The TY Dump Truck Design and Analysis of Frame Dynamic Characteristics

The dynamic analysis of a new frame structure based on weight reduction and lowering the center of gravity was carried out.The original frame modal analysis was compared with the results of the finite element modal and modal test to verify the effectiveness of the finite element modeling approach after the three dimensional modeling and the finite element modeling based on the modal test.Then it carried on the same method to establish a new frame finite element model and by contrasting modal characteristics of the original frame and the new frame and combining engine and road excitation to evaluate the dynamic performance of the new frame.The analysis shows that the dynamic characteristics of the new frame is better than the original frame structure,which verifies the credibility of the improved design and provides reference and basis for the trial design and improvements of the new frame.
