Rocket Science is Easy! The Calculations

EmailFacebookGoogle+LinkedInTwitterShare

As mentioned in “Rocket Science is Easy“(the previous blog in this series), a set of fundamental calculations need to be completed  before the rocket design can be finalized.  The calculations are the basis for the rocket’s stability and performance. The stability calculations will be addressed first, as they have a direct effect on the performance of the rocket. Stability Calculations Two variables directly affect the stability of a rocket, The Center of Pressure(Cp) and the Center of Gravity(Cg).  The relationship […]

Need to Know a Force but Only Have a Value for Displacement? No Problem.

As engineers we face common force control problems throughout our design process. Designing a deck? We can calculate the dead load based on number of people, furniture, materials etc.. Designing a door handle? We can estimate the amount of force an adult would apply. Designing a fan blade?  We know the torque applied by the motor.  The above are examples of force applied problems.  We give the software the load (force, torque, pressure) and we receive insight into the stress, […]

Tangible Solutions Helps Businesses Excel with 3D Printing

EmailFacebookGoogle+LinkedInTwitterShare

Many manufacturers struggle to understand how 3D printing can integrate with their business. By now the marketplace is aware of 3D printing however, with hundreds of different 3D printer offerings, applications and materials there can be significant confusion for the appropriate decision. Managers often experience difficulty with justifying the upfront costs, learning curve requirements and of course, the return on investment analysis necessary of 3D printing technologies. Tangible Solutions assists companies to address this challenge.  Tangible Solutions educated and trains […]

Flow Simulation Header Transient Analysis

In the previous blog “Flow Simulation and the 75 Dollar Question”  the differences between a stock, aftermarket short tube, and aftermarket long tube header were analyzed.  Flow Simulation was utilized to compare the headers and decide whether or not the long tube header was worth the extra 75 dollars.  The criteria used to evaluate the headers was total pressure drop.  A constant flow into all four runs and a pressure outlet was used to evaluate the over all pressure difference. […]

Quick Tip: Linear Pattern-Up to Reference

EmailFacebookGoogle+LinkedInTwitterShare

In SOLIDWORKS 2015, Up to reference was added as an option in Linear Patterns.  Typically you set the distance between the instances and the number of instances.  Now you can specify the distance up to some piece of geometry allowing the software to figure out either the distance or instance count. You still choose an edge for the pattern direction.  You now choose Up to reference and something to reference to.  You are building a much more intelligent model while […]

Nominal Wall Thickness Inside Plastics Simulation

EmailFacebookGoogle+LinkedInTwitterShare

Wall Thickness – a major concern when designing a plastic part. During the injection of the mold the melted plastic flow front will always move in the direction of least resistance. You can think of this similar to water flowing through a pipe.  The larger the pipe the easier the volume of water will flow.  If the wall is too thick in comparison to other sections of the part the plastic flow will “Race Track” or move ahead of the […]

What is the Vary Sketch Option in a Pattern?

EmailFacebookGoogle+LinkedInTwitterShare

I have an option that you might have overlooked or just didn’t know what it does.  It’s the Vary Sketch option. The definition from the Help File says, “Select the Vary Sketch option to let the pattern instances change dimensions as they repeat.”  Let’s take a look at what you have to do and how it might help you. So what I’m going to do is create a triangular part first. Now we need to have a feature added to […]
