Curve fitting using python

Model: An airfoil shape curve was created from xyz co-ordinates of Boeing 103 Airfoil found in the NACA database. The unit system used is MKS system. The curve was converted into sketch entity using convert entity feature. The sketch was closed and extruded (0.5 m) to form a solid model of the airfoil. Simulation: A time-based…

For this challenge we first make a cylinder of diameter 20 mm and length of 50 mm. Next, we create a new flow simulation project using the wizard. We change the analysis type to external and make it time-dependent. Next we add water as the liquid. Next we initiate the velocity in X direction as 1.54 m/s for the baseline…

First make a pipe with following dimension: Internal Diameter: 18 mm Outer Diameter: 20 mm Length: 1000 mm Lines are drawn across the length of the pipe at 850 mm, 900 mm and 950 mm from the inlet side of the pipe. These lines will be used as line probes in results. Create a lid using the Flow Simulation module in Solidworks…

A valve train is used in engines to control the opening and closing of the inlet valve of air-fuel mixture as well as the exhaust valve. A cam is designed as per the geometry and the valve timings required and is coupled directly or indirectly with the crankshaft to change the timings as per the engine speed. The cam is…

The following inputs were used for designing the Planetary Gear Ring Gear Module = 2.5 (metric system) Number of teeth = 46 Sun Gear Number of teeth = 14 Input Speed of the Gear = 200 rpm. Number of planet gears = 4     Calculating the number of teeth in planet gear: (Module is same for all gears) Pitch…

Objective: Create a 3D model of Internal Geneva Mechanism using the 2D CAD Drawings. Perform motion analysis on the same for following scenarios: 10 RPM without precise contact 10 RPM with precise contact 20 RPM without precise contact 20 RPM with precise contact NOTE: The RPM is the speed of the driver wheel in the mechanism.…

MBD simulation on Piston assembly is to be done. For this we need to make parts such as follows: Piston Head     Wrist pin       Connecting rod       End cap         Crank       All the above parts are assembled as required.     Motion…

Let  `f(x,y)=5-(x-2)^2-2(y-1)^2` `g(x,y)=x+4y-3=0`        (1)   We solve, `∇f=λ ∇g` To simplify, we introduce ‘Lagrangian function’, L and calculate its critical points `L=f-λg`     `∴L=5-(x-2)^2-2(y-1)^2+λ(x+4y-3)`  …
