中间位置转向试验与半挂牵引车操纵稳定性

Central Steering Tests and Handling Quality of Semitrailer Tractors

根据半挂牵引车的特点,引入并修改了国外广泛应用的中间位置转向操纵稳定性试验方法,介绍了对试验结果的评价方法,并结合某国产牵引车和Scania360型牵引车进行了试验验证。通过试验发现,国产牵引车在路感、转向响应等方面都需进行改进;该试验方法在半挂牵引车操纵稳定性试验中应用是可行的。

In terms of features of semitrailer tractors,the central steering handling quality test method widely used in foreign countries is introduced and modified,The evaluation method for test results is introduced and is verified with tests of a domestic tractor and a Scania 360 tractor.It is found that the domestic tractor should be improved on road sense and steering response ;the test method is viable for semitrailer tractor handling quality tests.
