Currently, wind energy in Mexico is growing and the same is happening worldwide, so projects with national technologies for the manufacture of wind turbine components must be developed. In this work, a proposal is made for the design of the hub of the rotor for a 50-kW turbine, the objective is to make a new proposal to improve the previous design of project P07 of the Centro Mexicano de Innovación en Energía Eólica (CEMIEEólico), which has a welded mechanical hub for a prototype turbine 30 kW. In addition, a simulation is performed through analysis of the finite element method (FEA) by applying certain load elements with the simplified load method of the international standard IEC 61400-2. In these simulations, the load cases of the norm that directly influence the cube are analyzed, then simulated in the ANSYS software to validate the proposed design, mainly analyzing the stresses and deformations. The results obtained will serve as a reference to manufacture the cube and evaluate the feasibility of carrying out a commercial stage with a view to making national components for wind farms.

Delamination is detrimental to the composite materials, and it may occur in the manufacturing process of the unidirectional laminate of the spar cap in wind turbine blades. This paper studies the effect of different delamination defects on the strength of the unidirectional laminate. The finite element model of laminate with different delamination areas and delamination heights is established using solid elements. The eigenvalues of laminates have different parameters calculated based on the finite element method. The final coupon test is used to verify the conclusions of simulation results. The finite element method presented in this study shows excellent capabilities to predict the buckling behavior of the laminate. The buckling eigenvalue of tested laminate is negatively correlated with the delamination area and positively correlated with the delamination height under the edgewise load. The S11, which is too high at the boundary of the delamination region, plays a significant role in buckling failure. It has a particular reference value for testing the laminate of blade both in theory and practice.

Currently CNG has been widely used as an automotive fuel, and the security problems about CNG storage well are prominent which poses a serious threat to life and property.This indicates that the safety of the underground gas storage well stored CNG is of great importance. The purpose of this paper is to analyze the section of gas storage well that is the joint of casing and coupling based on the finite element method,as this section is the most dangerous.Using ANSYS software,the stress field of this section will be acquired.An example of a finite element model will be used to demonstrate the main section related to gas storage well failure is the root of the first engaged tooth of a joint between coupling and casing.

This paper is devoted to the derivation of material indices using the finite element method. Material indices take into account material properties such a Young’s modulus and density are a powerful tool for material selection for various applications since they allow a quick comparison of suitability of different materials. Until now material indices were developed analytically for rather simple textbook-like examples. However, by implementing the finite element method and data fitting tools material indices can be developed for more complicated problems where the analytical solution cannot be obtained. The current paper describes derivation of material indices using ANSYS software. It is used as a simulator of a physical phenomenon. The simulation generates output data which is used to derive the material index.
