Armchair design optimized experiment system

Abstract

The invention discloses an experimental system of chair optimum design, which consists of three-dimensional digital adjustable chair model and distributed body-pressure measuring system, wherein the three-dimensional digital adjustable chair model is basic to measure the body-pressure distribution of man-chair touching boundary, which accomplishes the measurement and analysis of body-pressure distribution index for different form groups or kinds of chairs and body gestures of individual; the experimental system draws the plane isobaric map, pressure distribution map and chromatographic map due to the measuring and calculating result of maximum pressure, even pressure, maximum pressure gradient, even pressure gradient, unsymmetrical coefficient, longitudinal pressure distribution curve and longitudinal moment distribution curve, which provides the unsymmetrical coefficient, on-line pressure distribution data, curve and three-dimensional display of pressure distribution. The invention is convenient to operate with high measuring and analyzing efficiency, which improves the precision of measuring data.

Description

Technical field [0001] The invention belongs to the technical field of ergonomics, and relates to an experimental device, in particular to an experimental system for seat optimization design. Background technique [0002] The seat is a common necessity in people's work, study and life. The pros and cons of the seat design will directly affect the comfort of sitting people, and affect people's work and life quality. A large number of studies have shown that if the comfort of the seat is not good, it will not only cause fatigue of the sitting person, but also often cause various diseases such as human spine bones, digestion and cardiovascular diseases. For example, waist fatigue of car drivers is a major problem that has received increasing attention at home and abroad in recent years but is difficult to solve. Therefore, the comfort of the seat has attracted more and more attention and people at home and abroad. [0003] The comfort of the seat is generally considered to include t...

Problems solved by technology

The automobile seat body pressure distribution test system developed by Tsinghua University in my country can be used to test the pressure distribution on the human-chair contact surface of the automobile seat. Its purpose is to provide an objective basis for the comprehensive evaluation of the comfort of the automobile seat. At the same time, the test results can also be used to guide the design of car seats to achieve better body pressure distribution performance or to save seat cushion materials as much as possible without affecting the comfort of the seat, but this system has not considered and researched Changes in body pressure distribution caused by changes in the contact interface of the seat (including geometric dimensions of the seat, shape changes of the seat cushion and back cushion, and various seat regulators)

Moreover, among the related products, there is no case that integrates ergonomics and biomechanics to study the quantitative ergonomics evaluation method of the seat.
