Study on Body Rigidity, Strength and Fatigue Performance for Carbon Fiber Reinforced Plastics Vehicles

Weight reduction of car is now main issue in order to increase vehicle fuel efficiency. Among various lightweight materials, CFRP (Carbon Fiber Reinforced Plastics) is at the head because of superior stiffness and strength to weight ratio. A durability performance development process of CFRP vehicle was studied, and applied to fuel cell concept car Intrado (code name HED9) in order to check compatibility of the process. CFRP material was identified as a solution for satisfying weight lightening and performance of vehicle concurrently by comparing with general steel structure vehicle.

SIMULATION OF COMBINED FORMING AND INJECTION MOLDING PROCESSES

Injection and compression molding of fiber reinforced thermoplastic materials are proven and efficient processes to produce lightweight parts for automotive applications. By adding continuous fiber reinforced composites or sheet metal, the possible range of applications can be greatly increased while retaining the advantages of the molding processes, cost efficiency and design flexibility. So called hybrids parts are used for more and more applications, especially in the automotive industry. The reinforcements are formed by the closing motion of the mold and the flow of the molding material. A novel approach is suggested using Abaqus/Explicit coupled eulerian lagrangian simulation to model combined forming and molding processes.

Prediction of compressive characteristic of hat section high-strength steel frame taking the Bauschinger effect into account

In recent years, the usage of high-strength steel is increasing in order to improve the rate of body weight reduction and the safety performance of a vehicle from crash. The Bauschinger effect is generally strong in high-strength steel sheets. Material properties used in crash analysis is conventionally treated as isotropic hardening material. However, the analysis results such as average loading and buckling wavelength from analysis deviates with those from tests, which is observed in some axial collapse problems of hat section frame that is composed of high-strength steel sheet. When axial collapse occurs in the hat cross section frame, buckling occurs along with a frame ridge rolling.

Application of Predictive Engineering Tool to Determine Optimize Rubber Door Harness Grommet Design

A cable grommet is a tube ring through which an electric cable passes. They are usually made of rubber or metal. The cable grommet is used to protect, improve friction or seal cables passing through it, from a possible mechanical or chemical attack and for aesthetic look. It becomes very important to determine the optimum length of the grommet used for particular application. Bigger length will have results into folding of grommet and lesser length will yield into stretching of rubber grommet. Finite element simulation technique presented in this paper can be used to determine the optimum geometry of the grommet. Component used for this study is an automotive door harness rubber grommet.

Strength Assessment of Injection Molded ShortFiber-Reinforced Plastic Components

Components made of short-fiber-reinforced plastics (SFRP) are stressed highly both mechanically and thermally. Therefore an intelligent component design is required in order to fully exploit the potential of these materials. Hence, the design of such components must be based on a reliable strength assessment. For this purpose models for the description of the anisotropic and elasto-plastic failure behavior of SFRP are required. In contrast to the widespread use of SFRP, methods for a reliable strength assessment based on FE analyses for components made of these materials have not been sufficiently developed yet. This paper presents an approach for the strength assessment of SFRP components based on FE analyses. In the scope of this appropriate failure limits and failure criteria for these materials are presented.
