Intelligent human platform establishing method for equipment design and evaluation

Abstract

The invention relates to an intelligent human platform establishing method for equipment design and evaluation. The method comprise the steps of 1) building a real three-dimensional digital soldier parameterized model, and controlling the human body height, weight and percentile; 2) performing individual movement simulation; 3) performing individual equipment parametric modeling and building a model base; 4) performing geometrical efficiency evaluation, biomechanical analysis evaluation, load metabolism analysis evaluation and comprehensive operational effectiveness fuzzy evaluation on single soldiers on the basis of prior standards, calculation models and independent experiment data. The main objective of the human platform is to develop individual equipment and soldier system ergonomic characteristics fully, study relations of soldiers, equipment and battlefield environments and how to design and improve the relations so as to achieve the reasonable combination, and accordingly, the developed equipment can be suitable for solider physiological and psychological characteristics, and the individual comprehensive operational effectiveness and survivability can be improved. The method can be widely applied to individual training.

Description

technical field [0001] The present invention relates to the military field, in particular to a comprehensive three-dimensional digital human body modeling and parametric control, motion simulation control, parametric modeling of individual equipment, model library construction, and man-machine evaluation for equipment design and evaluation. The intelligent avatar establishment method. Background technique [0002] Since the mid-to-late 1980s, developed countries have competed to develop "soldier systems", but there are still a large number of ergonomic problems in soldier systems in various countries, mainly because they have not fully considered the complex human-machine systems from the perspective of system engineering. Based on the principles of design in terms of modernization and intelligence requirements, soldiers are in a passive acceptance position.

Problems solved by technology

[0002] Since the mid-to-late 1980s, developed countries have competed to develop "soldier systems", but there are still a large number of ergonomic problems in soldier systems in various countries, mainly because they have not fully considered the complex human-machine systems from the perspective of system engineering. Principle design in terms of modernization and intelligence requirements, resulting in soldiers being in a passive acceptance position

Taking a certain type of helmet in our army as an example, soldiers generally report that there are uncoordinated and uncomfortable ergonomics problems during the actual wearing process: for example, the occlusion of the helmet-mounted display in front of the eyes will affect the soldier's observation of the battlefield environment, and the installation bracket must be convenient. Flip and increase the upturn angle; the brim of the helmet is low, which affects the maximum sight of the soldier's eye movement

[0003] Most foreign technologies of this kind do not support the import and export of mannequins. For example, the Jack software of Siemens can import STL format but cannot drive

In addition, the development cost of similar foreign evaluation methods is high, the cycle is long, and the market price is expensive. Jack started research and development in 1995 and invested millions of dollars. The market price of the educational version is 250,000 yuan, while the business version includes an upgrade maintenance fee of about 750,000 yuan. ; The SANTOS of the Virtual Soldier Center of the University of Iowa in the United States has been researched and developed since 2003, with a cumulative investment of 18 million US dollars

The existing human body databases used by similar foreign products are mostly based on foreign data, which do not conform to the body shape and physiological characteristics of our country's human body, and have poor timeliness

In comparison, the human body models used in similar domestic products are inaccurate, mostly based on one-dimensional measurement data, and the degree of parameterization is insufficient

Our army's individual equipment has long relied on two-dimensional design, physical application, and subjective evaluation. A large number of problems in fit, ergonomics, and tolerance cannot be seen. What you see is what you get, and repetition and waste are serious.
