In view of the airdrop adaptability of a lightweight high-mobility wheeled armored vehicle, the shock vibration of the vehicle’s onboard electronic equipment under simulated airdrop was tested and the shock characteristic of the equipment was analyzed. The test results show that the onboard equipment of the airdrop vehicle is mainly subjected to three stages of shock vibration, which includes the crash of the lifting rope, shock of the cushion airbag and the rebound shock. The cushion airbags can effectively reduce the shock acceleration peak of the onboard electronic equipment of the light wheeled armored vehicle, and the shock peak of the onboard computer and power supply is about 9-10 g with the shock duration of 0.15-0.2 s. While compared with the shock of the base, the buffering effect of the isolators to the airdrop shock vibration is not satisfied. Resonances of the isolation system are caused by the airdrop shock and the shock peaks of the tested electronic equipment are higher than that of the base.
Aiming at the poor ride comfort of an armored vehicle when driving on off-road, which affects badly the working efficiency of the crew members, the current standards of the ride comfort evaluation method were analyzed, and a comprehensive ride comfort evaluation method for multiple states was proposed considering different speed and road surface conditions. The experimental study on ride comfort of two vehicles was conducted. The test results show that vehicle #1 has better ride comfort performance compared with vehicle #2, and the proposed method can effectively guide the comprehensive evaluation of the ride comfort of armored vehicles, which is suitable for the comparative test of the ride comfort performance of armored vehicles.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
