| Abstract: | The hookup of carriage motor worked by the exciting of roadway and caterpillar track.The maneuverability is affected by great vibration. According to the data of roadway frequency, the author establishes the relationship between exciting frequency and carriage motor speed.Using the method of mode analysis,the author analyses the hookup on the way of finite element, and gives the dynamic characteristic of hookup.And the reasonable speed is presented according to the condition of pneventing carriage motor from resonating. |
