Side protective beams:
As noted earlier, to enhance occupant safety and reduce the injuries and also absorb more energy during side impacts, nowadays, inside the car door, hollow tubes and also profiles with open sections and various forms of cross-section are embedded which are useful and very efficient in order to meet these requirements.
In this part, we are looking for the best profiles for the thin-walled side protective beams of cars’ doors so that fulfill some criteria mentioned as follow:
- The rate of energy absorption: To determine the amount of this energy, the force- deformation diagram is applied. The area under the graph represents the amount of energy absorbed by the side protective beam.
- The amount of deformation: to obtain the rate of deformation, the force- displacement diagram can be used.
According to the paper [10], one of the first models used in various vehicles as side protective beam, called a C-shaped profiles which can be seen in Figure 4a.
Another model has been also presented in paper [10], called 2S profile which is of open profiles and is shown in Figure 4b.
Next profile is called 3S which is our proposed design in order to compare the effect of increasing the number of bumps and dents in the profile section and is presented in Figure 5a.
The other profile which I propose is of open section profile. This profile which is called Half-C is proposed to investigate the effect of the perpendicular sides or lack of them in the rate of absorbed energy and displacement. This profile is shown in Figure 5b.
After introducing several profiles with open cross-sections, several closed section profiles will be introduced. The first and simplest closed cross-section profile to offer is a profile with circ...

... beams of cars’ doors. The main purpose in this paper is finding the characteristics of the most efficient cross-section for these tubes. For this purpose, at the beginning, the process of simulation is validated according to the reference [1]. Then, several diverse types of profiles are modeled and side impact for each one of them is simulated. Each one of these profiles is presented for studying a specific geometrical characteristic of the cross-section. Then, force- displacement graphs for these profiles are compared. These comparisons are studied in two different sections, the rate of displacement and the rate of absorbed energy. It can be concluded that the most efficient profile should be closed profile, have larger area along the impact direction, and have more surfaces along the impact direction. All of these characteristics are gathered in Bumper profiles.

Today, engineers rely on damping systems to counteract nature's forces. There are many types of damping systems that engineers can now use for structures, automobiles, and even tennis rackets! This site focuses on damping systems in structures, mainly architectural variations of the tuned mass damper.

For decades, the Bavarian Motor Works automotive company, more commonly known as BMW, has been an icon in European luxury automobiles. It has done an extraordinary job in setting the standard for other manufacturers from Europe, Japan, and the United States auto markets. But what keeps the customer pleased with the BMW brand is not only its vehicles superb handling and performance, but its ability to inject a certain character into the automobiles themselves. This is achieved by the use of certain design elements that can be traced through history to the earliest of the BMW models. These elements include: the aerodynamic body style of the cars and sport utility vehicles, the Hofmeister Kink which is a characteristic that involves design of rear seat windows, the quadruple headlight configuration, and the famous kidney grille that is tucked into the front bumper giving the car an all-around exclusive exterior style.
I have chosen to look at the effect of the weight applied, as it is a

This essay will discuss about the research method on the designing and analysing the nose cone design of 2014 formula 1 race car. This research is aimed to analyse the 2014 formula 1 nose cone design and optimised it to get a better design of the nose cone but still have aerodynamic flow and also still meet the regulation requirement of 2014 formula 1 championship. There are four main objectives to help fulfil the aim of the project they are: design the nose cone of selected teams by using engineering design software, simulate the nose cone design by using flow simulation and finite element analysis engineering software, optimised the design to get the better shape of the nose cone, and critical analyse the 2014 formula 1 nose cone design and the optimised nose cone design.

where Ff is the force produced by the feedback spring and kf is the stiffness of the feedback spring.
In Chapter 14 (Kinetics of a Particle: Work and Energy) and Chapter 18 (Planar Kinetics of a Rigid Body: Work and Energy), both apply a same concept. It is concept of work and energy to solve the problem. Chapter 14 use the concepts of work and energy to analyze motion of a particle, while Chapter 18 apply work and energy methods to solve planar motion problems. In both chapter, problems that involve force, velocity, and displacement can be solve by using the resulting equation.

Therefore, the elasticities for each independent variable will need to be computed as follow because this will provide the breakdown of how each variable will represent within
Bull bars- A bull bar is a device attached to the front of the vehicle to minimise the damage caused to passenger in the case of a crash. Bull bars come in all different shapes and sizes depending on needs. If your car was to collide with a kangaroo, the car passengers would feel the thump because the mass of the kangaroo is big enough to cause damage. The car would also slow down naturally without the driver putting their foot on the brake, because the force has either been thrown forward or over the car (law 1 and 3). The bull bar is designed to stop the force from coming in contact with the cars bonnet.
