The goal of the Sustainable Painting Operations for the Total Army (SPOTA) program is to significantly reduce the amount of hazardous air pollutant (HAP) emissions produced in coating operations, including adhesives application and removal. Adhesives and sealants account for approximately 5of U.S. Army-wide HAP emissions from surface coating operations. Materials conforming to Federal specification MMM-A-121 have been identified as one of the largest contributors. The purpose of this research is to demonstrate and validate the HAP-free alternative adhesive 3M-847 in place of the baseline materials 3M-1357, Clifton E-1293, and 3M-1300L adhesive for specification MMM- A-121. Based on 2003 data, switching from the baseline adhesives to the alternative 3M-847 would mean an Army-wide reduction of over 1000 lb/year of HAP emissions. This report summarizes the methods for successfully field testing adhesive on an aviation helmet (model no. HGU-56/P) edge beading preventative maintenance/repair and a U.S. Army UH-60 Black Hawk helicopter nose door seal, conducted at Lowe Army Heliport, Fort Rucker, AL. An additional field trial was conducted at Anniston Army Depot, AL, on a Stryker infantry carrier vehicle driver s access hatch seal with successful results. In particular, technicians found that processing the alternative adhesives was similar to that of the baseline, and after 6 months, the adhesive did not have any signs of blistering, delamination (either cohesively or adhesively), substrate failure, or deterioration of any kind. Overall, the HAP-free 3M-847 adhesive was qualified for use on MMM-A-121 requisite substrates, such as vulcanized rubber (styrene-butadiene rubber, neoprene, and nitrile) bonded to unpolished steel, in addition to alternative substrates, such as silicone rubber and lightweight composite materials, showing a high versatility to the 3M-847 adhesive.

This paper presents an experimental study of the performance of a single track device driving on dry, granular soils. A single-track test rig is used to empirically investigate track motion under controlled track slip and loading conditions on three natural dry granular materials:a dry sandy material with 100 um average grain size, a dry sandy material with 400 um average grain size, and a coarse gravel with 1 cm average particle size. Test conditions can be designed to replicate typical field scenarios for lightweight robots, while key operational parameters such as drawbar force, torque, and sinkage are measured. This test rig enables imposition of velocities, or application of loads, to interchangeable running gears within a confined soil bin of dimensions 1.5 m long, 0.7 m wide, and 0.4 m deep. The tested single track device has an effective contact area measuring approximately 25 cm x 10 cm and it is tested under three vertical loads 125 N, 155 N, and 190 N. Slip is varied within -50and +50during travel over the three soils. The track utilizes a flexible rubber belt equipped with 0.5 cm tall grousers. Experimental measurements are compared against well-established semi-empirical models, to assess the predictive accuracy of these models.

前4个月，物流与生产资料市场运行基本平稳、结构优化。一方面，市场规模增速稳中小幅回落，但保持较快增长；另一方面，在增速回落的同时，市场结构向好转变、流通方式加快转型。当前经济运行中值得关注的问题，主要表现在两个方面：一是宏观层面上，投资需求偏弱;二是微观层面上，企业资金紧张、应收账款大幅上升。此外，企业经营面临的政策环境有待进一步优化。从后期走势看, PMI 指数连续两个月小幅回升，市场需求有所改善，生产资料市场价格呈现出趋稳走势，显示出宏观经济运行积极向好发展具有一定的基础。在此背景下, 行业保持平稳运行仍具备有利条件。

The Savannah River Site (SRS) is storing plutonium (Pu) materials in the K-Area Materials Storage (KAMS) facility. The Pu materials were packaged according to the DOE-STD-3013 standard and shipped to the SRS in Type B 9975 packages. The robust 9975 shipping package was not designed for long-term product storage, but it is a specified part of the storage configuration and the KAMS facility safety basis credits the 9975 design with containment. Within the 9975 package, nested stainless steel containment vessels are closed with dual O-ring seals based on Viton GLT or GLT-S fluoroelastomer. The aging behavior of the O-ring compounds is being studied to provide the facility with advanced notice of nonconformance and to develop life prediction models. A combination of field surveillance, leak testing of surrogate fixtures aged at bounding service temperatures, and accelerated-aging methodologies based on compression stress-relaxation and oxygen consumption analysis is being used to evaluate seal performance. A summary of the surveillance program relative to seal aging behavior is presented.

针对聚对苯二甲酸乙二酯(PET)吹塑模型腔曲面精加工表面质量要求，为减少抛光作业工作量，提高型腔零件制造效率，通过高速铣削实验分析1.2085葛利兹模具钢精加工表面粗糙度(Ra)随切削参数的变化规律。结果表明，PET吹塑模型腔零件常用的1.2085葛利兹模具钢在200～300 m/min的高速加工速度区间，Ra随切削速度(Vc)变化无单调增减规律，但选择偏小的径向切削深度(ae)和每齿进给量(fz)获得的Ra亦小，当轴向切削深度(ap)选择在0.05～0.25 mm之间时，ap=0.15 mm获得的Ra值最小。各切削参数对Ra的影响顺序为：ap＞ae＞Vc＞fz。
