Application of Clothing Ergonomics in Clothing Design

With the continuous development of society and culture,clothing is not just to make people feel warn. Production, design, and continuous innovation of appare aim to make clothing serve people better, satisfy the demand of more people, and let people feel more comfortable, safer, more hygienic and more convenient. People would have more scientific and effective way in dominating his own clothing style, making clothes serving for people.

Applications and research trends of digital human models in the manufacturing industry

Virtual reality(VR)has been widely used in various manufacturing industries,and VR-based virtual manufacturing has received significant attention in the current intelligent manufacturing era.Digital human models(DHMs)are essential for virtual manufacturing applications.Additionally,researching new applications of DHMs has developed into an important academic research field.This paper aims to identify the applications and research trends of DHMs in the manufacturing industry and to provide a reference for the continued development of virtual manufacturing and DHMs.We selected a total of 49 related articles from a large number of articles published between 2014 and 2019.The applications of DHMs in the manufacturing industry are analyzed from different perspectives and various relevant technical limitations are discussed.The results indicate that the applications of DHMs differ significantly between different types of fields.The automotive industry is the main application field for DHMs,and assembly/maintenance simulations and evaluations are the main application types.Additionally,there are still some limitations in the establishment of virtual environments,motion control,and DHM evaluation that should be addressed.Finally,research trends in the application of DHMs are illustrated and discussed,including the planning and assessment of human-robot collaboration systems,the combination of DHMs and augmented reality,and improved motion planning for DHMs.In summary,the application of DHMs can improve the realism and effectiveness of virtual manufacturing,and DHMs will be more widely and deeply studied and applied in various manufacturing industries in the near future.

Fatigue Analysis and Evaluation Method of Ergonomic Virtual Human

The ergonomic digital design and evaluation of man-machine system is the main application fields of virtual human technology. Because of the complexity of physical person and uncertainty of fatigue generation mechanism, it is difficult to express a nd evaluate the Virtual Human's fatigue state. This paper summarizes the characteristics of virtual human's fatigue evaluation, such as undeterminable, invisible, the constraint conditions can been used. Viewed from the strengths and weaknesses of preexisting models, metabolic energy expenditure model, dynamic muscle fatigue model and a model to assess fatigue at joint-level using the half-joint concept, this paper puts forward the future development trend that the combination of subjective and objective,diversificationoftheanalyzablemotion,real-timeandvisualexpression.
