect of gravity and eliminate the settling effect of gravityTwo types of technology paths are implemented, with different technologies adapted to different experimental scenarios. The specific methods are as follows:

1. Mechanical motion (mainstream biological experimental technology)

● Rotating wall bioreactorBy continuously rotating the container, keep the cells and culture medium in a suspended state to counteractGravity settling, simulating a stress free environment under microgravity, isMicrogravity three-dimensional cell cultureThe core equipment can operate stably for a long time. BioSpace-3D microgravity three-dimensional cell culture system developed by Beijing Keyu Xingye

●Falling tower/falling pipeUtilizing the weightlessness process of objects falling freely to generate microgravity, lasting from seconds to tens of seconds, suitable for short-term materials science and basic physics experiments.

●Parabolic flightThe aircraft flies along a parabolic trajectory, and each dive pull can obtain 20-30 seconds of microgravity. It has good repeatability and is commonly used in aerospace medicine and short-term biological experiments.

2. Electromagnetic Suspension (Suitable Material Experiment)

Based on the principle of magnetic levitation, the experimental sample is suspended in the air using a strong magnetic field to isolate the effect of gravity, making it suitable for solidification research and crystal growth of metals and alloys.

3. Other auxiliary methods

●Neutral buoyancy poolBy adjusting the density of the liquid, the buoyancy and gravity of the experimental object are balanced, which is commonly used for astronaut extravehicular activity simulation training and is not strictly microgravity.

●Air floating platformUsing airflow to support the experimental device, reducing friction, simulating the motion state under low gravity, suitable for dynamic related experiments.
