Study On Test Method Of Walking Forces Using The Human Body Acceleration Monitoring System

With the increase of the long-span structure vibration problems caused by pedestrian loads,the researches on theory and experiment of walking forces have been paid more and more attention.However,the traditional test methods of walking forces are insufficient more or less.In order to improve the existing test methods of walking forces,this paper designed and developed a test method of walking forces by using the human body acceleration monitoring system based on the modified bipedal walking model,and organized a number of specific tests under different speed conditions.Relevant conclusions are obtained after processed and analyzed the test data,and detailed contents are as follows:1.Through studying the present situation of test methods of walking forces at home and abroad,for the insufficient of existing experiment researches on force plate and pressure shoe,it is proposed a test method of walking forces by measuring the body acceleration with acceleration sensors.2.Based on the modified bipedal walking model,the equilibrium equations between body acceleration and walking force was established,further the test method of walking force by using the human body acceleration monitoring system is proposed.And combined with the simulating calculation to confirm the test method of walking force by using the human body acceleration monitoring system is theoretically feasible and accurate.3.The whole process of design and manufacture about the human body acceleration monitoring system and the total plantar pressure monitoring system been introduced in this paper.It clarified the design thinking and structure of test equipments,and explained the sensor choices of parameter and position,the selection of component materials,and the calibration of pressure sensor one by one,which to ensure test equipments meet the requirements.4.Organized some specific testers to walk in different speed conditions and get relevant test data of walking force.Through comparative analysis between the test data and simulation value of the modified bipedal walking model,the following conclusions are obtained:(1)The test method of walking force by using the human body acceleration monitoring system is operable and valid;(2)The walking characteristics measured by the human body acceleration monitoring system is basically consistent with simulation value of the modified bipedal walking model;(3)The human body acceleration monitoring system can not effectively reflect the difference of walking characteristics of different human body parameters testers under different speed conditions.
