摘　　要：本研究在气压阻效应、密封条、车门铰链、车门限位器、车门重量以及车门门锁等6个方面分析了影响乘用车车门关闭能量因素。利用建立了不同影响因素下的关闭能量的数学模型与MATLAB提供的GUI平台,开发一种便于计算关闭能量的工具,用于计算各影响因素的关闭能量贡献值。通过实物试验,得到各影响因素的试验贡献值,对比试验结果与计算结果,偏差在15%内,在允许误差范围。该工具具有较强的交互性,有助于提高车门质量的各类设计。This research starts from six factors(air pressure effect,sealing strip,door hinge,door stopper,door weight,and door lock) that affect the closing energy of passenger car doors,and establishes a mathematical model of closing energy for different influencing factors.Based on the established mathematical model and the GUI platform provided by MATLAB,a tool for calculating the closing energy is developed to calculate the closing energy contribution value of each influencing factor.At the same time,through the physical test,the test closing energy contribution value of each influencing factor is obtained,and the coMParison of the test result and the calculated result shows that the deviation is within 15%,which is within the specified range.This tool is highly interactive for researchers and helps improve the quality of car door design.
