Dynamics Analysis And Vibration Control Research Based On Fire Truck Boom

In this paper，the research object is elevating platform fire truck’boom ofzoomlion，this arm frame size is huge and have high flexibility，this feature of theboom triggers the two research difficulties：first of all，boom’size is huge and itsposture is various，if we conduct a test for modal parameter identification or otherdynamics analysis，this experiment will cost us lots of time，some experiment wouldbe hard to be planed and put into effect。this situation required us to put forword anew scheme to save the waste of time，improving the work efficiency。and then，wecan not ignore the flexibility of the boom in the process of research，the boom willshow some deformation that we can not ignore in the time of that the boom ismoving，the deformation will affect the stability of the boom and bring safe hiddentrouble to the operator on the work platform。boom’deformation especially thedeformation on the end of the boom would be our research emphasis。this paper conduct the work around these problems，Dynamic analysis wascarried out to the boom based on the Finite Element Method and establishing a Rigid—Flex Hybrid modeling，putting forward a quick and efficient solution of modalparameter identification based on the Response Surface Method。Based on the resultof the Dynamic analysis，I conduct a research about the control of the instability of thework platform on the end of the boom in the braking process。The result show us thatthe plan based on the Response Surface Method in the work of modal parameteridentification is effective and feasible。the control technique of the instability of thework platform in the braking process is effective and feasible。...
