The Fem Analysis And Optimization Design For The Compartment Of Sweeper

With the rapid development of the domestic economy and the gradually accelerating of urbanization,pollution of the city is also increasingly serious.At the same time,people’s appealing about the quality of environment is raising accordingly.Urban sanitation will play a more important role in the improvement of the urban environment,traditionally human-based cleaning job can no longer meet the needs of today’s social development,road sweeper and other mechanical sanitation equipment will be more and more favored by the market.As the main bearing part of the road sweeper,It has a great significance to carry out the finite element analysis and structural optimization for the compartment of the road sweeper,which is important for improving the quality and reducing the cost of vehicle production.The research is based on the compartment of the road sweeper which is cooperatively designed by a special vehicle factory in Hebei province and Hebei University Of Technology.Firstly,the three dimensional model and finite element model are established respectively by using 3D modeling software of UG6.0 and finite element analysis software of HyperWorks.Then make the analysis of static strength and stiffness and modal analysis of the compartment in the three typical conditions.Furthermore,according to the results of finite element analysis of the compartment,size optimization of compartment is built,and it was verified that the new compartment satisfying the design requirements of strength and stiffness after lighting the weight.Above all,the research meets the need of the design.A virtual prototype model for discharging process of compartment is established by using simulation software of ADAMS,then the kinematics simulation for discharging process of compartment is completed,The research result indicates that the maximum discharge angle and the angular velocity of compartment meet the design requirements.
