Aesthetic, structural and financial constraints combine to demand continual improvements in design efficiency and optimisation.
Development process of new bumper beam for passenger car: A review Bumper beam absorbs the accidental kinetic energy by deflection in low-speed impact and by deformation in high-speed impact.
The safety regulations "low- and high-speed, and pedestrian impacts" along with new environmental restrictions The safety regulations "low- and high-speed, and pedestrian impacts" along with new environmental restrictions "end-of-life vehicles" increased the complexity level of bumper system design.
The new bumper design must be flexible enough to reduce the passenger and occupant injury and stay intact in low-speed impact besides being stiff enough to dissipate the kinetic energy in high-speed impact. The reinforcement beam plays a vital role in safety and it must be validated through finite-element analysis FEA and experimental tests before mass production.
The careful design and analysis of bumper beam effective parameters can optimize the strength, reduce the weight, and increase the possibility of utilizing biodegradable and recyclable materials to reduce the environmental pollution. Developing the correct design and analysis procedures prevents design re-modification.
On the other hand, analysis of the most effective parameters conducive to high bumper beam strength increases the efficiency of product development.
Cross section, longitudinal curvature, fixing method, rib thickness, and strength are some of the significant design parameters in bumper beam production. This study critically reviews the related literature on bumper design to come up with the optimal bumper beam design process.
It particularly focuses on the effective parameters in the design of bumper beam and their most suitable values or ranges of values. The results can help designers and researchers in performing functional analysis of the bumper beam determinant variables.The response of composite laminate structure to three-point bending load was investigated by subjecting two types of stacking sequences of composite laminate structure by using electronic universal tester (Type: WDW) machine.
Design by analysis finite element damage mechanics numerical methods are applied to investigate post first ply failure and stress redistribution. The study shows that different loading combinations can give rise to different damage mechanisms and ultimately failure loads.
Design and Analysis of a Laminated Composite Tube Words | 9 Pages COMPOSITES COURSEWORK DESIGN AND ANALYSIS OF A LAMINATED COMPOSITE TUBE ABSTRACT This report details the process for the design of a composite laminate tube, the software package 'MathCAD' was used to determine a lamina design .
5. STATIC ANALYSIS OF EXISTING AND NEW HELMET This composite material helmet was formed by means of the Solid works software and all the new composite material are added in it.
Further we did static analysis for different parameters like stress, strain and deformation.
The Figure-2 represents the composite material helmet model. Figure Composite fan blades are a key feature of this engine and an enabling technology with respect to fuel efficiency, cost efficiency, and innovation. Snecma was responsible for the development of the overall fan blade design and from a manufacturing standpoint is responsible for finishing, final control, and ultimate integration into the fan module.
