And Performance

Based on finite element analysis technology, a static simulation model of the swing-rod constraint reciprocating piston-type oil-free air compressor was established for stress analysis of the compressor. Simulation results show that the stress in the main parts of the new compressor is within the permitted range, so structure design and parameter setting of the compressor are reasonable. Moreover, the force condition of seal rings is improved by adding swinging-rod constraint mechanism, which will prolong the service life of seal rings. With this study, these simulation results will guide further modification and performance improvement of the compressor.

The Finite Element Model

Taking a mobile air compressor frame as object of the research, for the load generated by the weight of engine, fuel tank and the cooler which are installed on the frame, adding mass and concentrated force are two methods which is used to simulate modeling.Under the working conditions of being hoisted ,combined with the stress-strain electrical experiment , finite element analysis was carried out on the model which is established, then the simulation results of two models were analyzed. It turned out that the established model is credible. For the issue of the load on the frame, it proves that adding mass to simulate the load is a practical and efficient way for modeling.

Abstract In this paper, we study the energy absorption of metamaterials composed of unit cells whose special geometry makes the cross-sectional area and the volume of the bodies generated from them constant (for the same enclosing box dimensions). After a parametric description of such special geometries, we analyzed by finite element analysis the deformation of the metamaterials we have designed during compression. We 3D printed the designed metamaterials from plastic to subject them to real compression. The results of the finite element analysis were compared with the real compaction results. Then, for each test specimen, we plotted its compaction curve. By fitting a polynomial to the compaction curves and integrating it (area under the curve), the energy absorption of the samples can be obtained. As a result of these investigations, we drew a conclusion about the relationship between energy absorption and cell number.

The Impact

Energy efficiency and leakage magnetic field (LMF) are two important issues in inductive chargers. In this work, the maximum achievable coil efficiency and the corresponding LMF strength are formulated as functions of system parameters, and figure of merits (FOM) are proposed for assessing the efficiency and LMF performance of the coil assemblies. The target application is electric vehicle inductive chargers where the LMF is suppressed via passive shielding. The impact of the coil assembly’s geometric parameters on both FOMs is examined through a combination of finite element analysis (FEA) simulation and magnetic circuit analysis, and measures to improve the FOMs are studied Optimization of an exemplary coil assembly within given dimensional limits is conducted and the performance improvement is verified by FEA simulation results. <br>

Cylindrical Roller

A dynamic finite element analysis model for cylindrical roller bearing is developed, and the complex stress distribution and dynamic contacting nature of the bearing are investigated carefully based on ANSYS/LS-DYNA. Numerical simulation results show that the stress would be bigger when the element contacting with the inner or outer ring than at other times, and the biggest stress would appear near the area that roller contacting with the inner ring. Phenomenon of stress concentration on the roller is found to be very obvious during the operating process of the bearing system. The stress distributions of different elements are uneven on the same side surface of roller in its axis direction. Numerical simulation results can give useful references for the design and analysis of rolling bearing.

Frame adalah salah satu komponen yang sangat penting dalam sebuah kendaraan, yang berfungsi sebagai penopang penumpang, mesin, suspensi, sistem kelistrikan dan lain-lain. Melihat fungsi dari frame sangat penting, maka dalam merancang sebuah frame harus diperhitungkan dengan baik. Banyak sekali jenis pengujian yang sering dipakai dalam perancangan sebuah struktur frame, salah satunya adalah digunakannya metode komputasi dengan menggunakan metode Finite Element Analysis (FEA). Tujuan dari penelitian ini adalah untuk mengetahui distribusi tegangan, regangan, displacement, dan safety factor dari hasil pembebanan statis pada frame gokar. Struktur frame didesain dan dianalisis menggunakan software Solidworks 2016. Material yang digunakan frame adalah baja AISI 1045 hollow tube 273,2 mm, dengan menggunakan pembebanan pengendara sebesar 50 kg dan 70 kg. Hasil dari perhitungan manual didapatkan tegangan maksimum sebesar 4,735  107 N/m2, sedangkan dari simulasi didapatkan sebesar 4,516  107 N/m2. Regangan maksimum didapatkan dari perhitungan manual sebesar 2,310  10-4. Displacement maksimum didapatkan dari perhitungan manual sebesar 1,864  108 mm, sedangkan dari simulasi didapatkan sebesar 1,624  108 mm.

The frame is one of the most important components in a vehicle, which functions as a support for passengers, engines, suspensions, electrical systems and others. Seeing the function of the frame is very important, so designing a frame must be taken into account well. There are many types of tests that are often used in the design of a frame structure, one of which is the use of computational methods using the Finite Element Analysis (FEA) method. The purpose of this study was to determine the distribution of stress, strain, displacement, and safety factor from the results of static loading on the kart frame. The frame structure was designed and analyzed using Solidworks 2016 software. The material used in the frame is steel AISI 1045 hollow tube 27  3,2 mm, using a rider load of 50 kg and 70 kg. The result of manual calculation shows that the maximum stress is 4,735  107 N/m2, while the simulation results are 4,516  107 N/m2. The maximum strain is obtained from manual calculation of 2,310  10-4. The maximum displacement is obtained from manual calculations of 1,864  108 mm, while the simulation results are 1,624  108 mm. The minimum safety factor obtained from manual calculation is 11,193, and the simulation calculation is 11,736.
