A New Rodent Suspension Device for Low/Microgravity Simulation
A suspension automation device for simulating low/microgravity environments was de-signed to address the issue of insufficient measurement accuracy in partial load-bearing models of ro-dents that simulate low gravity loads due to human interference.Firstly,a stepping device based on STM32 microcontroller was used to control the suspension height adjustment,and the SBT440 pres-sure sensor module was used to measure the pressure value.Secondly,partial load suspension meth-od to fix experimental animals was used,so as to achieve long-term experiments and minimize dam-age to experimental animals.Finally,the STM32 microcontroller software control programs were de-veloped using Java language,simulating low/microgravity environments through comprehensive soft-ware and hardware debugging.The experimental results showed that the measurement errors for the weight of the experimental animals and 1/6 of the weight were 3 g and 2.3 g,respectively,verifying the feasibility of the suspension device.
