D35-type growth of goods vehicles clamp ears strength

The. Fourth, calculate the stress finishing hole bearing in mind the comparison with test results 1. Most of the units is the main stress of the order to verify the strength of the edge clamp ears, we selected the four conditions in the calculation of the two major stress condition of the unit order of its two principal stress conditions are: the vertical static and dynamic load conditions and vertical static and dynamic load Hejia lateral load case. Yun cut out sub-unit and rent the maximum principal stress shown in Figure 8, Table 1. 'Can be seen from the table, the maximum tensile stress side clamp ears 3l, Unit in place, the unit the maximum principal stress is 106.4MPa, the maximum pressure occurred in 55 units at the maximum principal stress as a 181.8MP8. Other elements are less than the value of stress. In addition, from 79 ~ 81,[link widoczny dla zalogowanych], the principal stress unit known as the cell position to hole distance increases, the stress quickly decay, the maximum stress occurs at the L side of the unit circle. *,[link widoczny dla zalogowanych], 6 'specifications according to strength, the stress is less than the ear clamp specifications set by the allowable stress value of rejection. Therefore, we can determine the strength of the department is adequate. 2. The results compared with the experimental results of four vehicles, according to the Institute, \cut the throat to the value for comparison in Table 2 and Table 3. Table 2 compares the two tests in all three strain gauges to the principal stress situation, Table 3 compares the strain gauge test one-way (along the ears tangential) stress situation. Not difficult to see from the Yuan,[link widoczny dla zalogowanych], although tests with the unit distribution point some distance from the centroid, the stress changes and the most stress occurs in dogs is very consistent at most of the results are close to fully explain ears load distribution and calculation is correct The. V. CONCLUSIONS (1) Based on the comparative analysis of several holes with the load axis and the treatment method, the elastic contact theory proposed a simple calculation based on 'The example shows, with the elastic contact theory to calculate the distribution of the maximum packet load angle, then press the cosine law of distribution of load rhyme is reasonable 'treatment project to be assisted method has been applied with the cutting and hole charge distribution problems can be relatively satisfied with the results.
