Abstract

The vibration tests were carried out using a 162kW wheeled tractor to evaluate the Whole-body vibration while the tractor working in the field, driving on concrete road and in-parking state. The tractor ride comfort was analyzed using the joint weighted acceleration of seat surface vibration from 1 to 80 Hz as the evaluation indicator, according to ISO2631 standard suggestions. During field work, the combined acceleration of the driver’s whole body vibration is 1.39, and the subjective feeling is extremely uncomfortable. Based on the multi-body dynamics analysis software, a tractor dynamics simulation model including the seat, cab mounts, chassis, tyre and road coupling system was established. By changing the model parameters, the influence of the tractor driver’s whole body vibration under the condition of the artificial test track was further analyzed. The analysis shows that the factors that have a greater impact on the driver’s whole body vibration when driving on the artificial runway are the vertical stiffness of the tyre, the vertical stiffness of the seat suspension, and the damping coefficient of the tyre.

建立了影响162kW轮式拖拉机驾驶员全身振动主要因素的优化模型

采用162kW轮式拖拉机进行了振动试验，评估了拖拉机在田间工作、混凝土路面行驶和停车状态下的全身振动。根据ISO2631标准建议，以1 ~ 80hz的座椅表面振动关节加权加速度作为评价指标，对拖拉机的平顺性进行了分析。在野外作业时，驾驶员全身振动的综合加速度为1.39，主观感觉极不舒服。基于多体动力学分析软件，建立了拖拉机座椅、驾驶室支架、底盘、轮胎和路面耦合系统的动力学仿真模型。通过改变模型参数，进一步分析了人工试验轨道条件下牵引车驾驶员全身振动的影响。分析表明，在人工跑道上行驶时，对驾驶员全身振动影响较大的因素是轮胎的垂直刚度、座椅悬架的垂直刚度和轮胎的阻尼系数。
