Your score on GrabCAD is not terribly important, but it is nice to have a better score, and not be "ranked" dead last on a site with four million users. What can you do to increase your score?

Mechanics Basics Part 1

This tutorial is a look at some of the basic terms and what they represent in a basic mechanics context. Most of the basic mechanics, the starting point for good mechanical design grew out of the work of Sir Isaac Newton. Newton’s work introduced the fundamental terms and principles of mechanical design by application of the physical laws of the universe. From regularly looking at some of the questions posted here on GrabCad, even taking into consideration that for many here, English is not their main language exactly what the person asking a particular question actually wants to know, is sometimes quite hard to deduce. Some things should be universal in most languages especially when working with the ISO standard S. I. Units. As tutorials of this sort benefit from having a downloadable pdf version accompanying this online version, on Grabcad, and as the concept of providing a downloadable pdf version has not entered into GrabCad's concept of a useful feature for tutorials, I will also provide a pdf version for those that may want one. My tutorial Gear Basics Part 1 was entirely in pdf format with just a link to where you could get it from. The Grabcad management were not happy with this so they removed it. If anyone wants the pdf version just mesage me through Grabcad mail, leaving an email address to sent it to.

Designing a Hirth Spline

Solidworks + Excel instruction on how to design a Hirth Spline. Background on Hirth Splines: https://en.wikipedia.org/wiki/Hirth_joint The basic idea of a Hirth spline / Hirth Joint is that the whole geometry is defined from a combination of a single reference point and a grinding/cutting geometry. Two Hirth splines with the same basic tooth geometry will match to form a secure joint that can transfer torque and allows for accurate alignment of parts. Hirth splines and joints are often used in turbomachinery to accurately align various shaft parts and transfer torque.

Fundamentals of the theory of industrial dust protection with bag filters

ALance

The oldest cleaning method for bag filters (still used in mobile filters these days) consists of motorised or manual jolting equipment. With automatic regeneration, a motor is started, either at certain intervals or when reaching a maximum filter resistance. This oscillates the filter element. During the resulting movement, the deposited dust cake detaches from the filter surface and drops down into a dust collector, which is usually cleaned via dust dischargers. Mechanical cleaning is performed after interruption of the filtration. The filter bags are stressed mechanically through shaking during the cleaning operation and therefore have relatively short service lives. The periodic reversal of the flow direction (backwashing filter) is a much gentler cleaning method. Here, the filter system features several separate chambers which are cleaned individually. A combination of both cleaning methods was also often realised. For the last decades, however, the jet pulse method has become the standard cleaning method. The filter media are regenerated through cyclic, intense blasts of compressed air. This briefly causes overpressure in the filter bag during cleaning. The filter bags are briefly inflated, the flow direction is reversed and the filter cake detached (fig. 1). A supporting cage gives the bag the required stability during the filtration phase. Among other things, the cleaning cycles depend on the filter load (volume flow per filter surface and unit of time), the gas density, the raw gas charge and the particle attributes. The regeneration can be controlled in time intervals or via defined differential filter pressures.
