    Selection Supporting Information

    ■Oil shock absorber is a shock absorber that
    primarily uses oil. Compared with other cushioning materials (rubber, spring, air, etc.), they are compact and capable of repeatedly absorbing large impact energy
    softly without rebound. Internal structure and basic principle of oil type shock absorbers are shown as follows.
    When an object collides with a piston rod, the oil in the pressure chamber is compressed by a piston.
     The clearance between inner tube and piston is so small that compressed oil is forced out of the orifices.
     At this point, the impact energy is converted into heat energy by dynamic resistance.

    The piston rod sinks into the shock absorber body so that the oil equal in volume to the piston
    moves into the accumulator.
      This mechanism provides an ideal shock absorbing action.
    Various absorption characteristics can be obtained depending on the number and size of orifices.
    (Refer to classification according to absorption characteristics structures.)
    Please note that when the wrong collision speed is selected, some abnormal reaction may occur during collision or the impact energy may not be absorbed in an ideal manner.
      
    ■Procedure of Selection
    (1) Calculation of inertial energy (E1 ) 
    According to examples of calculation for selection, calculate inertial energy based on collision mass (m), collision velocity (V)
    ·moment of inertia (I) and collision angular velocity (ω).

     

    (2) Calculation of additional energy (E2') 
    Confirm whether there is propulsion (F) or not and calculate the
    additional energy according to Examples Of Calculation For Selection.

     

    (3) Temporary decision of absorber stroke 
    Obtain the temporary stroke (S') based on Fig. 1.

     

    (4) Calculation of total energy 
    Calculate the total energy from the sum of inertial energy (E1) and additional energy (E2 ').

     

    (5) Select absorption characteristics structures from energy ratio 
    Select an orifice type from Fig. 2 temporarily.

     

    (6) Check max. absorbed energy per minute 
    Calculate the energy (ET) per minute from the operating cycle (cycle/min) and total energy, and confirm whether or not the value is within the possible operating range.

     

    (7) Check equivalent mass 
    According to examples of calculation for selection, calculate the equivalent mass and confirm whether it is less than the max. equivalent mass in the catalog (me').
     

     

     

    Calculate the temporary stroke S' with the Inertial Energy E1 (Adjustable / Fixed Force Type)

     

    Fig. 2 Select the orifice type from energy ratio (additional energy E2' / inertial energy E1)

    ■Shock Absorbers Classification according to absorption characteristics structures
    Structure
    Adjustable
    Fixed Force Type
     
    Tapered orifice
    S Type
    A Type
    B Type
    L Type
     There are three types of tapered orifices; a dashpot structure using a clearance between the piston and cylinder tube, a single-tube structure with an orifice in the piston, and a double-tube type tapered orifice, all of which exhibit similar drag force characteristics.
     
     
     The piston slides in a cylinder tube filled with oil, and a tapered orifice is installed in this piston.
    Because the orifice area is constant over the entire stroke, as the shock absorption characteristics shown in the right graph, the resistance is the largest immediately after a collision but gradually reduces speed as the stroke continues.
     
     
    Irregular Multi
    Orifice
    Medium Speed
    Type M
     In this double-tube structure, the piston slides the
    inner wall of the inner tube. This inner tube has several orifices along the
    direction of strokes, and not constant damping, but
    absorbs energy depending on various purposes. It is designed to absorb kinetic energy during the first half of stroke and
    control speed during the second half. Therefore, it is well suited to
    absorb energy against air cylinder thrust.
    Multi
    Orifice
    High Speed
    Type H
     In this double-tube structure, the piston slides in the
    inner tube. This inner tube has several orifices along the direction
    of strokes. Because the orifice area
    becomes small gradually as the stroke speed slows down, the drag force fractures but the maximum drag is
    lower.
    [ ! ] Adjustable Type No.0806M is single orifice structure and No.3625 L Type is multi-orifice structure.
    * When using shock absorbers (fixed force type) in parallel, calculate the total energy as shown below.
      E = E'/n
      E: Energy acting on each shock absorber
      E’: Total Energy
      n: Number of shock absorber receivers
    * Do not use adjustable type shock absorbers in parallel.

    App. Example

    • The shock absorber cannot be used at full stroke.
      If used at full stroke, there is a possibility of damage.
    • Install so that the object stops at a distance of 1 mm or more from the stroke end, or install an external stopper as required.
      Stopper nuts also can be used.

    Cautions on Use

    ■ Precautions for Use
    • Shock absorbers use oil internally, and seals are used to prevent oil from leaking to the outside, but a perfect seal cannot be guaranteed.
      Because of this, it cannot be used in environments that prohibit oil.
    • Check for oil leaks and the return status of the piston rod. If leaking of a large amount of oil or failure of returning piston rod are found, there
      may be some abnormality and it should be replaced. If you use a defective product, it may cause damage to the unit to which it is installed.
    • With the number of uses, the energy absorption capacity will decrease due to the reduction in internal oil and wear of parts. Taking this into account, we recommend selecting a size that has at least 20 to 40% margin for the maximum absorbed energy.
    • The performance and functionality of shock absorbers may deteriorate depending on the load. Perform daily inspections to ensure that the required functions are met and to prevent accidents from occurring.
