The objective of this paper is to design, analyze, and test the space frame for electric vehicle with comparison to the engine type. Therefore, in order to design the electric vehicle formula, the same requirements with some changes are considered. The space frame is designed to suit with the electric vehicle and then finite element analysis is used to determine the torsional stiffness of the frame which is verified by the torsional test. Initially, the required torsional stiffness for the electric car is 1350 Nm/deg and the mass is set to be not more than 40 kg. The numerical results and the experimental results for torsional stiffness are 960 Nm/deg and 1218 Nm/deg, respectively. Therefore, the torsional stiffness is about 25% under-predicted; anyway it can be used to predict the torsional stiffness of the frame. Due to some changes must be performed, therefore the modified frame is re-analyzed with the torsional stiffness of 1389 Nm/deg which is less than the revised required car’s torsional stiffness of 1404 Nm/deg. Anyway, the torsional stiffness of frame with battery’s case can meet the requirement. The mass of the modified frame is 50 kg which is larger than required mass due to selected sizes of steel tubes. In conclusion, the space frame can be designed and the mass can be improved further by reducing the sizes.

This paper will detail the design challenges and construction of the extension of the New Mexico Rail Runner commuter rail corridor from Bernalillo, NM to Santa Fe, NM. Numerous innovative solutions were implemented in the design and construction of the project to meet the aggressive schedule dictated by the client. The project was awarded to the design-build contractor in August 2007 and the line was opened to traffic in December 2008. This project was an important component of the New Mexico statewide transportation improvement project. Project final design and construction plans for the 18 mile extension were completed in five months. Construction started prior to completion of the final construction documents. The design was planned to provide a steady flow of Approved for Construction (AFC) documents to facilitate construction. Project highlights included eighteen miles of welded rail on concrete ties, six railroad bridges, one highway bridge overpass, two rail passing sidings, six concrete box rail crossings and 18 miles of new 136lb welded rail on concrete ties. The project is designed to meet the operating requirements of Class IV track and an operating speed of 79 mph. The major civil quantities included two million cubic yards of earthwork, 59,000 square feet of MSE retaining walls, 263,000 tons of ballast and subballast, 98,000 track feet of rail, and 50,000 concrete ties. The project team (NMDOT and Design-Build Consortium) collaborated by meeting weekly and reviewing plans and solutions, prior to acceptance for construction. Key to this effort was the use of the 3D design model created for the entire project leading to refining of the project quantities, reducing cost and allowing the NMDOT to remain within the budget established for this project.

This paper presents the final design of glass-reinforced polyester (GRP) blade for 10 kW wind turbine developed at the Technical University of Moldova by finite element (FE) analysis techniques. This design was reached through an iterative analysis process following a previous design. The objective of this research is to maximize structural robustness of composite blade while reducing its mass and cost. Design optimization of the composite wind turbine blade was performed by checking the static and dynamic behavior. The design variables considered are related to the composite material parameters: fiber direction, layups direction and blade shell thickness based on number of composite layers. The constraints are tip deformations, allowable stresses and resonant vibration of the blade. According to FE analysis results the optimized blade will be stiff enough in storm conditions, will operate out of dangerous resonance frequencies and will weigh approximatively 20% less.

Since torsional loading and the accompanying deformation of the frame and suspension parts can affect the handling and performance of the car, torsional stiffness is generally thought to be a primary determinant of frame performance for a FSAE car. According to the FSAE Rules, different tube cross-sections are available for some members of a space frame. By finite element simulation, this research compared different tube shapes and thicknesses. Compared with 1.6 mm thickness round tube, square tube with the same wall thickness can improve the torsional stiffness by 23% in test Mode I, and 65% in test Mode II. The 1.2mm thickness square tube also can improve the torsional stiffness by 6% and 39% in test Mode I and Mode II. From these comparisons, it can be found the usage of square tube can improve the frame torsional stiffness efficiently.

The design of semi-monocoque frame by using the composite-steel joint is considered in this paper. The frame is designed with weight less than 30kg and torsional stiffness more than 1200 Nm/deg. In order to design the semi-monocoque frame, the analysis of the composite-steel joint has to be clearly investigated. Therefore, the stress analysis of composite-steel joint is performed and then the frame is designed. The double lab joint with two holes is tested and verified by the experiments. The carbon-fiber fabric laminated with the KEVLAR fabric composite laminate is used for composite part. From experiments, the joint’s strength can be increased by using the eccentric holes. Therefore, in order to meet the requirement of the SAE rules; load capacity more than 30 kN, the eccentric hole double lap joint is numerically designed and applied to semi-monocoque frame. The joint has strength of 32 kN and can be used in frame design. The semi-monocoque frame is designed and analyzed by finite element analysis. The maximum stress at maximum load is 208 MPa which is less than the yield strength of the materials so it can withstand the loads, the mass is 29.6kg, and the torsional stiffness of the frame is 1408 Nm/degree. Therefore, the semi-monocoque frame can be successfully designed.

Abstract Shell Eco-Marathon (SEM) is an international competition among university students that involves designing, building, and driving energy-efficient cars. The car frame is the most crucial aspect influencing the strength of the car. This research aims to obtain maximum torsional strength with variations in the material and thickness of the frame. Calculation and testing are done using the simulation method to obtain a strong car frame. This simulation method is calculated by a series of finite element analyses. Then, data from the simulation method are obtained in the form of deformation and safety factors. By comparing the moment received with its deformation, torsional stiffness is then obtained. Furthermore, the torsional stiffness is divided by the weight to produce a value ratio. It is known that the factor which has the most significant influence on the difference in torsional stiffness of each variation is the shear modulus of the material used. In contrast, the weight of the chassis is influenced by the density of the material and the thickness of the chassis. Additionally, the safety factor of each variation is strongly influenced by the strength of the chassis structure itself. The results of this study will demonstrate the car frame design with the best performance.
