Abstract
The article demonstrates the results of the experimental estimate of the drawbar properties of the oversnow equipment during which parameters and indicators allowing for their use during designing of new generation of oversnow vehicles have been determined. This work demonstrates the results of the tests in determining maximum drawbar pull, determining motion resistance force with the arrested and released brake of the Russkaya Mekhanika’s oversnow vehicles, models RM Buran Leader, RM Tayga Varyag 550, RM Tayga Patrul 800 SWT, RM Vector 551i and over companies’ oversnow vehicles, models BRP Lynx Xtrim Commander 800 E-TEC, Arctic Cat Pantera 7000 XT LTD, Polaris 800 Titan Adventure 155.
Highlights
During the test: The test site was covered with compacted snow 5 to 7 cm deep, the snow was uniform along the entire depth, with a temperature of minus 6 °С
Weight measuring strain gauge С2-5.0-С3 and digital tension gauge ZET were used as measuring instruments to determine the oversnow drawbar properties including maximum drawbar pull and motion resistance force [4]
The maximum drawbar pull was determined for the Russkaya Mekhanika's oversnow vehicles, models RM Buran Leader, RM Tayga Varyag 550, RM Tayga Patrul 800 SWT, RM Vector 551i and over companies' oversnow vehicles, models BRP Lynx Xtrim Commander 800 E-TEC, Arctic Cat Pantera 7000 XT LTD, Polaris 800 Titan Adventure 155 equipped with caterpillar tracks with snow grip from 10 to 45.7 mm
Summary
The tests to determine drawbar properties of the oversnow equipment were conducted in vicinity of Rybinsk, Yaroslavl oblast, Russia at the horizontal terrain sections with the maximum slope of 1%. During the test: The test site was covered with compacted snow 5 to 7 cm deep, the snow was uniform along the entire depth, with a temperature of minus 6 °С. The tests were conducted in dry windless weather at an ambient temperature of minus 6 oС, atmospheric pressure of 748 mm Hg and air relative humidity of 86 % [1,2,3]
