IEEE TRO发表！华科团队打造仿生隔振 + 负载调控的“双减压”悬浮背包，破解越野负重痛点

Core Viewpoint - The article discusses the development of an active suspension backpack system that integrates wearable technology and active control mechanisms to reduce load impact and enhance user comfort and metabolic efficiency during long-distance walking and outdoor activities [1][4]. Group 1: Active Suspension Backpack Development - The active suspension backpack system is designed to dynamically adjust the load distribution between the shoulders and waist, alleviating shoulder pressure and improving metabolic efficiency [3][4]. - The design is inspired by biological mechanisms, particularly the load distribution observed in long-legged birds, which allows for better stability and vibration damping in complex terrains [3][14]. - The system incorporates a dual-support structure that redistributes load from the shoulders to the waist, significantly reducing shoulder strain [7][8]. Group 2: Performance Testing and Results - Systematic experiments were conducted to validate the performance of the active suspension backpack across various terrains, showing an average metabolic efficiency improvement of 18.68% on flat ground, 9.58% on stairs, and 12.35% in complex terrains [4][21][24]. - In flat ground tests, shoulder pressure was reduced by an average of 45.7%, with peak shoulder pressure decreasing by 46.6% and maximum load acceleration reduced by 72.7% [21]. - During stair climbing, shoulder pressure was reduced by 44.6% on average, with peak pressure decreasing by 48.4% and maximum load acceleration reduced by 55.5% [23]. - In complex terrain tests, shoulder pressure was reduced by 36.6% on average, with peak pressure decreasing by 38% and maximum load acceleration reduced by 44.6% [24]. Group 3: Future Prospects - The research team aims to further enhance the active suspension backpack's intelligent perception and adaptive control capabilities, focusing on dynamic load adjustment and endurance for high-intensity tasks in military, emergency rescue, and outdoor exploration scenarios [29].
