论文名称： The model analysis of mobile emergency platform car frame based on ANSYS   

摘要：Mobile emergency platform is the carrier of mechanical and electrical equipment. The car frame vibration would make mechanical and electrical equipment failure even damaged. Mobile emergency platform car frame can be considered as the elastic vibration system with many degrees of freedom. Modal analysis is used to analyze the car frame. It is shown that the first natural frequency is 15.153 Hz and the second natural frequency is 19.579 Hz, which is close to20 Hz that is generated by the excitation frequency . Resonance is ocuuered. Optimization design is used to design car frame.After optimization design the natural frequency of car frame avoid the excitation frequency. Emergency mobile platform is environmental emergencies emergency treatment equipment, which video and audio monitoring equipment, wireless communications equipment , sophisticated electronic equipment and instrumentation need are carried in. When transportation or work process, these equipments, especially data-receiving treatment equipment, communications data transmission control equipment, image processing service and other equipment, will be affected inevitably even be failure for the mechanical vibration of the engine and the uneven road. If the equipment is damaged, the entire mobile platform of paralysis will be occurred. Car frame of mobile emergency platform can be considered as the elastic vibration system with many degrees of freedom and vibration led directly to the equipment failure. It is necessary to make modal analysis for the car frame.
