Conventional planar fins are designed like miniature wings whereas grid fins have smaller lattice aerostructures arranged within a box-like structure. Most grid fins have square grid aerostructures such as those used in the Falcon 9 rocket manufactured by SpaceX. This paper discusses the introduction of 3 innovative designs namely trapezoidal, triangular and hexagonal grids in two configurations - un-tapered and tapered. The taper angles will be 6, 6.5, 7 and 7.5. These new designs will be modelled and analysed using suitable software. The designed grid fins will be simulated in multiple aerodynamic conditions at various angles of attack. The exit velocity of air at the outlet of the grid fin will be measured and analysed in this paper. Once the simulation is complete, the two best designs will be 3D printed with appropriate materials at appropriate scales for wind tunnel testing. The results will be compared and validated with existing data in order to find the overall effectiveness of the designs.","PeriodicalId":14391,"journal":{"name":"International Journal of Vehicle Structures and Systems","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80187612","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The practice to examine the flaws which leads to serious effects in rail track is rail inspection. Among the world countries, Indian railways are the fourth-longest, but when it comes to reliability and safety it lags to provide world standard. As a result, if the track is damaged, it leads to severe loss of valuable human lives and property. This derailment in tracks is caused due to cracks in the rails. Therefore, an early crack detection and protection system is required to save the lives. This paper proposes a customized design of an inductive transducer and crack detection system on railroad tracks to avoid the train accidents. Existing method uses the manpower to identify the cracks and this involves human errors. So, the drawbacks in the existing method can be reduced by the automatic system. Customized inductive sensor is designed and developed using ANSYS. A scaled down model of a cart is fabricated and the inductive sensor is assembled at beneath surface of the cart. The track is acting as a part of the magnetic core for the inductive sensor and voltage is induced in the sensor. The sensor voltage is calibrated to distinguish the magnitude of voltage from the normal to crack.","PeriodicalId":14391,"journal":{"name":"International Journal of Vehicle Structures and Systems","volume":"111 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76307969","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A hybrid MMC was produced for the chamber liner of cutting-edge diesel motors. Dry sliding wear testing equipment, employing a pin-on-disc wear tester, is used to examine the wear properties of casted hybrid metal matrix composites. The examination shows that the wear opposition of Al-6061 is expanded while adding the chicken bone ash and graphite as support content. Within the current work, effort has been made to survey the tribological properties of aluminium as-projected combination test for Al amalgam and unadulterated aluminium. The operational boundaries were a typical load and sliding velocity of the pin concerning rotating disk at temperature. The medium utilized was dry and wet greasing. The amount of mileage has been decreased altogether in aluminium alloy similar to unadulterated aluminium. Dry condition testing showed huge loads of noise and a similarly more measure of mileage for both aluminium and aluminium alloy. The coefficient of contact for aluminium alloy in wet conditions was roughly steady up to the applied load and then diminished with additional utilization of load while the coefficient of friction for unadulterated aluminium was rising persistently with the load. Evaluation of the corrosion conduct of the aluminium MMC is achieved by the usage of the salt spray method or immersion test and the results are considered.","PeriodicalId":14391,"journal":{"name":"International Journal of Vehicle Structures and Systems","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78403429","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The MMC comprises aluminum alloy AA6061 as the matrix element and 5%, 10% and 15% by weight of silicon carbide particulate (SiCp) as the reinforcement material, before and after heat treatment. This investigation compares the mechanical properties and metallurgical characteristics of the MMC with the base material AA6061. In the present investigation, stir casting method is used for preparing samples of MMC. The produced composites were subjected to heat treatment to enhance their hardness. The influence of the weight composition of the reinforcement particles on the mechanical properties of the MMC is analyzed quantitatively. The mechanical properties such as tensile strength, impact strength and hardness were measured for quantitative analysis, while scanning electron microscope is used for qualitative analysis. The temperature of the furnace and the hardening time during the heat treatment process control the hardness exhibited by the composite materials. The percentage composition of reinforcements in the composite materials influences their mechanical properties. Based on the results, optimal material has been suggested for a wide range of applications. The proposed investigation indicates that if the heat treatment increases, then the microhardness of the MMC increases by 13.86%, 18.45% and 30.19%, respectively for 5, 10, and 15% by weight SiCp. It is also observed that the maximum tensile strength of MMC is 329 MPa at 10 % by weight of SiCp. Compared to the base material, it is a 12.5% increase in its tensile strength. Increase in the percentage composition of SiCp to 15wt. % reduced the impact strength by 13%. The scanning microscopy reveals that MMC having 10% by weight of SiCp has a medium-size grain structure.","PeriodicalId":14391,"journal":{"name":"International Journal of Vehicle Structures and Systems","volume":"32 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79608702","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
