Supporting Plate

A constraint condition finite element analysis mode of the high speed PCB drilling machine Z-axis bottom plate was established on the platform of Abaqus. And then an optimal structural mode of a Z-axis supporting plate was obtained by means of performing constraint modal analysis and dynamic analysis optimization on the structure of the Z-axis supporting plate. modal tests and analyses were performed on the Z-axis plate before and after the optimization with the application of an LMS vibration/dynamic signal acquisition and analysis system. The experimental results were shown that the tested Z-axis plate dynamic characteristics were basically consistent with the obtained Z-axis supporting plate mode from simulation analyses using the finite element software Abaqus. It was proved that using the finite element software was feasible for optimizing the Z-axis supporting plate structure.

The article has analyzed the changes of temperature of different materials of the spindle, and considered 170SD30 Ceramic Motorized Spindle and the same model Metal Motorized Spindle as the research objects, analyzed the inside heat source and heat transfer mechanism of the high-speed motorized spindle; used finite element software to set up the model of the motorized spindle, and did simulation and analysis. Verified by simulation, heat transfer rate of ceramic materials is slower than the metallic materials, in actual operation of the process, due to different materials have different heat transfer rate, so the temperature distribution of the different materials of motorized spindle are different. This conclusion provides the basis to solve motorized spindle temperature field distribution.

Steering knuckle connects steering system, suspension system and braking system to the chassis. The steering knuckle contributes a significant weight to the total weight of a vehicle. Increasing the efficiency of an automobile without compromising the performances is the major challenge faced by the manufacturers. This paper presents an effective topology optimization of steering knuckle used in a vehicle with the primary objective of minimizing weight. The study on optimization of knuckle is divided into two phases, the first phase involves making of a computer-aided design model of the original steering knuckle and carry out finite element analysis on the knuckle by estimating the loads, which are acting on the component. In the second phase, design optimization of the model of steering knuckle is carried out, and excess material is removed at the region where induced stress is negligible as obtained in finite element analysis assuming standard boundary and loading conditions. The paper describes a research work carried out to optimize structural topology giving the essential details. The methodology may be applied to optimize structural components used in applications where the ratio of desired properties to the cost, generally in terms of weight, is to be optimized. In the case of automobiles, strength to weight ratio has to be maximized. New researchers working in the area will have an understanding of the procedures, and further, the techniques may be applied to design in general.

A new permanent magnet bias axial magnetic bearing (PMAB) is introduced, then the structure and operation principle are analyzed. The equivalent magnetic circuit is established to deduce the mathematic expression. The parameter design and calculation of the magnetic bearing are presented including available area of magnetic pole, ampere - turns of control coils etc. The parameters of the proposed prototype are also given. The 3-D magnetic field simulation is performed by using the Finite Element software. The theory analysis and the simulation show that the maximum suspension magnetic force satisfies the design requirement. The magnetic suspension forces have better linearity and symmetry around the balanced position. Therefore, the proposed PMAB is suitable for the high speed or low loss occasions.

The objective of this paper is to design and analyze a horizontal tank on saddle supports. The horizontal vessel is to store various chemicals used in today’s industry. The over all dimensions of the horizontal vessel are determined from the capacity of the stored chemicals. These dimensions are first determined. The design function is performed using the ASME Code Sec VIII Div 1. The horizontal tank design is broken up into (a) shell design, (b) two elliptical heads and (c) two saddle supports. The designed dimensions are used to recalculate the stresses for the horizontal vessel. The dimensioned horizontal vessel with saddle supports and the saddle support structure is modeled using STAAD III finite element software. The stresses from the finite element software are compared with the stresses obtained from calculated stresses by ASME Code Sec VIII Div 1 and L. P. Zick’s analysis printed in 1951. The difference in the stress value is explained. This paper’s main objective is to compare the code design to the finite element analysis. The design is found to be safe for the specific configuration considered.

In order to meet the requirements of high-speed train's safe operation, the horizontal displacement of high-speed railway bridge pier top must be strictly controlled. This paper relies on one road construction engineering beneath an existing high-speed railway bridge. We use 2D finite element software to analyze the magnitude and direction of pier top horizontal displacement caused by road load. We take it into account that the effect of the soil nature on pier top horizontal displacement. The analysis showed that the nature of soil around piles of high-speed railway bridge is closely related to the magnitude and direction of the pier top horizontal displacement. Authors believe that the horizontal displacement of pier top consists of two parts. One is pier top pure horizontal displacement dragged by horizontal displacement of the top of piles, the other is pier top rotation horizontal displacement driven by the rotation of pile cap. The analysis result can be used for the design of road with embankment structure beneath high-speed railway bridge.
