摘要
Abstract
This research aims at developing a portable and intelligent lightweight dynamic penetration device to replace the cur-rent manual penetration equipment.The R&D focus on solving three problems:1)To realize the free fall movement of the falling hammer,it is necessary to exclude any structure and parts from contacting the falling hammer.Electromagnets are used to adsorb and release the falling hammer,and then completely separate from it so as not to affect its free fall.2)Sensor-controlled method is applied to accurately control the hammer's drop within the 500 mm drop distance.3)The drop weight of the light dynamic pen-etration test is 10 kg,and the potential energy of the drop weight is relatively large when lifted and released.And the stable large chassis and tripod structure increase the stability of the whole equipment.关键词
