Table 6 Workspace evaluation criterion and influence coefficient
From: A maintenance time prediction method considering ergonomics through virtual reality simulation
No | Workspace description | r | Workspace level | Influence coefficient |
|---|---|---|---|---|
1 | Arm and tools of the maintenance personnel have enough workspace in the natural condition, is convenient to complete maintenance operations | >1.8 | Good | 1 |
2 | Maintenance personnel’s arm and tool seldom collide the surrounding equipment, adjusting within a certain permitted scope, is convenient to complete maintenance operations | 1.5 < r < 1.8 | Normal | 1.1 |
3 | Arm and tool still cannot avoid colliding the surrounding equipment within a certain permitted scope, is difficult to finish the maintenance operation | <1.5 | Bad | 2 |
