The basic parameters of a hydraulic cylinder are:  <\/p><ul><li>maximum executable force<\/li><li>maximum extendable path length<\/li><li>maximum extension speed<\/li><\/ul><p>These parameters determine the basic suitability of this component. A hydraulic cylinder can offer many advantages, but if these parameters are not met, the device is useless for the intended purpose. <\/p><h3>The installation location in the calculation of a hydraulic cylinder<\/h3><p>The second stage of conditions relates to the installation location. Here, it must be determined within which framework the hydraulic cylinder is allowed to move: <\/p><ul><li>Weight of the linear motor<\/li><li>Size of the linear motor<\/li><\/ul><p>The weight of the linear motor is particularly important for vehicles. The lighter the hydraulic cylinder, the less energy is required for its transport. Furthermore, a lower weight reduces the static load on the vehicle frame. This, in turn, can be made lighter or from less expensive materials, which again saves weight and energy.   <\/p><p>It is therefore sensible to define a linear motor as precisely as possible. A precisely calculated linear motor also allows conclusions to be drawn about the required <a href=\"https:\/\/www.bf-hydraulik.com\/en\/hydraulic-pump\/\" target=\"_self\" title=\"Hydraulic pump provides pressure and volume flowThe hydraulic pump is the core component of a hydraulic system.

The vehicle as a whole becomes cheaper and lighter.  <\/p><h3>Calculate hydraulic cylinders: Formula and procedure<\/h3><p>The following variables are required for the exact calculation of a linear motor:<\/p><p>D = Piston diameter &Oslash; in mm<br>d = Piston rod diameter &Oslash; in mm<br>A = Piston area in cm2 (Calculated via D&sup2;\/4 &times; &pi;)<br>p = Pressure in bar<br>F = Force dN (? kg)<br>h = Stroke in mm (=distance)<\/p><p>The most fundamental of all parameters for hydraulic cylinders is its producible compressive force. Therefore, the formula for calculating the hydraulic cylinder is designed for force. It is:  <\/p><p>Force = Pressure &times; Piston Area \/ F = p &times; A = dN<\/p><p>In <a href=\"https:\/\/www.bf-hydraulik.com\/en\/hydraulic-system\/\" target=\"_self\" title=\"Hydraulic system: design &amp; applications explained simplyA hydraulic system is used to apply large forces in a targeted manner over a defined distance with minimal effort. The underlying hydraulic principle&hellip;\" class=\"encyclopedia\">hydraulic system<\/a>s, however, the efficiency in hydromechanical systems must be taken into account. This is approximately assumed to be 0.85 &ndash; 0.95. <\/p><h3>Three formulas for calculating the hydraulic cylinder<\/h3><p>Compressive force: Fd = (p &times; D2 &times; 0.785 &times; &eta;hm) \/ 100 = dN<br>Pressure: p = (Fd &times; 100) \/ (0.785 &times; D2) = bar<br>Diameter: [(Fd &times; 100) \/ (0.785 &times; p)]^1\/2<\/p><p>It therefore requires several passes until you have worked your way towards the desired performance parameters of the ideal linear motor. You then select the most suitable hydraulic cylinder from a standard parts catalog. Important: when selecting, you must always round up, i.e., choose the next larger cylinder, otherwise the <a href=\"https:\/\/www.bf-hydraulik.com\/en\/hydraulic-system\/\" target=\"_self\" title=\"Hydraulic system: design &amp; applications explained simplyA hydraulic system is used to apply large forces in a targeted manner over a defined distance with minimal effort.
