Chassis is one of the key components of tracked test vehicle. The strength and rigidity of chassis must be considered and structure resonance should be avoided during the process of structure design. The stress nephogram and strain nephogram of chassis are obtained, after static analysis in the finite element analysis software ANSYS. The maximum stress is 65.13MPa and the maximum strain is 0.00032mm...
The pellet mill is widely used in many fields such as seed processing industry, new energy technology, pharmacy industry and so on. As we know, the ring die and the press roller are vital to the pellet mill. Therefore, a mechanical model is set up to describe the force which acts on the internal surface of the ring die. Based on the model, FEA is put up with ANSYS to obtain the axial stresses, the...
The simple, reliable and feasible finite element model with three-dimensional solid elements about blind hole bolt connection based on ANSYS is proposed to obtain bolt pre-tensional effect. It uses node coupling to simulate the connection effect of the thread and applies preload to the bolt in order to achieve pre-tensional effect by using the pretension elements in ANSYS. The FE model would be of...
Additional inertial force will cause the deformation of some parts when 3D-coordinate measuring machine (CMM) runs quickly. It will result in the difference between real results and reading of raster sensor, that is, dynamic error will be produced. This paper presents the theoretical model of CMM dynamic error compensation. The Z-direction deformation of crossbeam is analyzed based on Ansys, one kind...
