Design and Optimization of Dynamic Power Take-Off for Multifunctional Fire Engine
This paper takes the multi-functional power output system of high-power fire engine as the research object,a dynamic power take-off is designed,and the power take-off is optimized and analyzed.Firstly,the overall design of the power take-off is carried out,and the three-dimensional digital modeling of important parts is carried out.Then the finite element analsis method is used to analyze the strength and steady-state heat dissipation of main parts.Finally,the structural design is optimized,the first order natural frequency of the box is 282.21 Hz,which is 12.69 Hz lower than that before optimization,and far higher than the external excitation of the transmission and oil pump.Therefore,the improved box structure of the power take-off still meets the dynamic characteristics,which ensures the power,economy and reliability of the power take-off.
