description |
Tyre pressure loss is a common phenomenon whereby, air from the tyre chamber would be naturally released to the atmosphere causing its pressure to drop from time to time. It has been reported that, almost 80% vehicles on the road are running with underinflated tyres which is due to lack of user awareness of the importance running their cars with properly inflated tyres. Running with below recommended/pre-set pressure often leads to catastrophic tyre failure which leads in major road accidents. One of the main reasons for the negligence in maintaining tyre pressure is due to the hassle of having to check and inflate the tyre manually. Therefore, many ideas and systems have been initiated since the past to ensure correct tyre pressure is maintained at all time. Unfortunately, there is no one complete system found in the market to date for the matter. Therefore, a novel Tyre Pressure Replenishing System (Pre-Rep) has been researched, which has also been filed for patent. This research successfully established a system which could ensure the tyre pressure is sustained at a safe pre-set limit at all time without human intervention. The system design has been verified to contain the maximum operational pressure by using the finite element method to analyse the strength of the pressure capsule design. The structural
analysis of the system has been verified by Finite Element Analysis incorporating maximum pressure obtained from mathematical modelling, and maximum tyre temperature obtained from thermal investigation which experimentally conducted over a travelled distance with two sets of speed limit. Finite element analysis being the critical engineering analytical tool reveals that, the structural design advocated AISI 304 Stainless Steel as the work material which resulted factor of safety to be 1.2 which is considered safe for pressure vessel fabrication. The proposed technology comprises a combination of high pressure capsule called pressure capsule to automatically replenish air into the tyre when deflation occurs so that the pressure in the tyre is always maintained to its set value without one having to worry about checking or even monitoring the pressure. This system works as an embedded unit where it is installed onto a standard automobile wheel. The research methodology with critical considerations has successfully enabled the development of successful Pre-Rep after incorporating the mathematical modelling output into the finite element analysis which was later tested and experimentally validated using Proton Perdana V6. The compensation performance and the results show that Pre-Rep is capable to compensate the tyre pressure loss with pressure check sensitivity of 7 kPa pressure cut-off accuracy 14 kPa. This very much complies with the tyre pressure monitoring system sensitivity range used worldwide proving agreement of the designed system to automatically inflate the tyres. Pre-Rep besides overcoming all the hustles to maintain safe tyre pressure, it is also able to provide comfort and economical drive besides lifesaving by reducing or eliminating major road accidents due to tyre explosion. |
