Reliability And The Threaded Coupling Elastoplastic Finite Element Analysis Of Accumulator Of A Vehicle

In this paper, Qinghai tie grind road test section construction, tunnel blasting spoil explore the physical properties abandoned stone structure, its ability to analyze after some processing to be applied to the subgrade filling in. In specific aspects of the construction process of the roadbed, paving leveling method for research, rolling-parameter selection, research RCC combination of subgrade compaction quality control and other discussion to discuss the possible construction of Qinghai rolling mill road sex, other mountain stone embankment to provide a reference. Before this test section construction, the first application of finite element analysis, research embankment static load deformation under the effect of the forces on the roadbed slope to explore, while research subgrade settlement in static load changes under the action in respect different overlay positions, different combinations of rolling acting on the roadbed, subgrade settlement changes, then discuss suitable for rolling different combinations overlay position from the theoretical point of view, the final analysis by field compaction tests and theoretical comparison recommend suitable rolling different combinations ply position. At the same time, carry out laboratory experiments determined that the tunnel spoil, abandoned stone properties are also discussed whether for roadbed construction, according to the nature of the mixture can be applied to re-design the construction of construction grading. In particular in the first test section of the foundation bearing capacity test, research in high altitude alpine region can roadbed filling, can filling tall embankment, and then paving the way roadbed construction, leveling technology to explore, conduct pressure before the real test combination, the first for a stand-alone test comparison, and then follow the recommendation of the finite element analysis before compaction combinations tested before compaction recommended combination to verify, to discuss the process of rolling compaction combinations. Then focus on the study of the entire construction process, the first step of construction machinery and discuss different ways of supporting the selection, and then on the entire construction process, construction machinery and equipment research and coordination at work, trying to get the economy in the pursuit to achieve the construction requirements of the situation benefit. Finally reasonable compaction quality testing and control of construction site-specific circumstances.
