Change in shock length per unit vertical displacement of the wheel center relative to the sprung mass.
Computed by:
SVCWSR.
Input Variables Used:
Front and rear compliance matrices.
Shock Body attachement markers
Shock Suspension attachement markers
Method:
SVC calculates a temporary compliance matrix to relate the wheel and shock motion. For full-vehicle models, the body degree of freedom is then removed from the compliance matrix.
Determine the normalized suspension to body vector
LSL = SQRT( LSHOCK(1)**2 + LSHOCK(2)**2 + LSHOCK(3)**2 )
Where:
LSHOCK(1) - Global X displacement of shock attachment on body wrt shock attachement on suspension
LSHOCK(2) - Global Y displacement of shock attachment on body wrt shock attachement on suspension
LSHOCK(3) - Global Z displacement of shock attachment on body wrt shock attachement on suspension
LSHOCK(1) = LSHOCK(1) / LSL
LSHOCK(2) = LSHOCK(2) / LSL
LSHOCK(3) = LSHOCK(3) / LSL
Compute change in shocklength due to vertical force at wheel center (dot product of shock-end compliance and shock vector).
DS = CTEMP(7,3) * LSHOCK(1) + CTEMP(8,3) * LSHOCK(2) + CTEMP(9,3) * LSHOCK(3)
Shock Ratio = CTEMP(3,3) / DS
Shock Ratio = 1/Shock Ratio
