主 题：maize inter-rows intelligent chassis traction performance steering performance obstacle surmounting performance
摘 要：In view of the difficulties in weeding and plant protection in the middle and late period of maize planting,this paper proposed a self-propelled thermal fogger *** to the theoretical calculation and agronomic requirements for maize planting,the structure and working principles of the self-propelled thermal fogger chassis were *** this basis,the multi-body dynamics model of chassis structure was established,and the chassis traction,steering and obstacle surmounting performances were also *** the rationality and the feasibility of the design were verified through the furrow running test and test equipped with thermal *** results showed that,the traction performance improves with the decrease of soil deformation index and increase of cohesion,and when track pre-tensioning force was about 1000 N,the machine had a good traction performance;with the decrease of the soil deformation index and the increase of cohesive force,the stability of the single side brake turn of the chassis becomes better;on the contrary,with the increase of the tightness of the crawler,the steering radius turns smaller and the steering stability becomes *** heavy clay,with the pre-tensioning of 1000 N,the machine has better steering stability and smaller turning *** obstacle-surmounting simulation result shows that on sandy soil road,the maximum climbing angle for the chassis is 42°,the height of vertical obstacle crossing is 170 mm and the trench width is 440 *** study provides a reference for the design of plant protection machinery in the middle and late stages of maize planting.
