Embodiment Construction

[0040] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0041] The maximum reachable range of human lower limb activities, that is, the maximum reachable area. Concepts related to this concept include the maximum functional reachable domain of human lower limbs and the optimal manipulation domain of human lower limbs. The optimal control area of ​​the lower limbs of the human body is the area with higher control performance and greater comfort in the surrounding control area of ​​the human body, and this range depends on subjective and objective factors such as control efficiency and control comfort.

[0042] The maximum functional reachable area of ​​the lower limbs of the human body is the maximum reachable range of the lower limbs of the human body during the operation of the foot control device. Since the flexibility of the feet is much lower than that of the hands, the operation parts of the foot control...

Abstract

The invention relates to the technical field of ergonomics calculation, and discloses a subdivision method for measuring an activity domain of human body lower limb operation efficiency, which comprises the following steps of: 1, determining, measuring and calculating size data required by a maximum reachable domain of human body lower limb functions; 2, dividing a lower limb activity region on a vertical axis based on the measured size data of the lower limb of the human body; 3, determining and measuring coordinate values of the maximum reachable domain of the feet of the upper and lower limbs at each layer of height; 4, equally dividing the maximum reachable region plane of the lower limb; the method mainly aims at the human body lower limb activity area, approximate equivalent division of the activity area is achieved through a subdivision method, the lower limb activity area is subdivided through the method, and normativity, preciseness and accuracy of operation efficiency measurement are ensured.

Description

technical field [0001] The invention belongs to the technical field of ergonomics calculation, in particular to a subdivision method of the lower limb activity field when measuring the lower limb operation ergonomics in the operation ergonomics research. Background technique [0002] With the improvement of people's living standards, people pay more and more attention to the ergonomic requirements of product use. Ergonomics is the science that studies the matching of human characteristics with machines and the environment, aiming to achieve the overall best benefits of the human-machine-environment system and provide people with safe, efficient and comfortable working and living conditions. [0003] The control device is the device on the machine responsible for receiving the operator's control command. As the main interface of human-computer interaction, it is widely used in general industrial and daily life products. The operating safety, efficiency and comfort of the con...
