Research On Distribution Characteristics Of Plantar Pressure In Multi-locomotion Mode

With the development of science and technology and the continuous demand for improving the quality of life,more and more scientific and technological achievements began to apply and benefit the community.Plantar pressure analysis is an important part of human biomechanics,it is a comprehensive research method of kinematics,anatomy,and ergonomics,which has important significance in medical test,sports training,aerospace,criminal judgement and so on.In this paper,the stress distribution characteristics of the plantar pressure under multi-motion model,such as ground walking,running,up and down stairs and abnormal gait are studied,and the following is mostly done:Firstly,this paper puts forward eight array type classification method of plantar pressure,establishing the equation of the solution function of the base feedback combination and the resultant point,and the method of solving the static friction force of the single-supported phase is studied.Secondly,this paper introduces the hardware platform of plantar pressure acquisition and acceleration signal acquisition,and developes pressure acquisition data processing software based on the MATLAB,carrying out the calibration experiment and precision analysis of PVDF.The acceleration signal data acquisition system based on LabVIEW software is also developed.Finally,this paper studies the experiment on a number of healthy young men under different speed the ground to walk,run,and proper movement up and down the steps,at the same time,studies the experiment of simulating abnormal gait.By contrasting the figures and tables and statistical analysis of the experimental results,the characteristics of the pressure distribution of the body under different modes of motion were obtained;the phase characteristics of the peak of different stress areas;the effect of speed on force size and so on.Based on this,the rehabilitation training strategies were analyzed and developed.
