以道路试验数据为激励和验证信号,从2个方面提高驾驶室的振动舒适性：驾驶室结构方面,在HYPERMESH中对其进行了结构优化,在ADAMS中对结构优化前后的驾驶室振动舒适性进行了量化对比,结构优化后,不同车速下,驾驶员座椅处加权加速度均方根值平均降低6%;驾驶室悬置方面,利用柔性化的驾驶室建立其悬置系统的多体动力学模型,以加权加速度均方根值为优化目标,在频域内对悬置的刚度和阻尼进行了正交试验优化,在时域内对优化前后悬置的动挠度进行了对比,悬置优化后,不同车速下,驾驶室员座椅处加权加速度均方根值平均降低10%,悬置动挠度平均降低21%。

英文摘要：

The vibration comfort of commercial vehicle is improved in two ways where the data for test are used as excitation and validation signals. The cab structure is optimized in HYPERM different speeds, acceleration RMS of the driver＇s seat is reduced by 6% on average compared previous structure in ADAMS. In terms of the cab suspension, a multi-body dynamics model flexible cab is built. Taking the acceleration RMS as the evaluation target, the orthogonal optimizing the stiffness and damping of the suspension is conducted in the frequency domain. The dynamic deflections are compared in time domain.. At different speeds,acceleration RMS of the dri is reduced by 10% on average after optimization of the cab suspension, dynamic deflection is re 21% on average. the road- ESH. At with the based on test for different ver＇s seat dueed by
