Pressure Distribution and Ergonomics Shape Conceptualization
نویسنده
چکیده
The pressure distribution was measured for subjects sitting on a flat, hard and horizontal support. The pressure data were analyzed for the seat force, the magnitude of the contact area, the average pressure in the contact area, the maximum pressure, and the pressure gradient. Using multiple regression relationships were found between these pressure distribution parameters, the body characteristics and the angle of the pelvis rotation. The main explaining variables were body mass, the amount of subcutaneous fat, gender, and the ectomorphic index.

Ergonomics considerations for the conceptualization of the shape of body supports
This paper presents a methodology to incorporate ergonomics data and requirements of the pressure distribution between a person and a product into computer supported conceptual shape design. The methodology is applied to a flat sitting surface. Theoretical fundamentals for the algorithms are presented.
متن کاملGeometric Model of the Human Body
Many products interact with domains of the human body. In order to increase the comfort of use, designers should consider ergonomic factors when conceptualizing the shape. The objective of our research is to develop computer support for shape conceptualization for sitting supports by consideration of the body characteristics of a user group and the contact pressure distribution. The criteria fo...
متن کاملComputer Support for Pressure Distribution Controlled Shape Design
1 INTRODUCTION Cars and vehicles are typical products that are in daily, direct and constant interaction with domains of the human body when in use. These products are manipulated with the hands or feet (control-arms, pedals), support the body (seats, beds), or provide protecting function (cabins, safety devices). In order to increase the comfort of use, designers should strongly consider ergon...
متن کاملOptimizing the Product Shape for Ergonomics Goodness Index. Part I: Conceptual Solution
An optimization procedure was developed to search for the optimum product shape. The criterion for optimization is an objective functional, the Ergonomics Goodness Index, which is based on medical, physiological and ergonomics criteria. The input configuration to be optimized is a Finite Elements Model of the human body. The independent variables for optimization were the pressure values in the...
