To design a high-quality vehicle shock absorber, the internal structure of piston assembly absorber is analyzed in this study. Using fluid–solid coupling method, high-precision flow grid model and solid finite element stacked valve are built analyzed. A bidirectional method proposed, which can be adopted to simulate analyze dynamic nonlinear response characteristics for slice Workbench software...

In this paper, the authors focus on presenting methodology for tuning optimization algorithm parameters, with a special evolutionary applications. The problem considered concerns phenomenon of nonlinear buckling automotive shock absorber, which itself is solved using commercial application finite element method (FEM) simulation. These analyses are usually time-consuming; therefore, decided to u...

Elastomeric proteins are molecular springs that confer excellent mechanical properties to many biological tissues and biomaterials. Depending on the role performed by the tissue or biomaterial, elastomeric proteins can behave as molecular springs or shock absorbers. Here we combine single-molecule atomic force microscopy and protein engineering techniques to create elastomeric proteins that can...

OBJECTIVES Despite many hypotheses, the pathophysiology of syringomyelia is still not well understood. In this report, the authors propose a hypothesis based on analysis of cerebrospinal fluid dynamics in the spine. METHODS An electric circuit model of the CSF dynamics of the spine was constructed based on a technique of computational fluid mechanics. With this model, the authors calculated h...

With the increasing number of bicycle riders, there is an increased risk of accidents between bicycles and automobiles. Some accidents are caused by speeding bicycles and the lack of communication between the cyclist and car drivers. To close the communication gap, we propose a method to detect speeding behaviors using a conventional smartphone. Using the smartphone, the cyclist will be able to...

Vehicle dynamic analysis has been a hot research topic due to its important role in ride comfort, vehicle safety and overall vehicle performance.. For proper designing of suspension system, nonlinearities in suspension parameters must be considered. In this paper, nonlinearities of spring and damper are considered while preparing quarter car model. For this a simplified model and experimental s...

BACKGROUND Toxic shock syndrome is a potentially fatal toxin-mediated disease. The role of toxins in this clinical entity made us hypothesize that extracorporeal blood purification with CytoSorb® could play a beneficial role in the clinical management of toxic shock syndrome. This case report describes the successful treatment of toxic shock syndrome using a combination of renal replacement the...

Automobile wheels are an essential and important part of any automobile from their invention to today they have taken on various designs changes, structures, styles. Main function is carry the overall weight vehicle, resist forces & stresses created during driving transmit torque achieve required speed while driving. Wheels must well strength stiffness having durable design withstand runnin...

Background The human heel fat pad (HFP) is an effective shock absorber [1]. A remodelling of body fat begins from the fifth decade of the human life. Diet may negatively influence this distribution and consequently lead to corpulence in elderly persons. Alcantara and colleges reported that fat content in the HFP increases with obesity [2]. Hence, the purpose of this investigation was to determi...

Centrifugal pendulum vibration absorbers (CPVA) are used in the automobile industry to reduce vibrations of transmission system. These passive devices made several masses oscillating along a given trajectory relative rotor. In this paper, dynamic stability new class CPVA is investigated. The particularity that now admit significant rotation motion rotor, addition traditional translation motion....
