Dynamic behavior of nonuniform lumber in stress-grading machines
Summary A finite element model is developed to predict the dynamic behavior of nonuniform lumber in stress-grading machines of the constant deflection type. Simulations carried out with the model showed that speed largely effects the accuracy with which grading machines can identify low-point modulu...

| 520 | |a Summary A finite element model is developed to predict the dynamic behavior of nonuniform lumber in stress-grading machines of the constant deflection type. Simulations carried out with the model showed that speed largely effects the accuracy with which grading machines can identify low-point modulus of elasticity (E) oflumber. Tests conducted at 15 and 315 m/min on lumber members containing a low E zone confirmed model predictions. However, as demonstrated in this study, machine ability to detect low-point E at high speed can greatly be improved from filtering the load signal measured by the machine. | ||

Dynamic behavior of nonuniform lumber in stress-grading machines |
| abstract |
Summary A finite element model is developed to predict the dynamic behavior of nonuniform lumber in stress-grading machines of the constant deflection type. Simulations carried out with the model showed that speed largely effects the accuracy with which grading machines can identify low-point modulus of elasticity (E) oflumber. Tests conducted at 15 and 315 m/min on lumber members containing a low E zone confirmed model predictions. However, as demonstrated in this study, machine ability to detect low-point E at high speed can greatly be improved from filtering the load signal measured by the machine. © Springer-Verlag 1990 |
