ABSTRACT A motoben'szy, rcycle cap is the best defensive set out rigging toward the anticipation of head wounds brought on by various cranial effect. A limited component show in view of reasonable geometric elements of a bike head protector is set up, and unequivocal limited component, ansys, is utilized to mimic element reactions at various effect speeds. Top increasing speed and Head Injury Criterion values got from the head frame are utilized to survey the defensive execution of the protective cap. In this present work engine cycle protective cap is outlined and displayed in 3D demonstrating programming Catia. The effect investigation is performed on the cap when crashing to an objective at various paces of 50 Km/hr, 60 Km/hr and 70 km/hr that faces the head protector on the front, right and back headings utilizing ANSYS programming. The materials utilized for the cap is ABS, PVC and PP(polypropylene). Key words: Motorcycle Helmet, Geometric Elements, Head Injury Criterion.

Additionally, genuine engine cycle mishaps have expanded over the most recent two decades. To outline a useful head protector, it is essential to examine the structure of caps. The fundamental head protector segments are the froth direct and the shell. Essentially, the capacity of the froth is to ingest the majority of the effect vitality, while the capacity of the shell is to oppose infiltration of any outside protest from touching the head and bringing about editor@iaeme.com

2 B.Siva Kumar, B.Sai Krishna, M.Raveendra prasad, J.Yaswanth and Dr.G.Diwakar direct skull harm, and to disseminate the effect stack on a more extensive froth range in this way expanding the froth straight vitality retention limit. The drive resistance test is the primary criteria for shell thickness assurance and, truth be told, bringing about a protective cap with a thicker shell and thusly a weight of around 6 to 8 times when contrasted with the froth liner. On the off chance that a thicker shell is picked, the quality will increment, shockingly, and in addition cost and weight or an option material ought to be considered. For investigation its better outcome head protector outline and material property has been tried and contrasted and standard. 2. THE EVOLUTION OF THE HELMET Another man likewise thought of the thought for a bike protective cap. Teacher C.F. Lombard of the University of Southern California created and protected a head protector that had an inside layer expected to retain and scatter the stun of effect. Be that as it may, early cap models were incapable. It would take many years of research in materials and configuration to make caps work.

As here the head protector is planned in Catia V5 and examination is considered in Ansys programming According to the postulation the Analysis is done in various stages, as the materials considered here are PVS, PPC AND ABS and examination is done at various velocities i.e 50kmph, 60kmph and at 70 kmph. As though we check the outcomes if so the protective cap investigation is done at 50kmph, the outcomes got here the anxiety (2.4168e7) is less for PPC material, however while strain ( ) is less for ABS material and going to the disfigurement ( ) is likewise low for ABS material as it were. Going to the following examination if so the head protector investigation is done at 60kmph, the outcomes got here the anxiety (2.7303e7) is less for PPC material, yet while strain ( ) is less for ABS material and going to the distortion ( ) is likewise low for ABS material as it were. Going to the following examination if so the head protector investigation is done at 70kmph, the outcomes acquired here the anxiety (3.2935e7) is less for PPC material, yet while strain ( ) is less for ABS material and going to the distortion ( ) is additionally low for ABS material as it were. So at long last we can reason that if the cap is made with ABS plastic the head protector is sheltered and gives more existence with solidness editor@iaeme.com
