متن کاملComparative Research on Optimal Damping Matching of Seat System for an off-Highway Dump Truck
To protect the driver of off-highway dump trucks from the harmful vibration, this paper presents the comparison results to determine the optimal damping of the seat system by different optimization design plans. Three optimization schemes are considered including individually optimizing the damping of the cushion, individually optimizing the damping of the seat suspension, and integrately optim...
متن کاملThe Effect of Trifluralin on Rhizoctonia solani (isolate AG4), Causal Agent of Soybean Damping off
Damping off caused by Rhizoctonia solani (isolate AG4) constrains growing soybean in the north Iranian province of Golestan. The pathogen was grown on malt agar containing 0, 50, 100 or 200 ppm trifluralin then its vegetative growth and virulence were evaluated. The response of soybean cv. Williams seedlings grown in soil containing 0, 0.5, 1 and 2 ?g ai g-1 trifluralin was investigated. On mal...
