Speed and high availability have always been among the strengths of ACE Stoßdämpfer GmbH. Depending on the request, the company based in Langenfeld, Germany, which specializes in automation, motion and vibration control as well as in safety products, supplies customers in the German-speaking region of Europe with a wide range of machine components within 24 hours. These also include industrial gas springs of push and pull types, which are mainly mounted on hoods, flaps, hatches and machine covers and serve to relieve muscle strength by closing and holding and by reliably handling masses without much effort for the users.

In the past, inquiries about the availability of a suitable ACE gas spring required direct contact with the ACE gas spring team and the completion of a drafting form sent by fax or e-mail. Thanks to the new online calculation program for gas springs, the design via graphical user interface now takes place faster and at any time.

Unique in the industry, because it is completely intuitive, visually structured and optionally supports 2D or 3D visualization, the most common applications of gas springs can now be calculated in a few structured steps. At experienced users can thus reach the machine element tailored to their application in less than a minute. The exact matching ACE gas spring and the required mounting accessories are specified precisely. In addition, a montage sketch can be generated with the help of the online tool.

In the interest of their customers, ACE Stoßdämpfer GmbH uses this service to shorten the entire process from design, through ordering, to delivery. While the order is triggered by an automatic request to both show delivery time and price in the current version of the software, the plan for the future is to let customers use the online calculation 24/7 and check-out directly via ACE's e-shop. After the order, now and in the future, each individual gas spring is filled with nitrogen in the Langenfeld warehouse of ACE and shipped by parcel service. For customers who prefer the previous service, both personal advice and assistance in calculating and ordering the right ACE gas springs for every application are of course still available by phone, e-mail and direct consultation with the ACE sales team in the customer's region.

"The unrivaled user experience with comparable tools for our industrial and safety shock absorbers has been incorporated into the development of this unique, user-friendly solution that allows our customers to determine which ACE gas spring is ideally suited for almost any of their diverse applications," says André Weßling, responsible for both worldwide marketing and the online tools project group at ACE Stoßdämpfer GmbH. He emphasizes that the focus of the effort has been on making the operation of the new online calculation program for the ACE gas springs as comfortable and intuitive as possible. At prospective customers can now put the program to the test to find out how well ACE Stoßdämpfer GmbH has accomplished this task.

It is important that you enter the requested data as accurately as possible. The calculation tool can then calculate a gas spring as accurately as possible and determine the points where to attach the gas spring. When you click on a question mark you will see a brief explanation of what exactly you must enter. First of all you need to click the image that most closely resembles your application. The first image applies, for example, to a toy box. The second image on a market stall. The third image applies to an angled cover. The fourth image applies, for example, to a horse trailer. For the calculation, pictures 1 and 4 are actually the same. Only the visualisation and simulation then correspond better with your actual application.

Select here the number of gas springs that you want to apply. Usually two gas springs are used: one on both sides of the cover. It is also possible to use one gas spring, but then there is a chance that the cover will skew or not close completely close to where the gas spring is located. This will happen less likely in case you place the gas spring in the middle of the cover. Even then it is important that the cover is stiff enough so that the cover will not bend on both sides.

In addition, the stainless steel 316 gas springs are higher quality. These gas springs have a grease chamber and a built-in clean cap. A grease chamber ensures that the gas spring seal is always properly lubricated, so that it does not matter how the gas springs are positioned. These gas springs can therefore also be mounted with the piston rod upwards or be positioned completely horizontally, without the seal drying out and the gas springs starting to leak. A clean cap ensures that the piston rod is scraped clean, so that no dirt gets into the interior of the gas springs. As a result, the stainless steel 316 gas springs can also be used in the more dirty environments.

The moment (force times arm measured from the hinge) of the cover in Newton meter (Nm) and the moment (also measured from the hinge measured in Nm) of the gas springs work in the opposite direction, leaving you with a moment in one of the two directions. What you have left is the force (in N) that you still have to use by hand to hold the cover at that certain angle. It is therefore different at every angle in which the cover is held.

The hand force can also be seen in the 2D simulation at the blue arrow. If the moment of the cover (the green line) and the moment of the gas springs (the red line) intersect in the graph, no manual force is required (the blue line). There are two red lines. This has to do with the fact that the insertion of a gas spring costs more force than the extension of the gas spring, due to the friction that must then be overcome. A red area therefore appears in the graph. If the green line falls in the red area, the cover will therefore remain in that position.

Because the insertion of the gas springs is heavier than the extension of the gas springs, two blue lines and a blue area will also be created. This is because the manual force will also have to be greater when the gas springs are pushed in (closing the cover) comparing to the sliding out of the gas springs (when the cover is opened).

The cover is 750 mm = 0.75 m long. So in Nm (Newton meter) the hand force at the end of the cover is 27.47N x 0.75m = 20.60Nm. That is also the difference between the red square (moment of the gas springs in Nm) and the green square (moment of the cover in Nm). Red is namely at approx. 80 Nm and green at approx. 60 Nm.

The simulation specifies the maximum force that will be applied to the hinges of the cover when the gas springs are mounted. By placing gas springs, more is required of the hinges. The force that appears here is an indication of how strong the hinges should be. You may need to install stronger hinges. You can read more information about the force that will be applied to the hinges of the cover and how this can possibly be absorbed here.

If you are going to calculate a gas spring, and the proposed gas spring is quite expensive, you can also select a cheaper gas spring that has more or less the same length as the proposed gas spring. So possibly a gas spring with the same diameter but then a slightly longer or shorter stroke, or a gas spring with a different diameter. The larger the diameter, the more force the gas spring can have. The 4-12 can be up to 200N, the 6-15 can up to 450N, the 8-19 can up to 800N, the 10-23 can up to 1250N and the 14-28 can up to 2500N.

In general it holds that the longer the gas springs (so with a larger stroke) the less force on the hinges of the cover. Often a slightly longer or slightly shorter gas spring will make little difference to the result. You can always check that in the simulation after you have selected the other gas spring. Once you have selected another gas spring, the calculation tool will immediately calculate with this gas spring.

This is the stroke of the gas spring that will not be used. The minimum unused stroke is 10 mm. There is always room for a little play if the gas springs are not mounted to the mm. Sometimes it may be convenient to increase this distance. This is the case, for example, if the place to mount the gas spring is better. However, the smaller you choose this value, the more you make useful use of the stroke of the gas spring. We therefore advise you to stay close to 10 mm.

Select here the mounting parts to be fitted to the tube side of the gas spring. That is therefore the thicker part of the gas spring. This is usually the mounting part that you mount to the cover. The tube must in fact be directed upwards at rest for proper lubrication of the gas spring. Often a bearing shoe is required as an attachment. With a bearing shoe you can mount the gas spring against the bottom of the cover. If the cover has edges at the bottom, you can also choose a side bracket.
