Translational Force Balance Model (1 DOF)
The force balance equation for translation motion in one direction is given as:
where,
m
body mass
x
displacement
t
time
Hydrodynamic Force
where,
Fhydronamic
hydrodynamic force
Fpressure
pressure forces
Fshear
shear forces
The Spring Force
where,
Fpreload
preload force
Fspring
spring force
k
spring constant
d
displacement
x0
position of the boundary or volume (during model setup)
Damping Force
where,
Fdamping
damping force
D
damping coefficient
v
component velocity
Additional Force may be added using Additional Force on Body.
Frictional Force
where,
Ffriction
friction force
μ=μstatic
static friction coefficient for a stationary part
μ=μsliding
sliding friction coefficient for a moving part
