Hello how is the Point-Torque computed in template brake_system_4Wdisk in acarshared database?
i.e. Point torque for left front actuator is defined:
2.0*pvs_front_piston_area
*IF(pvs_brake_reduction:0,pvs_front_brake_left_side_bias,left_reduction)
*pvs_front_brake_bias
*VARVAL(cis_brake_demand_adams_id)
*demand_to_authority_scale
*force_to_pressure_cnvt
*pvs_front_brake_mu
*pvs_front_effective_piston_radius
*STEP(VARVAL(left_front_wheel_omega),-velocity_step_threshold,1,velocity_step_threshold,-1)
with units involved according parameter variables and variables:
2.0*pvs_front_piston_area [mm2]
*IF(pvs_brake_reduction:0,pvs_front_brake_left_side_bias,left_reduction) [-]
*pvs_front_brake_bias [-]
*VARVAL(cis_brake_demand_adams_id) [%]
*demand_to_authority_scale [-]
*force_to_pressure_cnvt [-]1/mm2
*pvs_front_brake_mu [-]
*pvs_front_effective_piston_radius [mm]
*STEP(VARVAL(left_front_wheel_omega),-velocity_step_threshold,1,velocity_step_threshold,-1)
force_to_pressure_cnvt is defined as unitless, but force_to_pressure_cnvt=(0.1(1/mm**2))
Adams Car Help says:
As far as I know brake demand is used as percentage value, not force.
also in help is written:
but in template pvs_max_brake_value is defined as Force
Thanks for reply
