Arguments
- bush_name
- The variable name of an existing bushing pair.
- LEFT RIGHT
- If LEFT is specified, the properties are assigned to the left bushing, and the right bushing properties are made symmetric to the left bushing.
- k_x, k_y, k_z
- Translational damping in the X, Y, and Z directions.
- c_x, c_y, c_z
- Translational stiffness in the X, Y, and Z directions.
- kt_x, kt_y, kt_z
- Torsional stiffness in the X, Y, and Z directions.
- ct_x, ct_y, ct_z
- Torsional damping in the X, Y, and Z directions.
- f_x, f_y, f_z
- Initial translational force in the X, Y, and Z directions.
- t_x, t_y, t_z
- Initial torque in the X, Y, and Z directions.
- `expression`
- An expression for a stiffness or damping token.
- curve_name, AKIMA|CUBIC|LINEAR, `indep_variable`
- When using curve data, a curve, interpolation method, and an independent variable must be specified, where curve_name is the variable name of an existing curve, the interpolation method can be set to AKIMA, CUBIC or LINEAR and the independent variable is specified in Templex syntax.
Example

b_lca,
b_frame,
p_lca_frnt_bush)

Context
Comments
To specify non-linear properties for stiffness or damping in any direction, a solver expression or curve data can be used to compare the force. When using a solver expression, Templex syntax is used and all variables are enclosed in braces {} and the rest is treated as literal. To use curve data, a curve, interpolation method, and a independent variable must be specified, for example, CRV, curve_name, AKIMA, `{DX}`where curve_name is the variable name of an existing curve, interpolation method can be set to AKIMA, CUBIC or LINEAR and the independent variable is specified in Templex syntax.
