摘要

侧倾稳定性的优劣直接影响到轮式拖拉机的使用安全,采用虚拟样机技术研究轮式拖拉机的侧倾稳定性。应用三维建模软件UG建立轮式拖拉机实体模型,导入到Adams/VIEW虚拟环境下,按照相关标准,模拟轮式拖拉机静侧翻稳定性试验和前轮踏空稳定性试验。通过分析轮胎受力曲线判断拖拉机的最大侧翻稳定角,以此来衡量拖拉机的侧倾稳定性,并通过实车试验进行对比验证。前桥刚性联接和铰接时最大侧翻稳定角的误差分别是3.64%、0.98%,仿真结果与实车试验结果相比较误差较小,表明该虚拟模型精准度较高,仿真过程可靠。因此在轮式拖拉机研发过程中,应用虚拟样机技术可大大提高物理样机合格率,在一定程度上可取代实车试验,进而极大地缩短研发周期,减少设计成本,具有实用价值。

Abstract

The roll stability directly affectsthe wheeled tractor security. Virtual prototyping technology was used to study wheeled tractor roll stability. The precise model of the wheeled tractor was established with 3D modeling software UG. Then the model was introduced into ADAMS / VIEW to simulate the static rollover stability test and the front wheels by unbalance force test of wheeled tractor. The tire force curves were analyzed to determine the tractor maximum rollover stability angle,which was used to measure the tractor roll stability. Finally the simulationresult was verified by real vehicle test. The deviation between real vehicle test results and simulation results was very small. Sothe virtual model was accurate and the simulation was reliable.Application of virtual prototyping technology can greatly improve the qualified rate of physical prototypes in wheeled tractor development process. The simulation can replace the real vehicle test in a certain extent and has practical value.
