摘要:
基于SCHENCK整车道路模拟试验台,设计和实施了AD250铰接式自卸车整车道路模拟试验.采用路谱激励模拟车辆实际行驶状态,在不同路面、载荷与车速下,以加权加速度均方根值为指标评价了AD250铰接式自卸车的平顺性.分析了前后悬架橡胶弹簧上下测点加速度响应的频谱特性,掌握了不同载荷工况下前后橡胶悬架系统的非线性动态特性.试验表明:该车平顺性有待于进一步提高,前悬架对于隔离来自路面的激励起到了一定的作用,而后悬架没有起到有效的隔振作用.该研究为检验和修正整车动力学模型及悬架系统优化设计提供了重要依据.
Abstract:
Road simulation experiment of AD250 articulated dump truck was designed and implemented on SCHENCK road simulation test bench. Using road excitation to simulate the status of practical running on different roads and at different velocities, the ride comfort of the truck was evaluated according to root mean square(RMS)acceleration under different running status. The nonlinear dynamics properties of front and rear rubber suspension were comprehended by analyzing the acceleration spectra at the upper and lower point of rubber spring under different loads. The test shows that the ride comfort of the vehicle needs further improvement. The front suspension can isolate the excitation from road; however the rear suspension does not provide positive effect. This study provides an important reference for verifying and correcting the whole vehicle dynamical model and the optimization of the suspension system.
