To evaluate the bolt-connection reliability of the integrated aluminum alloy frame for commercial vehicles, this study adopts a systematic method including torque statistics after fatigue test, Brinell hardness test of mounting surfaces, ultimate torque verification test of threaded connection pairs, and anti-loosening test under road load spectrum. The results show that after 1.5×10⁵ cycles of sinusoidal fatigue loading, the residual-torque retention rates of all critical connection points are higher than 70%; the hardness of mounting surfaces ranges from 65 to 115 HBW with uneven distribution and an average value of about 86.5 HBW. The equivalent Brinell hardness is converted from test data obtained using an impact ball with a diameter of 3 mm and an impact energy of 11 mJ, and the connection point of the lower control arm has the lowest hardness; the safety factors for M12~M18 bolt connections are no less than 1.55; under road-load-spectrum loading, the maximum attenuation rates of torque and axial force are 15.3% and 14.9%, respectively.

为评价商用车铝合金一体化车架螺栓连接的可靠性，采用疲劳试验扭矩统计、安装面布氏硬度测试、螺纹连接副极限扭矩验证试验及道路载荷谱耐松动试验的系统方法开展研究。结果表明：1.5×10⁵次正弦疲劳载荷后关键连接点残余扭矩保持率均高于70%；安装面硬度为65~115 HBW，分布不均且均值约86.5 HBW，硬度测试冲击球直径3 mm、冲击能量11 mJ，经换算得到等效布氏硬度，下控制臂连接点硬度最低；M12~M18螺栓连接安全系数均不低于1.55；道路载荷谱下最大扭矩与轴向力衰减率分别为15.3%、14.9%。
