A piston with adjustable resistance?

In summary, the conversation discusses the need for a device that can generate "0" movement, have a shaft that can be manipulated, and can resist external motion. The device should function as an actuator but its purpose is to only resist motion and not generate it. The suggested device is an adjustable rate shock absorber, commonly used in vehicle suspensions.

Dear all,

I have recently come across a project that requires me to find a device that does the following,

A device that:

1)generates "0" movement
2)have a shaft that can be pulled or pushed over a distance
3)I can induce a variable resistance force to the shaft (to counter external motion)

Overall, it should looks like an actuator but the function is different- it can only resist motion and cannot generate motion on its own.

Have you heard of any devices similar?

1. What is a piston with adjustable resistance?

A piston with adjustable resistance is a mechanical device that is used to control the amount of force exerted by a piston. It is commonly used in engines, hydraulic systems, and other machinery where precise control of force is necessary.

2. How does a piston with adjustable resistance work?

The piston with adjustable resistance works by adjusting the level of resistance in the cylinder that the piston moves through. This can be done through various methods, such as changing the size of the orifice or using valves to regulate the flow of fluid. By adjusting the resistance, the amount of force and speed of the piston can be controlled.

3. What are the benefits of using a piston with adjustable resistance?

One of the main benefits of using a piston with adjustable resistance is that it allows for precise control of force and speed in machinery. This can improve the efficiency and performance of the machinery. It also allows for flexibility in different operating conditions, as the resistance can be adjusted accordingly.

4. Is a piston with adjustable resistance necessary in all machinery?

No, a piston with adjustable resistance is not necessary in all machinery. It is typically used in applications where precise control of force is required, such as in engines, pumps, and hydraulic systems. In other machinery where force control is not critical, a standard piston may be used.

5. Are there any disadvantages to using a piston with adjustable resistance?

One potential disadvantage of using a piston with adjustable resistance is that it may add complexity and cost to the machinery. Additionally, if the resistance is not properly adjusted, it can lead to inefficiencies or malfunctions. Regular maintenance and calibration may be required to ensure proper functioning.
