Finite Element Analysis of Universal Joint and Propeller Shaft AssemblyOptimum Design And Analysis Of A Composite Drive Shaft For An Automobile By Using Genetic Algorithm And Ansys Aug 2012 1874-1880 1) It has been observed from above table 22 which is obtained by FEM analysis of shaft of concrete mixer machine that maximum shear stress and equivalent stress both are greater than allowable shear and equivalent stresses of existing shaft material 2) Thus, failure occurs in the shaft … SHARE: An inadequate alignment of the propeller shaft often results in the late delivery of newbuilds, and costly off-hire due to damage or failure of the stern tube bearing for ships in operation. Ship propeller shaft. -6 9. Changes in propeller design 2. Changes in hull design 3. A propeller shaft, transmission drive shaft, driving shaft, drive shaft or cardan shaft is an automobile ... the dynamic response and thermal analysis of heavy vehicle transmission gearbox system using FEA method. If you installed a propeller that was too large in diameter or that had too much pitch, then the propeller curve (Propeller Power Curve A) would be shorter and steeper and would intersect the engine power curve at some point less than maximum 2,700 RPM, per-haps at 2,100 RPM. shaft, Composite Structures 70 (2005) Page: 33–47. As the industrial arena grows more sophisticated, it seems as though operations are confronting fewer and fewer broken machine shafts. TYPES OF DRIVE SHAFT There are various type of transmission shaft among them following are important 1. Satisfactory operation of heavy duty transmission system may depend to a large extent upon the successful handling of the vibration problem. 6. In this paper we analyze a composite Propeller Drive Shaft for power transmission, it demonstrates the favorable factors and identifies the suitable composite Propeller . Thermal Medium Medium Conductivity Damping Medium High Capacity IV. Characteristics of composite material:- Whereas the shafts, which propel (push the object ahead) are 1) They have high specific modulus and strength referred to as the propeller shafts. EP Editorial Staff | July 16, 2012. 6 0 0 Analysis of Propeller Shaft for Composite Materials Vinodh Kumar S, Sampath V and Baskar P School of Mechanical and Building Sciences, VIT University, Vellore, INDIA Available online at: www.isca.in , www.isca.me Received 18 th November 2013, revised 27 th March 2014, accepted 2nd October 2014 There are commonly three types of propeller: 2-blade, 3-blade and 4-blade. M.R. This article discusses failures in shafts such as connecting rods, which translate rotary motion to linear motion, and in piston rods, which translate the action of fluid power to linear motion. In this project the Structural Analysis of Contra Rotating Propeller is carried out by Finite Element Analysis (FEA). Loading... Home Other. Design, Analysis and Comparison of Propeller Drive Shaft of an Automobile . DNV GL experts perform root cause analysis for ship and MOU shaft alignment and aid owners/yards in obtaining safe, compliant shaft alignment. Machine shaft. Now a day’s two piece steel shaft are mostly used as a drive shaft. If the propeller shafts are inclined in any significant way, this gives rise to a cyclic variation in the advance angle of the flow entering the propeller. Static and Thermal Analysis on Mechanical Shaft Using Titanium Alloy Rishabh1, Prateek Srivastava2, Atul Raj Shukla3, Bhupender Singh4 1,2,3 Graduate Student, Mechanical Engineering, Faculty of Engineering and Technology Manav Rachna International Institute of … Shorter shafts (except container vessels) Hence, increased bending moments and stiffness and sensitivity on bearing influence coefficients 1. Propeller shaft failure is one of the major problems facing for MSRTC workshop supervisors and Engineers. 4. the propeller shaft of a vehicle was chosen and analyzed by replacing it with different materials. The engine crankshaft has an equivalent (continuous shaft) diameter of 330mm. DESIGN AND MODELLING OF THE SHAFTInitial Diameter of Shaft: A. The diagnostics using this method are called thermal diagnostics. JS Carlton, in Marine Propellers and Propulsion (Second Edition), 2007. Firstly, various kinds of losses, which include iron, air friction and bearing losses are identified for this cooling system. Increased propeller weight and efficiency 3. Spindle. Now assume the shaft power is fixed, then the efficiency is determined by the thrust generated by the propeller. Vibration Analysis of Propeller Shaft Using FEM. Shaft power is produced by the motor, which will be discussed in the later section. (Research Article, Report) by "Shock and Vibration"; Physics Dynamics Identification and classification Dynamics (Mechanics) Marine propulsion systems Equipment and supplies Shafting Mechanical properties Shafts (Machinery) Ship propulsion Vibration (Physics) Dimensional analysis leads to a number of coefficients which are useful for presenting performance data for propellers. (propeller/shaft/engine weights) are supported by journal bearings (stern tube bearings, ... and the static equilibrium of the shaft is calcu-lated using matrix analysis. Free Online Library: Propeller excitation of longitudinal vibration characteristics of marine propulsion shafting system. 1Akshay G. Khande, 2Shreyash A. Sable, 3Vaibhav R. Bidwai, 4Chandrasekhar B. Aru, 5Brahmanand S.Jadhav 12345 Mechanical Engineering Department, Babasahebh Naik College of Engineering, Pusad, Maharashtra, India Abstract — Propeller shaft is the major component of 3. $\begingroup$ Why would you think one should do a thermal analysis of a propeller? 11. It describes the process of examining a failed shaft to guide the direction of failure investigation and corrective action. The analy-sis for this case study has been comprised of chemical composition analysis, micro-structural characterization, fractography, hardness measurements, and finite element simulation. Helicopter tail rotor shaft. So in our analysis we will consider the Carbon fibres because its advantages include high specific strength and modulus, low coefficient of thermal expansion, and high fatigue strength which is ideal fibre for torque transmitting shaft. 2. Operation of the propeller at a different pitch setting, and the propeller pitch change will change the torsional stiffness of the transmission shaft unit. 7. The report projects the Axle & Propeller Shaft to emerge as one of most profitable verticals, amassing substantial remuneration by the end of the forecast duration, recording a commendable growth rate over the estimated span. ISSN: 2454-6410 ©EverScience Publications 1 Abstract— A drive shaft, also known as a propeller shaft or cardan shaft, it is a mechanical part that transmits the torque generated by a vehicle’s engine into usable motive force to propel the vehicle. As a result, the length of the propeller shaft is reduced, along with the stern tube bearing span used to support it.
