Calculate Gas Strut Position

How to Calculate Gas Strut Position

Calculating the optimal gas strut position is essential for ensuring the functionality and longevity of your application. Follow these precise steps for accurate set-up.

Tools Required

To start, you need access to an online calculator like the one provided by Gasspringsshop, which simplifies the calculation process. This tool is geared specifically for calculating gas strut mounting positions based on the specifics of your project.

Initial Measurement

Begin by measuring the length of the lid on which the gas strut will be mounted. The accuracy of this measurement is crucial as it will determine the subsequent steps.

Mounting Point Calculation

The moving mounting point of the gas strut should be your initial focus. From the hinge, mount the gas strut at approximately 30% of the total length of the lid. Use the simple formula: Mounting Point = 0.3 * Lid Length.

Strut Length Determination

Next, determine the optimal length of your gas strut. Generally, the length of the strut should be about 55% of the height of the door being kept open. Use the calculation: Strut Length = 0.55 * Door Height.

Optimal Positioning

For the most effective results, utilize the Gasspringsshop online calculator. This tool will take into account the length and position of the gas strut based on your specific calculations, providing a refined and ideal mounting position.

Adhering to these steps and utilizing the proper tools will guarantee that your gas struts are positioned for optimal performance and durability in any application.

How to Calculate Gas Strut Position

Calculating the correct position for gas struts is essential for optimal performance and longevity. Begin by identifying the moving mounting point, which is typically placed at about 1/3 the length of the lid from the hinge.

Using the Rule of Thumb

For a quick estimation, mount the gas strut approximately 30% of the lid's length measured from the hinge. Ensure the gas strut is mounted with the rod facing downwards to maintain functionality.

Detailed Calculations with Tools

To determine the ideal gas strut mounting position for both static and dynamic applications, utilize the Gasspringsshop calculator tool. This tool accurately calculates essential metrics and displays the mounting positions, ensuring you achieve both functionality and reduced handling forces.

Considerations for Effective Mounting

Place the moving mounting point to create an over-centre condition when the lid is closed. This prevents the lid from "bottoming out" and reduces the handling force required to operate the lid, enhancing usability and safety.

Calculating Gas Strut Position: Practical Examples

Example 1: Standard Cabinet Door

Calculate the gas strut position for a cabinet door with a height of 800mm and a desired opening angle of 90 degrees. Assume the pivot point is at the top. Place the strut 200mm from the hinge along the door, using the formula L = (H/2) / cos(θ) where L is the length from the pivot to where the strut connects, H is door height, and θ is half the opening angle.

Example 2: Car Trunk Lid

For a trunk lid width of 1500mm, aiming for a maximum opening of 70 degrees, attach the strut 300mm from the hinge side. Calculate the optimal attachment point on the lid using L_2 = L_1 tan(θ) where L_1 is the distance from the hinge to the attachment bracket on the car body, L_2 is the distance from the hinge to the brace on the trunk lid, and θ is the angle of lift.

Example 3: Overhead Storage Bin

To support an overhead bin lid measuring 1000mm, with a required opening of 75 degrees, mount the strut 250mm away from the hinge. Use the formula X = H - (H cos(θ)) where X is the distance from the pivot point along the lid where the gas strut needs to mount, and H is the length of the lid.

Example 4: Adjustable Display Stand

For an adjustable display stand with a screen height of 1100mm, position the gas strut 400mm from the stand's pivot to obtain a flexible angle setting. Employ the formula X = H/2 - (H/2 * cos(θ)) for optimal range of motion, where θ changes with the desired screen angle.

Example 5: Folding Workbench

On a folding workbench with a tabletop length of 1200mm, place the gas strut 500mm from the pivot. This calculation uses D = L (1 - cos(θ)) for determining the deposition depth D, where L is the total length and θ the opening angle required.
