Ergonomic analysis
In assembly and production operations, taking into account the increasing importance of personnel performance in the workplace and in the production process, companies can greatly improve product quality and improve when manufacturing products in a safer and more humane-oriented environment. Work efficiency. Ergonomic simulation can tell engineers what workers can see and grasp, whether the work environment is friendly, where workers can be hurt, whether they feel "imper" or fatigue and other important ergonomic information.
Human body model libraries of different genders and sizes based on international standards can ensure that the station design is suitable for workers of all types. Users can design detailed, accurate and effective manual work. Human movements can be easily defined through different grip and walking macro commands.
(1) Artificial simulation
Determine the optimal sequence of operation for assembly and disassembly of the product. Through dynamic charts and chronological order, you can understand the feasibility and limitations of the assembly to determine the optimal sequence of operations.
(2) Detailed design of manual operation
In a virtual 3D environment, the collision between the human body and the environment is discovered, the scope of the analyst's work is ensured, the feasibility of the manual work is ensured, the human arm is reachable, and the worker's field of vision is displayed through a flexible configuration window, from the perspective of the worker. Complete the feasibility check of the operation, rationally design and optimize the manual operation.
(3) Ergonomic analysis
Manual operation is constrained according to ergonomic standards. By using ergonomic standard methods (such as NIOSH 81 and NIOSH 91), effective inspection of snatch and handling operations, analysis and calculation of maximum acceptance, OWAS (Ovako Work Attitude Analysis System) method can perform work posture analysis.
(4) Working hours analysis
The execution time of manual operations can be determined by means of a recognized raw data sheet published by MTM. Users can rearrange the work stations through working and ergonomic analysis to make the operation more comfortable and efficient.
In addition to assembly operations, ergonomic simulation is widely used in a variety of development processes. The advanced virtual reality system can provide a virtual feeling space, and the user seems to be in it. Coupled with helmet-mounted displays, position trackers, data gloves and other input devices, participants create an immersive, dedicated, and immersive feel. In the early days of development, R&D personnel were able to get an Immersive experience before real products. It plays an important role in performance verification of products such as tanks, airplanes, ships, etc., training of operators and adaptation of the battlefield environment.
Ergonomics simulations are often used to solve problems such as achievability, posture, lift, and tempo, as well as in the development of operational guidelines, the preparation of working hours quotas, and compliance with labor insurance regulations. Recent developments have brought him into a wider range of applications. In the development of some complex products, the development and identification of major projects, the individual or team of operators are placed in large scenes and complex environments, and they complete the entire operation of a series of complex actions in coordination with each other. For example, in the military, in the process of dismantling, repairing, and reinstalling the ship-borne aircraft engine, the maintenance team must complete the complicated work process as soon as possible under the operational conditions under the constraints of the small space on the ship and the complex environment inside the ship. And meet strict quality requirements.
Conclusion
It is our national policy to transform traditional industries with information technology, use industrialization to drive industrialization, and achieve leap-forward development. More and more manufacturing companies have carefully planned and actively constructed the enterprise information system integration framework from the perspective of long-term development strategy, laying the foundation for deepening enterprise information sharing and promoting enterprise innovation. The traditional manufacturing industry, especially the equipment manufacturing industry, with the digital manufacturing platform supported by PLM strategy, will add new vitality to enterprise innovation.
