A truck frame fatigue life forecast based on virtual prototype technology Qiang Li1,2 1Shandong Transport Vocational College, Shandong Weifang, 261206, China; 2School of Transportation Science and Engineering, Beihang University, Beijing, 100191, China; ljzylq@126.com Keywords: frame, fatigue failure, alternating load, Finite Element Analysis（FEA） Abstract.
Frame material is 16Mn steel, the conventional mechanical performance as follows:Yield strength is 345 MPa, poisson's ratio is 0.3, the elastic modulus is 20600 MPa.
Use of these two parameters, considering the frame parts fatigue notch coefficient, size coefficient, surface quality factor,the S-N curve of frame material was modificated [7].

Results indicate that storage cost of raw materials and finished goods, at 58.35% of the total systemwide cost, is largest and most important.
The main raw materials of the latex industry are latex, chemicals and packaging materials.
(38.41 d.) 4.3 Problem analysis and proposed countermeasures From earlier results shown in Table 1, the largest percentage, at 58.35% of the total systemwide cost, is the storage cost of raw materials and concentrated latex.
Rubber industry is unavoidably subjected to high uncertainty due to seasonal harvesting natures of the raw materials, thus it is difficult to regulate the price.
Countermeasures to eliminate wastes Labor cost of sub collectors (30.77%) Storage cost of raw materials and concentrated latex (58.35%) Field latex collecting point design Forecasting technique(s) Fig.3.
