Laminated wooden heavy equipment mats (HEMs) are increasingly being used at conventional construction sites such as roads and power lines, and in swampy/marshy areas as logging decks and helicopter pads due to growing stringency and enforcement of environmental regulations. Wood is an ideal material to be used in making HEMs because of its light weight, impact absorption ability and low cost. The substantial increase in demand, especially in western Canada, for wooden HEMs has attracted the attention of wood product producers in Atlantic Canada. Truall Inc., in Grand Falls, New Brunswick, is interested in manufacturing and supplying wooden HEMs to natural resources, energy and construction industries across Canada. These HEMs are made of the wood species native to eastern Canada. This project will investigate the potential use of shorter lumber (less than 20ft) and a few fastening patterns in fabrication of HEMs. The specific objective of this project is to identify fastening patterns and eastern wood species that will have potential in fabrication of HEM in the short term. In the longer term the technical information to be generated in this project will assist in the design of a future research project that will lead to an engineering design approach to wooden HEMs marketed by Truall Inc. To achieve the project objective, the project will be conducted using a combination of experimental and finite element modelling work. 3-ft wide and 20-ft long strip HEM specimens will be fabricated to verify the optimal configuration of HEM identified from finite element analysis. The developed product design, incorporating alternative wood species available in Atlantic Canada, use of lumber with shorter length and strategic fastening patterns will be forwarded to Truall Inc., which would revolutionize the HEM industry. No doubt, the increased demand for HEMs in the resource, construction and energy sectors will generate tremendous business opportunities for Truall across Canada.

在常规建筑中越来越多地使用层压的木制重型设备垫（HEMS） 诸如道路和电力线等地点，以及由于沼泽/沼泽地的登山甲板和直升机垫， 越来越严格和对环境法规的执行。木材是用于使用的理想材料 由于重量轻，撞击吸收能力和低成本而造成下摆。大幅增加 需求，尤其是在加拿大西部的木制下摆引起了木材产品的注意 加拿大大西洋的生产商。新不伦瑞克省大瀑布市的Truall Inc.对制造业感兴趣 向整个加拿大的自然资源，能源和建筑业提供木制下摆。这些下摆 由加拿大东部的木材制成。该项目将调查较短的潜在用途 木材（小于20英尺）和下摆制造中的一些固定模式。这个的具体目标 项目是识别固定模式和东部木材，这些物种可能在制造下摆有潜力 在短期内。从长远来看，本项目中要生成的技术信息将有助于 未来的研究项目的设计，该项目将导致木制销售的工程设计方法 Truall Inc.为了实现项目目标，将使用 实验和有限元建模工作。 3英尺宽和20英尺的长条状标本将是 制造以验证从有限元分析中鉴定出的下摆的最佳构型。发达的 产品设计，结合了加拿大大西洋的替代木材，将木材与较短 长度和战略固定模式将转发给Truall Inc.，这将彻底改变下摆 行业。毫无疑问，资源，建筑和能源部门对下摆的需求不断增加 在加拿大为Truall带来巨大的商机。
