In this paper , three kinds of static test operations are given such as the shovel descended with the front - end of the bulldozer lifted , the ridger descended with the rear - end of the bulldozer lifted , the shovel and the ridger descended with the whole body of the bulldozer lifted the static tests for the frame of ty220 bulldozer are proceeded . the result of finite element analysis is contrasted with that of experiment the mechanical model and the result of finite clement analvsis are verified by experiment and the theoretical bases are provided for the improving design of frames 4 according to the results of calculations and tests , the suggestion is presented for improving the design of the frame of ty220 bulldozer
给出了铲刀下移推土机前端抬起，松土器下移推土机所端抬起，铲刀、松土器同时下移推土机整机抬起等三种静态试验工况，对推土机台车架进行了静态试验，并将实验结果与有限元计算结果进行了比较，验证了力学模型及有限元分析结果的正确性，为台车架的设计提供了一定的理论依据。
