Effect of speed on the accuracy of stress-grading machines for lumber
Summary A computer simulation model is developed for predicting modulus of elasticity (E) of uniform lumber measured at high speed by stress-grading machines of the constant-deflection type. Simulations carried out with the model showed that speed had no significant effect on the average E measured...

| 520 | |a Summary A computer simulation model is developed for predicting modulus of elasticity (E) of uniform lumber measured at high speed by stress-grading machines of the constant-deflection type. Simulations carried out with the model showed that speed had no significant effect on the average E measured along the lumber but largely affected E values measured at individual locations. Tests conducted at 15, 150 and 315 m/min with two machines employing different supports conditions confirmed model predictions. Ability of the grading machines to identify local E values at high speed could be improved by proper filtering of the load signal recorded by the machine. | ||

Effect of speed on the accuracy of stress-grading machines for lumber |
| abstract |
Summary A computer simulation model is developed for predicting modulus of elasticity (E) of uniform lumber measured at high speed by stress-grading machines of the constant-deflection type. Simulations carried out with the model showed that speed had no significant effect on the average E measured along the lumber but largely affected E values measured at individual locations. Tests conducted at 15, 150 and 315 m/min with two machines employing different supports conditions confirmed model predictions. Ability of the grading machines to identify local E values at high speed could be improved by proper filtering of the load signal recorded by the machine. © Springer-Verlag 1987 |
