What is T.J Prabhu's Design Methodology?
T.J Prabhu's design methodology is based on a systematic and logical approach that follows these steps:
Identify the design problem and its specifications.
Analyze the forces and stresses acting on the machine element.
Select a suitable material for the machine element.
Choose a standard or preferred size for the machine element.
Check the strength and stiffness of the machine element.
Modify the design if necessary to meet the safety factor or other criteria.
Verify the design by testing or simulation.
Document the design process and results.
T.J Prabhu's design methodology emphasizes the importance of considering various factors that affect the performance and durability of machine elements, such as wear, fatigue, corrosion, creep, impact, vibration, noise, lubrication, friction, temperature, etc. The book also provides guidelines for selecting appropriate factors of safety and service factors for different applications and conditions.
How does T.J Prabhu use CAD, Optimization and FEM?
CAD (Computer-Aided Design) is the use of computer software to create and modify geometric models of machine elements. CAD helps to visualize the shape and dimensions of machine elements and to perform various analyses such as stress analysis, kinematic analysis, dynamic analysis, etc. CAD also facilitates the generation of drawings and documentation for manufacturing and assembly.
Optimization is the process of finding the best possible solution for a given design problem by minimizing or maximizing a certain objective function subject to some constraints. Optimization helps to improve the efficiency and effectiveness of machine elements by reducing their weight,
cost, or material usage, or maximizing their strength, stiffness, or performance. Optimization can be performed using various methods such as mathematical programming, genetic algorithms, simulated annealing, etc.
FEM (Finite Element Method) is a numerical technique for solving complex problems involving the behavior of structures and materials under various loads and conditions. FEM divides the domain of the problem into smaller and simpler elements and applies the governing equations to each element. FEM can handle problems involving nonlinearities, large deformations, contact, cracks, etc. FEM can also be coupled with CAD and optimization to perform integrated design and analysis.
T.J Prabhu's book introduces the concepts and applications of CAD, optimization and FEM in machine design and provides examples and case studies to illustrate their use. The book also discusses the advantages and limitations of these tools and suggests best practices for their implementation.
