Week 3 - Solving second order ODEs

Objective: The objective of this challenge is to simulate the action of a bullet hitting a bucket and penetrating it. This is an explicit dynamic simulation however, the materials for the bucket are supposed to be non-linear. For this simulation, the materials chosen for the bucket were Alluminium alloy (NL), Copper alloy…

A planer is a type of metalworking machine tool that uses linear relative motion between the workpiece and a single point cutting tool to cut the work piece. A planer is similar to a shaper, but larger, and with workpiece moving, whereas in a shaper the cutting tool moves. The most common applications of planers and shapers…

Tesnion Test: Tensile tests are used to determine how materials will behave under tension load. In a simple tensile test, a sample is typically pulled to its breaking point to determine the ultimate tensile strength of the material. The amount of force (F) applied to the sample and the elongation (∆L) of…

Objective: A universal joint (universal coupling, U-joint, Cardan joint, Spicer or Hardy Spicer joint, or Hooke's joint) is a joint or coupling connecting rigid rods whose axes are inclined to each other, and is commonly used in shafts that transmit rotary motion. The main objective here is to perform a Transient structural…

Objective: The objective of this challenge is to understand how to perform a transient analysis and to study the movement of a cam follower with rotation of a barrel cam.  This challenge consists of three cases in which the contact friction is varied from frictionless to friction coefficient value 0.1 and finaliction…

Objective: The objective of this problem is to study plastic deformation on a metal sheet when it is hit by a spherical object. Both the objects are considered to of structural steel however, the plate material is considered as non-linear. The sphere presses 4 mm into the sheet metal and then retracts, this deformation…

Objective: To simulate the rolling operation on a workpiece made of copper. The problem statement gives us the model of roller and workpiece setup, the challenge is to perform structyural analysis for the same. The problem needs u to find the stresses in the entire setup, the strain in the workiece and the deformation…

Wire Bending: Plastic deformation of metal wire where the wire is fed forward, bent in one or more steps and subsequently cut loose. The work piece consists of a metal wire is fed through the split die adapted with bending pins suited for the bending shapes. The rotary bending tool  bends the wire around the die resulting…

Objective: Simulation of three different types of welding using three different weld materials. To study effects of different types of weldments on the component and compare strengths of different types of welds.Type of weldments used determines the strength of the joint and would affect the amount of load that can be…

Objective: The objective of the following simulation is to perform sheet metal bending analysis in Ansys workbench. Variation in analysis is introduced such as changes in materials, changes in friction coefficient as well as different alloys of same material so as to understand effects of various properties on the results…

Objective: Perform a static structural analysis on the Railwheel and Track setup. Rail wheel and track assembly is the most coomon component of a rail carriage. the load of the entire carriaage is borne by the shaft and wheel assembly and transferred on the the track through the wheel. It can be observed in the attached…

Objective: To understand the signficance and use of grid dependancy in structural simulation and understand how to use parametric analysis.   Write a few words on what a grid dependency test is and its use.   Grid dependency test is to investigate how the solution depends on the grid size by running the simulation…

There are two objectives to the given problem, Simulate stresses on a set of spur gears with three different material selection. Compare the results to find out best suited material for allocation. Objective 1: Simulation of stresses on a set of spur gears. Step 1: Geometry Creation The geometry was imported from the model…

Design a plate with a hole model similar to what we worked in the class, but with increased thickness.Determine the maximum deformation and stress developed in the model. Objective: Numerical analysis of stress in a plate with holes in two given cases. Comparison of the results in two given cases. Selection of design based…

Implement control logic of a “washing machine” using Stateflow as per given sequence:  If the power supply is available, the system gets activated  If the Water supply is not available, stop the process & indicate through LED Soaking time should be 200s followed by Washing time of 100s. Then rinsing…

What are Genetic Algorithms? Genetic algorithms are a part of a bigger group of algorithms called evolutionary algorithms and are a learning method inspired by evolutionary biology.    The process of natural selection starts with the selection of the fittest individuals from a population. They produce offspring which inherit…

A simple pendulum consists of a ball (point-mass) m hanging from a (massless) string of length L and fixed at a pivot point P. When displaced to an initial angle and released, the pendulum will swing back and forth with the periodic motion. By applying Newton's second law for rotational systems, the…

What is an air standard cycle? The air standard cycle is a thermodynamic power cycle that converts heat energy into mechanical power by considering air as a working fluid with constant specific heat. In this cycle, the air is the only working fluid that goes through changes in its thermodynamic properties to convert heat…
