Tools for Mechanical Design Engineers

Machine design has been one of the most challenging jobs for engineers since time immemorial. Unlike today, people used 2D drawings to design the parts. With the advancement in technology, we are now able to bring our design living in our imagination to a visual form and test for the feasibility of design in terms of strength, durability, and manufacturability. This post explains the two most popular tools used by mechanical design engineers to bring their imagination into a working reality.

Design Workstation : Select the best

The world is a much better place if you have one of the best workstation desk available. The fact that all the design software are always hungry for the resources of your system, forces the companies to develop best in class performance chips for the users. But these technologies come at a cost which is not affordable for the common user like freelancers, small-scale industries, institutions, students etc. For us, we have “Personal Computers”. But we need to select wisely in order to get the best out of the resources available to us.

In this blog, we will help in selecting the best rig available for your work and budget, and best of all, we update it continuously so that you are always having the latest technology with you.

Automobile Systems Design

If you ever thought of making your own car, you might have come across a point where you thought of designing your car. Basically one can be divided into two different segments


  1. Exterior body designing for looks

2.  Automotive components and system design


This blog is about the later one: Automotive components and system design, which includes design of 5 basic systems of an automobile, viz.

  1. Chassis/Body
  2. Transmission
  3. Suspension
  4. Brakes
  5. Steering

Design of Rocket Engine Exhaust

The physics used in rocket design is not very different to what we read in our schools but with a slight change that some laws of physics are changed a such high velocities. Earlier we posted about the blunt shape of rockets and missiles. This post is about the design of Rocket Engine Outlet or Throat. In this post you will also learn about the simulation of flow of exhaust from the rocket engine which will help you better understand the design of rocket engine throat.

Why Missiles and Rockets are Blunt from Top?

Everyone knows that air planes, missiles and rockets are designed to minimise the air friction by creating an “Aerodynamic shape”. We all were taught in school that they have a streamlined design that allows air to pass easily. But what makes the design more streamlined? A Pointed top like in most fighter jets or a Blunt top like in missiles or Rockets.

Design of Hub and Knuckle

If you have ever participated in any student racing championship, such as mini BAJA, You must be aware of the tough competition given by the teams in all the aspects. Whether it is a static event or a dynamic event, we get to see a new height of engineering used by the students. Out of all the events, the most challenging event that affects both your static as well as dynamic performance is “Design Inspection”. If your design is good, you get to score in static as well as dynamic events.

Though there is a lot to do in the design of a vehicle, in this blog I will tell about the designing of one of the most important and expensive manufactured part in a buggy for BAJA.
