| 摘 要： | 根据直线连接耦合损耗因子的计算理论,推导出了折线连接、弧线连接、任意曲线连接耦合损耗因子的计算公式。通过数值仿真,建立了直线连接、折线连接、弧线连接和任意曲线连接耦合系统模型,并对这4种形式连接的耦合损耗因子进行了数值计算。建立了轿车统计能量分析模型,并对轿车各个相邻子系统进行耦合,算出了轿车各子系统间线连接耦合损耗因子。

| Abstract: | According to the calculation theory of the coupling loss factor( CLF) of the straight-line junction, the calculation formulas were deduced for the CLFs of the broken-line junction,arc junction and arbitrary curve junction. Models were established by numerical simulation for the coupling systems of the straight-line junction,the broken-line junction,the arc junction and the arbitrary curve junction,and the CLFs were computed for these 4 kinds of junction. A statistical energy analysis( SEA) model was built for a car,the adjacent subsystems of the car SEA model were coupled,and the CLF of the line junction between subsystems of the car were calculated. |
