In Situ Determination Of Bottom Trawl Ground Gear Contact [PDF]
, 2001 No abstracts are to be cited without prior reference to the author.Exact definition of towed distance with proper ground gear contact is an essential parameter in bottom trawl swept area estimates of fish abundance. Errors in this key parameter may lead to a first order bias in abundance estimates of demersal fish.

Effect of ground gear modification on bycatch of rays in mediterranean bottom trawl fishery
Ocean & Coastal Management, 2022 Bycatch of rays and skates in towed fishing gears represents one of the major threats to these relatively slow-growing marine species. The objective of this study was to modify ground gear in a bottom trawl fishery to increase the escape of these species during towing without associated loss of target catch.

Six-wheel trolley type landing gear ground load analysis study
Xibei Gongye Daxue Xuebao, 2022 为了分析起落架支柱柔性和机身柔性对飞机地面运动载荷的影响, 应用动力学基本原理, 建立了六轮小车式起落架动力学模型及全机模型。对活塞杆与外筒柔性化处理, 并在对称水平着陆、机尾下沉着陆和滚转着陆3种着陆工况下, 分析了小车式起落架的载荷分配情况, 研究了着陆工况及支柱柔度对小车式起落架载荷分配的影响。对机身进行柔性化处理, 分析机身柔性对地面载荷的影响。结果表明: 支柱柔度对起落架航向载荷影响较大, 对垂向载荷影响较小; 考虑机身柔性后, 弹性机身变形吸收能量, 有助于减弱机体振动 ...
