Man-Machine Virtual Prototyping Solution
Ergonomics is a multidisciplinary interdisciplinary discipline. The core issue of research is the coordination between people, machines and the environment in different operations. The research methods and evaluation methods involve many fields such as psychology, physiology, medicine, anthropometry, aesthetics, design, and engineering technology. The purpose of research is to guide the design and transformation of working instruments, working methods, and working environments through the application of knowledge in various disciplines, so that the characteristics of work in several aspects such as efficiency, safety, health, and comfort can be improved. The results of human-machine analysis are influenced by human physiological and psychological factors, and are divided into subjective evaluation and objective evaluation. Subjective evaluation usually uses the method of experience and questionnaire. Objective evaluation uses the method of simulation calculation to produce human-machine analysis reports and carry out design checks. At present, the manufacturing industry has adopted virtual prototype technology for product development and development. The evaluation of human-machine analysis on the basis of virtual prototypes has attracted more and more customers' attention. In response to market demand, and far launched the iVPD human-machine virtual prototype solution.
For objective evaluation, currently on the market, Delmia, 3DExperience, Jack, Process Simulate Human and other human-computer analysis software have built-in relevant evaluation indicators, but the adjustment of virtual human posture is achieved by manually adjusting the position of each joint of the human body. This method requires a long adjustment time and the results are unnatural. The real-time motion capture technology + virtual reality technology introduced by our company can record the posture data of the human body in real time and drive the virtual person in the above software. This method has a short adjustment time and the results are naturally credible. Supports first- and third-person perspective testing.
For subjective evaluation, the virtual reality system provides users with a realistic and immersive environment, giving users a sense of coexistence with the virtual prototype, so as to fully mobilize the user's emotions and enhance the seriousness of the evaluation.
This system can collect human posture data, realize the interaction between human and virtual prototype, and has an interactive editor built into the system, which can conveniently configure the interaction logic. The ease of use of various operating component placement schemes can be evaluated. Through the study of enhancing man-machine ergonomics in the design process, the characteristics of the operation in terms of efficiency, safety, health, and comfort can be improved, and the sustainable development of the enterprise can be achieved.
