Gas Spring Force Calculator: How to Use It [Step-by-Step]

Understanding Gas Spring Force and Why You Need a Calculator

Gas springs, also known as gas struts or gas dampers, are essential components in various applications, providing controlled motion and support for lids, hatches, and panels. Determining the correct force for a gas spring is crucial for ensuring smooth operation and preventing issues like lids slamming shut or being too difficult to open. A gas spring force calculator simplifies this process, but understanding how to use it effectively is key. Using one ensures you get the right gas strut first time, instead of guessing.

What Does a Gas Spring Force Calculator Do?

A gas spring force calculator takes several input parameters related to your application—including the weight of the lid, its dimensions, and the mounting position of the strut—and calculates the required force in Newtons (N) to properly support and control the movement of the lid. This eliminates guesswork and helps ensure that the selected gas spring provides the optimal level of assistance.

Why Can’t I Just Guess the Force?

Guessing the appropriate force for a gas spring can lead to several problems. If the force is too low, the lid may not stay open or may close unexpectedly. If the force is too high, the lid may be difficult to close, or the gas spring could be damaged prematurely. Accurate calculation ensures user safety and prolongs the lifespan of the components. Using a calculator removes the guesswork.

This guide will walk you through the steps of using a gas spring force calculator and explain the key parameters you need to measure and input for accurate results. We’ll use the Aritech Gas Springs force calculator as an example, which you can find here. Let’s get started!

Step-by-Step Guide: Using the Aritech Gas Springs Force Calculator

The Aritech Gas Springs force calculator is designed to be user-friendly, but understanding each input parameter is essential for accurate results. Here’s a step-by-step guide to using the calculator effectively.

Before you start using the calculator, you need to gather some key measurements related to your application. These measurements include the weight of the lid or panel, its dimensions, and the mounting positions of the gas spring.

Measuring the Weight of the Lid or Panel

The weight of the lid or panel is a critical factor in determining the required force of the gas spring. Use a reliable scale to measure the weight accurately. If the lid is an irregular shape, you may need to estimate the weight by breaking it down into smaller, more manageable sections. Accurate weight measurement is essential for the calculator’s precision.

Measuring the Dimensions of the Lid or Panel

You will need to measure the length and width of the lid or panel. These measurements are used to calculate the center of gravity, which is another important factor in determining the required force. Use a measuring tape or ruler to get accurate dimensions. Record these values in millimetres (mm) to ensure compatibility with the calculator.

Determining Hinge and Mounting Positions

The positions of the hinges and the mounting points of the gas spring are crucial for calculating the leverage and force required. Measure the distance from the hinge to the mounting point on the lid and the distance from the hinge to the mounting point on the frame or body. These measurements should also be recorded in millimetres (mm). Make sure these points are as precise as possible.

Step 2: Access the Aritech Gas Springs Force Calculator

Open your web browser and navigate to the Aritech Gas Springs website and go directly to the Gas Spring Force Calculator page. The calculator interface is designed to be intuitive, with clear labels for each input parameter. Familiarise yourself with the layout before entering your measurements.

Step 3: Enter the Lid or Panel Weight

Locate the input field for the weight of the lid or panel. Enter the weight you measured in Step 1. Ensure that you are using the correct unit of measurement (kilograms or pounds) as specified by the calculator. Double-check the entered value to avoid errors. This is a critical value for accurate force calculation.

Step 4: Enter the Lid or Panel Dimensions

Input the length and width of the lid or panel into the designated fields. Again, ensure that you are using the correct unit of measurement (millimetres or inches) as specified by the calculator. Accurate dimensions help the calculator determine the center of gravity and leverage accurately. These dimensions are used to calculate the effective lever arm.

Step 5: Enter Hinge and Mounting Positions

Enter the distances from the hinge to the mounting point on the lid and the distance from the hinge to the mounting point on the frame or body. These measurements are essential for calculating the angle and leverage of the gas spring. Double-check these values to ensure they are accurate, as small errors can significantly impact the results. Incorrect hinge and mounting positions can lead to inaccurate force calculations and improper gas spring selection.

Step 6: Specify the Mounting Angle

The mounting angle of the gas spring also affects the force calculation. If the gas spring is mounted at an angle relative to the lid or frame, enter the angle in degrees. If the gas spring is mounted parallel to the lid or frame, the angle is 0 degrees. Accurate angle input ensures proper force calculation and optimal gas spring performance. This angle is crucial for accurately calculating the force components.

Step 7: Calculate the Required Force

Once you have entered all the necessary parameters, click the “Calculate” button. The calculator will process the information and display the required force in Newtons (N). This is the force that the gas spring needs to exert to properly support and control the movement of the lid or panel. Review the results carefully to ensure that they are within a reasonable range.

Step 8: Select a Gas Spring with the Appropriate Force Rating

Now that you have the required force, you can select a gas spring with a force rating that matches or is close to the calculated value. It’s often better to choose a gas spring with a slightly higher force rating to ensure that the lid or panel stays open securely. Browse the Aritech Gas Springs product catalog or contact their technical team for assistance in selecting the right gas spring for your application. Selecting a gas spring with an appropriate force rating is crucial for optimal performance and safety.

Use Consistent Units of Measurement

Make sure you are using consistent units of measurement throughout the calculation process. If the calculator requires measurements in millimetres, ensure that all your measurements are in millimetres. Mixing units can lead to significant errors. Consistent units prevent calculation mistakes and ensure reliable results.

Account for Additional Weight

If there are any additional components or accessories attached to the lid or panel, such as handles, latches, or insulation, account for their weight in the calculation. Additional weight can affect the required force of the gas spring. Include all relevant weight for accurate force calculation.

Consider the Operating Environment

The operating environment of the gas spring can also affect its performance. Extreme temperatures, humidity, or exposure to corrosive substances can impact the gas spring’s lifespan and force output. Consider these factors when selecting a gas spring for your application. Harsh environments may require specialized gas springs with corrosion-resistant or high-temperature seals.

Troubleshooting Common Issues

Even with careful measurements and accurate inputs, you may encounter some issues when using the gas spring force calculator. Here are some common problems and how to troubleshoot them:
