STABILITY ANALYSIS OF WATER QUALITY MONITORING VEHICLE
Keywords:
Water quality monitoring vehicle, Chassis modification, Load distribution, Driving stabilityAbstract
This study takes the water quality monitoring vehicle refitted from the Ford V363 four-wheel drive chassis as the research subject. Aiming at potential safety hazards caused by changes in vehicle load and gravity center after equipment installation, vehicle load characteristics and driving stability are comprehensively investigated. The mass moment method is adopted to conduct load calculation and layout optimization. The optimized axle load and gravity center parameters fully comply with the requirements specified in GB 7258-2017, and the relative deviation between experimental measurements and theoretical calculations is less than 0.3%. Vehicle dynamic theories are applied to calculate key indicators including roll stability angle and braking offset. All tested stability indicators satisfy relevant national standards, with the maximum relative error between experimental and theoretical results limited to 3.8%. The results verify that the proposed modification scheme is safe and feasible. The modified vehicle can operate reliably under diverse complex working conditions, and the research findings can provide technical references for the design of similar refitted special vehicles.References
