MEboost has a four bar linkage synthesis tool for the three types of linkage synthesis. This article will explain terms, conventions and constraints. This is the first of four articles on four bar linkage synthesis. The remaining articles will show specific examples of each synthesis type. Part 2: Four Bar Path Synthesis Part 3: Four …
This is part of a series for synthesizing four bar linkages using MEboost. In this article we will use four bar function synthesis to design a linkage. It’s recommended to view part 1 for terms and conventions used in MEboost. Part 1: Four Bar Linkage Synthesis Part 2: Four Bar Path Synthesis Part 4: Four …

This is part of a series for synthesizing four bar linkages using MEboost. In this article we will use four bar motion synthesis to design linkages. It’s recommended to view part 1 for terms and conventions used in MEboost. Part 1: Four Bar Linkage Synthesis Part 2: Four Bar Path Synthesis Part 3: Four Bar …
Linkage synthesis is designing a linkage to meet a desired output. Since most linkages are capable of complex motion, this has been a daunting task except for specific linkages with predictable motion. In this article we will look at various types of linkage synthesis. Before getting to far, we need to define the term “precision …
The slider crank is a very common linkage that is found in a variety of machines. The most recognizable version of the slider crank is found in an engine in the form of a crank shaft, connecting rod, piston, and cylinder. This mechanism also comes in different forms called slider crank inversions. The slider crank …
Hydraulic cylinders are the muscle of a hydraulic system. In this article we’ll present the equations for hydraulic cylinder calculations and discuss efficiency. Cylinder Equations – SI These are the formulas for SI units. All formulas are for theoretical values. Cylinder Equations – US These are the formulas for US units. All formulas are for …
Hydraulic pumps are the heart of a hydraulic system. In this article we’ll present the equations for hydraulic pump calculations and explore efficiencies. We’ll start with the equations in SI and US units. Pump Equations – SI Pump Equations – US Hydraulic Pump Efficiencies There are three types of efficiency associated with a hydraulic pump. …
In this article we’ll dive into hydraulic motor calculations and the important topic of efficiency. Many hydraulic calculators ignore efficiency altogether and merely calculate theoretical values with 100% efficiency. Manufacturers typically don’t get too deep into efficiency either. First we’ll present the equations for various parameters of a hydraulic motor in both SI and US …
The planetary gear train is an important, but complex mechanism. When it comes to analyzing rotation directions and gear speeds, intuition is not enough. We’ll look at the superposition method to determine speeds and rotation directions. For a planetary (a.k.a. epicyclic) gear train there are three possible inputs/outputs: two gears and the planetary gear carrier. …
