Fatigue Life Analysis of Vehicle Frame Based on Adams/ncode
The frame,as the main load-bearing part of the mine car,bears the load from the freight car and the car-go,and transmits the load to the bridge and the ground through the suspension system,the uneven ground will feed the load to the frame through the tire and suspension system,which results in the complex stress situation of the frame,the failure form of the frame not only has the static strength failure,but also has the fatigue failure.The whole vehicle dy-namic model is established by Adams to select the stress points of suspension and frame,establish the road conditions and output the whole vehicle load spectrum.In the life analysis software ncode,combined with the finite element software ANSYS,the static analysis of the vehicle frame under three working conditions is carried out.
