The controllability and stability test procedure for multi axle steering vehicle is still discussed. But the controllability and stability test proced ure for automobiles cannot be suitable to multi axle steering vehicle. It is very important to establish and perfect the controllability and stability test procedure for large scale multi axle steering vehicle. Based on the controllab il ity and stability test procedure for automobiles, the exploration test of a six axle steering vehicle controllability and stability has been done, which include the steady static circular test, pylon course slalom test and steering efforts test, and the test procedures have been set down. It lay a foundation for the method of multi axle steering vehicle controllability and stability test procedure.
