How to calculate gas strut position
Gas struts, also known as gas springs, are crucial components in various applications, including automotive, marine, and industrial equipment. They provide support, adjustability, and smooth motion for various mechanisms. One of the fundamental aspects of successfully using gas struts is determining the optimal position for their installation. This article will outline the steps necessary to calculate the proper gas strut position for your application.
Step 1: Identify the Pivot Point
The first step in determining the gas strut position is identifying the pivot point or mounting point of the mechanism that will be supported by the strut. In most cases, this point will coincide with a hinge or other movable joint.
Step 2: Determine Strut Force Requirements
To accurately calculate the position of a gas strut, you should determine its force requirements first. This can be done using the following formula:
Force_required = Weight x Distance_from_pivot / 2
– Force_required is the force needed to support the mechanism
– Weight is the overall weight of the moving part
– Distance_from_pivot is the distance from the pivot point to the center of mass of the moving part
Step 3: Choose a Suitable Gas Strut
Based on your force requirement calculated earlier, select a gas strut with suitable force characteristics. Ensure that it can support not only static loads but also prevent any unwanted motion or vibrations during use.
Step 4: Calculate Mounting Position
To find out where to mount your gas struts along with their brackets, follow these steps:
a) Decide on an attachment angle (A): This angle is typically between 30° and 60°. Smaller angles provide more support and larger angles allow greater range of motion.
b) Calculate extended length (L): Using trigonometry and extended_length = A x tan(angle)
c) Determine stroke length (S): By calculating the difference between the fully extended and compressed lengths of the strut.
d) Calculate the mounting distance (D): Using a ratio of stroke length (S) to extended length (L), determine the mounting distance from the pivot point.
Step 5: Verify Mounting Position
Before finalizing the mounting position, ensure that it will not interfere with other components or movement of your mechanism. Additionally, check that the gas strut can support and move your mechanism without excessive force or binding.
Calculating gas strut position is crucial for ensuring proper function and longevity of equipment. Following these steps will help you obtain the right positioning for your specific application, as well as make any necessary adjustments along the way. Remember, always consult manufacturer guidelines for additional information and specifications on your chosen gas struts, and seek professional assistance if unsure about any aspect of the process.
