Research on Virtual Human Motion Control Based on Computer-Assisted Multimedia Simulation.

Area of Science:

• Human-computer interaction
• Occupational ergonomics
• Virtual reality simulation

Background:

• Realistic virtual human motion is crucial for effective virtual environment design.
• Computer-aided ergonomics simulation offers a quantitative approach to analyzing human-machine interactions.
• Existing methods may lack efficiency in identifying and resolving ergonomic issues in production planning.

Purpose of the Study:

• To propose a virtual human motion control method based on computer-aided ergonomics simulation.
• To establish a simulation environment for human bodies, workpieces, and production lines.
• To provide an efficient and quantitative evaluation method for production line planning.

Main Methods:

• Establishing a simulation environment including virtual human models, workpieces, and production lines.
• Utilizing ergonomic analysis tools such as OWAS (Ovako Working Posture Analyzing System) and BSHA (Biomechanical Strength Hazard Assessment).
• Conducting ergonomic simulations to identify man-machine problems and assess virtual human motion.

Main Results:

• Simulation identified that virtual human hand loads reached up to 70% of the ultimate load during operation.
• Analysis pinpointed low storage point and machine tool heights as causes for poor posture and high loads.
• The study demonstrated the necessity of revising the production line plan based on ergonomic findings.

Conclusions:

• Computer-aided ergonomics simulation provides a valuable tool for optimizing production line design.
• Revising production line parameters, such as height, can significantly mitigate ergonomic risks.
• Advanced simulation tools like ProcessSimulate and ProcessDesigner are expected to enhance enterprise digitization efforts.
