Aiming at the safety problem existing in the driving of the multi axle electrohydraulic steering system,taking the electrohydraulic steering system of a sixaxle allterrain crane as example,the defects of the existing technology were analyzed,and an optimal design scheme of multiaxle electrohydraulic steering system was put forward according to the design concept of group control and redundancy.The test results show that the optimal design scheme can be used to effectively solve the steering safety accidents caused by component failures.It provides reference for the design of multiaxial electrohydraulic steering system.
