人机工程学考试复习重点资料 Ergonomics is the study of the interaction between people, machinery and their working environment. Ergonomics: human - machine - environment systems engineering, ergonomics, human ergonomics, human engineering, engineering psychology, pleasant, human factors, etc. The definition of ergonomics: an analysis of the various factors in the anatomy, physiology and psychology of a persons work environment; To study the interactions between people and machines and the environment; Study how to consider work efficiency, health, safety and comfort in the work, family life and vacation time. Ergonomics research contents: 1 human body characteristic study 2 3 workplaces and the overall design of the man-machine system information transmission device design 4 environment control and safety protection design Method of study of man-machine engineering: 1 observation method 3 experiment method 4 simulation and model test method 5 computer numerical simulation method 6 analysis method 7 research method : the definition of anthropometry is determined by measuring the human body each place dimension to determine between individual and group differences in body size, is used to study the morphological characteristics, thus to provide all kinds of industrial design and engineering design of human body measurement data. There are three main methods of measurement in human body: general measurement, photographic method, three-dimensional mathematical measurement, 3. The main statistical function in the human body measurements (computing) : 1 means 2 variance 3 standard 4 sampling error (sampling error = = all sample mean standard error of standard deviation) 5 percentile PK 4. The percentile PK The percentile divides the total measurements of the group or sample into two parts, and the measured value of K % is equal to and less than it, and the measured value of (100-k %) is less than that (1) find a percentile human size If the average height is 170, SD = 10, and K % = 30
