Design and analysis of static pressure distribution and measurement on contact interface
The developed human body-seat surface pressure measurement system is rational and feasible,and can measure the human body and the pressure distribution dynamically and in real time.The human body seat surface pressure distribution measurement system mainly includes FSR pressure sensor array and STC15F2K60S2 microcontroller.First,the standard weight scale is used to calibrate the FSR sensor and draw the output voltage curve under different pressure inputs.STC15F2K60S2 microcontroller has eight 10-bits AD converters.System adopts RS232 serial interface with the PC for serial communication.The MATLB is employed to conduct data processing and analysis,while the band pass filter is applied for noise suppression.After filtering data in the pre-processing stage,Fourier transform is used to analyze the valid data,then use SP Tool tools for simulation.
