Show:
| Project | 95%-SAE human body | 50%-SAE human body |
| H point is to shoulder axis director's degree | 480 | 442 |
| Upper arm pivoting point distance | 376 | 334 |
| Human body upper arm lengths | 300 | 275 |
| Human body forearm lengths | 267 | 244 |
| Human body arm outside width | 485 | 431 |
| Elbow diameter | 90 | 90 |
| Two elbow sides are wide | 500 | 443 |
| Wrist to hold distance | 81 | 75 |
| 90 degree of bottoms of elbow arm are away from seat cushion height | 239 | 214 |
| R point is away from seat cushion height | 96 | 80 |

Position.Ball is drawn for radius to hold minimum point with 348, using the 95% human body point of shoulder point drawn in digital-to-analogue as the centre of sphere, with radius 300
Upper arm ball is drawn, the intersection of two balls is made.Leftmost side point is found with extremum method on two ball intersections, this point is wheel steering mistake
The elbow position ultra-left point being exposed at first when holding lowest order in journey, finds out the actual most left extreme point of ancon with this position, and
The ball for drawing radius 45 for the centre of sphere is put with this, the ultra-left point of ball is made with extremum method, this point is under human body ancon rotary state
Lower lateral extent human body seat R point three coordinate direction of maximum site, measure X of this site apart from human body seat R point to away from
From for 91mm, Y-direction distance 278.7mm, Z-direction distance is 324.4mm.
Step S3, S4 as above is obtained for 95%-SAE organization of human body information, is directed to 50%- in the same way
SAE organization of human body information, obtain step S3, S4 as a result, its result is as shown in the table:
Data obtain from table, elbow are touched when turning to for anti-door internal decoration plate, door internal decoration plate is away from steering wheel outside edge Y-direction before designing
Distance is not less than 154.9mm (95% human body), it is determined as 155mm, the first plaque 102 are not less than with human body seat R point Y-direction distance
347.5, it is determined as 348mm.
S5, in order to which the door internal decoration plate design met under the control of certain vehicle width should meet and height of seat and front and back adjustment
It is required that be not more than 279mm, therefore, Z-direction height of the table top 101 apart from human body seat R point cannot be greater than 279mm, and need to be in X
280mm or more is kept to human body seat R point distance, this boundary is not in the case where step interferes elbow.Therefore, in digital-to-analogue
On, do the extended planar namely Y plane that one extends in the vehicle width direction, and make Y plane apart from human body seat R point away from
From for 280mm, this plane and 95%-SAE human body and 50%-SAE human body upper arm ball intersection are made respectively, makes human body trunk line
Projection on this face finds out the intersection point of projection line Yu ball intersection respectively, measures this point at a distance from human body seat R point, and
Determining its Z-direction height, this height value is the maximum height of table top, as a result 95%-SAE human body step height is 180.3mm,
50%-SAE human body step height is 173.3mm, takes into account two kinds of human bodies, then daylight opening DLO human body seat R point height 173mm or more compares
It is appropriate.
