35.2. HAT Type B

The schematic diagram of the Type B analysis model is shown in Figure 35.11.

  • The check ball is acted upon by the spring force and the hydraulic force from the cylinder.

  • The motion of the check ball is also assumed to act in the same direction as the cylinder.

  • The check ball is contacted to the cylinder.
