Have you heard about the driverless car developed by Google or Tesla? This one suggests that the day that the day when autonomous vehicles will be driving on our highways is not so far away. Robotization is everywhere is present everywhere and new technologies are available and available and implemented in various fields. The automated driving of industrial work vehicles is no exception. There has been a lot of progress in this field in recent years and already some sectors, such as sectors, such as agriculture and mining, have followed suit and and mining, have followed suit and deployed vehicles capable of performing a range of tasks on their own. FPInnovations is also interested the subject and a team of researchers is studying options for the options for the forestry sector.
Avez-vous entendu parler de la voiture sans conducteur développée par Google ou par Tesla? Celle-ci laisse présager que le jour où des véhicules autonomes circuleront sur nos autoroutes n’est pas si loin. La robotisation est présente partout et de nouvelles technologies sont disponibles et implantées dans différents domaines. La conduite automatisée de véhicules de travail industriels ne fait pas exception. Il y a eu beaucoup de progrès dans ce domaine ces dernières années et déjà certains secteurs, comme l’agriculture et les mines, ont emboîté le pas et déployé des véhicules capables d’exécuter seuls un ensemble de tâches. FPInnovations s’intéresse également au sujet et une équipe de chercheurs étudie les options pour le secteur forestier.
In early 1997, FERIC performed an operational evaluation of five onboard weigh scales for semi-trailers. The purpose of the study was to assess the scales in the field under normal operating conditions and as used by the drivers. The scales were based on load cells, pneumatic devices, or combinations thereof, and were intended for uses with either leaf-spring or air suspensions. Data were collected on the ease of use of the scales, their accuracies, and their short-term reliability, and were used to assess the suitability of the scales for in-woods use. The study found that four of the scales were consistently with the tolerance (1500 kg) accepted by the Ministère des Transports du Québec, which served as a reference.
We tested six plant species or mixes at Vegreville, Alberta to determine their ignition and fire behaviour characteristics and whether they could be used along linear corridors to reduce the fire potential at strategic locations. Nine ignition trials over three years and one grass-fire burning into the test plots were completed to allow ranking of the species based on their characteristics. Three of the species were chosen for additional field studies: white clover, yarrow, and Plateau Rocky Mountain fescue.
Ten varieties of hybrid poplars from 7 year-old to 30 year-old plantations were evaluated for OSB production. The clones were chosen for their similarity with aspen as well as their impressive growth. Static bending tests on small solid wood speciments indicate that all poplar hybrids have lower modulus of rupture (MOR) and modulus of elasticity (MOE) than aspen. Although the hybrid poplar varieties evaluated in this study generally had physical characteristics similar in aspen and the properties of the OSB panels made from them were good, manufacture of OSB using substantial quantities of hybrid poplar (i.e. 25% or more) will likely require adjustments to some processing steps.
