◉ Introduction and objectives:
In this article, we will briefly explain the suspension system for boats and ships.
The initial idea for this system was formed in 2004 when I was in Dubai for an art exhibition. At that time, I had bought a model of an electric car (toy) with a very complex suspension system. The smooth and floating movement of the car's suspension aids had a full 180-degree function in all horizontal and vertical axes and I was really amazed by this complex and unique engineering on a toy scale. The perfect suspension performance of that toy gave me the initial idea of using a similar system on water waves and after ten years, I designed that idea theoretically and used and demonstrated it in my fifth science fiction film "Mission 411" sponsored by Da Yamms Entertainment in Hollywood, USA, 2014 . Years later, I realized that the anti-shock ship I created in this film had the potential to be patented as a real-world invention at that time so, I dedicate this article to re-explaining my old design for that system (without new revisions).

In maritime traffic, the smaller the boat or ship, the more vibration it has due to the rising and falling of waves because according to the laws of physics, if the surface dimensions of two objects are closer together, then the two objects will have a greater kinetic influence on each other and if the surfaces of two objects have different dimensions, then the effect of the two objects' motion on each other becomes inverse and variable, in proportion to their dimensions and mass. At the same time, this issue is also directly related to the density of the object, because if the density of the object is less than the density of water, the intensity of the shaking increases and if the density of the object is the same as water, the mass is submerged and is less affected by the movement of the waves. For example, if the outer surface of a small wave in the sea is one square meter and the surface area of the object lying on the wave is the same as the wave and has a lower density than the mass of water and all other things being equal then, the effect of the wave's shock on the object will be complete. This means that as the wave rises or falls, the object follows the wave.

For example, if the outer surface of the wave is one square meter and the surface of the object is 10 square meters with a density lower than the mass of water, only a portion of the object's surface is affected by the wave's momentum due to the lack of physical overlap between the object's surface and the wave's surface. If the surface area of an object reaches 100 square meters and has the same density as water, then the object's impact on the wave is almost minimal, and this is the reason why ships and tankers remain stationary when faced with small and medium waves. Waves come in many forms, and their intensity and height depend on various factors such as wind speed, depth of the water bed, variable water temperature from the magma core on the sea floor, or sudden movements on the sea bed. In each of these cases, waves are created by different physical oscillations, causing mild to severe shaking with different amplitudes and periods.

It is clear that the oscillating motion of a boat or ship going up and down over a long period of time and in a repetitive manner is never pleasant. These wave fluctuations cause problems such as nausea, headaches, and pain in the spine and neck, for those who are not used to being floating and submerged in a boat for long periods of time. Given my residence in a coastal city and frequent use of marine traffic, these challenges led me to create the idea of using a suspension system for boats and sea buses in those years.
◉ Technical description of the invention:
As can be seen in the computer simulation (video at the end of this article), I used 12 hybrid hydraulic jacks to support and suspend a sea bus hull. Using these jacks, the deck of a boat or sea bus is fixed and motionless on the water when facing the wave impulse. The number of jacks required to apply the suspension system in such a design depends on the weight of a boat or sea bus so, the larger and heavier hull, the more jacks will be needed. Although with the new revision, linear and mono-skeleton suspensions can be used to replace this old design but this design still has high potential for flexibility and good responsiveness to fast wave movement.

To prevent the reaction of the boat's cabin body to the wave surface, the height of each jack is approximately 1 meter and 30 centimeters, because this height helps the mechanical and hydraulic arm of each jack to be flexible and operate 90 degrees in the horizontal and vertical axes. The base of all 3 mechanical arms is mounted on a holding pull to allow the cabin to be placed in a safe position using 12 hydraulic-mechanical arms on 4 holding pulls.

The material composition of the holding pulls is made of compressed polyethylene, which allows air to be compressed inside each pan using a 4-wall structure. This material has properties such as; fine, compact and light cellular texture - Rotational molding - high resistance to the destructive properties of sodium cations found in salty sea water - as well as resistance to the destruction of the pull's texture and shape by intense solar radiation. This combination of lower density (compared to seawater) with internal compressed air creates anti-sinking and anti-overturning properties (without the risk of water penetrating the pull). The maximum longitudinal and transverse dimensions of each pull are designed in such a way that there is no intersection or collision between them, because this prevents the pulls from colliding with each other, provides the largest surface area of contact between the pull and the wave surface, and minimizes reactivity to small wave fluctuations.

According to the images attached to this article, each hydraulic two-way jack (suspension system) consists of 5 main parts that are connected to each other by bearings and gears. These parts include the jack connection base to the bottom of the passenger cabin, the parent mechanical arm lever, the child mechanical arm lever, the jack end connection base to the surface of the floating pull in the water, and the oil and air inlet and outlet piston. In this type of jack, the force of the sea waves is needed to retract and open the piston. In other words, as the wave rises, the levers of the mechanical arm connected to the piston close, and as the wave descends, these levers open along the linear path of the piston. The function curve of the opening and closing of the parent and child mechanical arms causes the jack levers to operate at a 90-degree angle to the oscillation of the waves.

The sequential arrangement of 3 hydraulic jacks on each pull is to distribute and disperse the pressure exerted by the wave oscillations on the surface of the pull and prevent the pull from overturning or deflecting. In the situation of facing wide waves, if the lateral and longitudinal distance of the pulls is greater than each other, the pressure exerted by the wave oscillation on the jack seat arm will decrease and if the distance between the pulls is shorter, the pulls will follow the width of the waves more and the up and down oscillation of the passenger cabin will increase, so creating the appropriate distance and dimensions for each pull plays a fundamental role in the proper functioning of the suspension system.
One of the advantages of using a hydraulic jack suspension system is that it does not follow the stereotypical and common design in building a boat or a sea bus. Placing the passenger cabin on the base of the hydraulic jack suspension levers eliminates the limitation and dependence on aerodynamic structures for cabin design. In other words, by separating the passenger cabin and the boat's hull, we can achieve greater innovation and creativity in cabin design.
