msc_truck_leaf_tandem_susp_fore
Overview
This template represents the solid axle leaf spring type suspension. This template is identical to the msc_truck_steer_suspension template except for the addition of a leaf spring, tandem axle equalizer unit, and optional panhard rod and trailing arms.
Template name

Major role

Application

Description
This template represents the combination of msc_truck_steer_suspension and a leaf spring.
In addition, this template includes an equalizer unit. The equalizer unit contains an equalizer part, hanger, and shackle strap.
An equalizer is used for multi-axle or tandem axle suspension systems. The basic function of an equalizer is to transfer load from the heavily loaded axle to the lightly loaded axle in bump or rebound condition. The transfer of load serves to equalize the weight being carried by all axles at the time of impact.
An equalizer allows for a smooth transfer of loads through the suspension system. Without an equalizer, going over a bump would cause one axle to carry a disproportionate amount of weight.

Topology
The topology is identical to the msc_truck_steer_suspension and msc_truck_leaf_spring template, except for the addition of an equalizer unit, and optional panhard rod and trailing arms.
You can set subsystems based on this template to Steerable axle or Non-Steerable axle using pvs_steerable_axle parameter variable. When pvs_steerable_axle parameter variable is set to 1, Adams Car activates tie rod part and dependent joints and deactivates the upright lock motion.

Topology
The re-circulating ball steering gear consists of three major parts:
â– Input shaft
â– Ball screw
â– Rack
The steering wheel rotates the steering input shaft. The steering input shaft attaches to the ball screw through a torsion bar. The ball screw imparts translational motion to the rack, through a coupler. The rack, in turn, rotates the pitman arm through a coupler.
The pitman arm drags the steering link and steering input arm, which is directly connected to the left wheel, which pulls the tie rod, connected to the right wheel.

msc_truck_steer_suspension
Overview
This template represents a steerable solid axle front suspension of a truck, and is meant to be used in conjunction with a separate template containing springs, such as _msc_truck_leaf_3link.tpl or _msc_truck_leaf_spring.tpl.
Template name
_msc_truck_steer_suspension
Major role
Suspension
Application
Suspension and Full-vehicle analysis
Description
The template forms the steerable front suspension. The tie rod, steering arm and axle forms a four bar chain with two revolute and two spherical joints. The suspension upright forms the wheel carrier part. The solid axle in turn supports leafspring suspension and dampers. The steering input arm (in steering subsystem) connects to the left suspension upright.

Overview
This template represents the solid axle suspension typically used on tractors.
Template name
_msc_truck_drive_axle
Major role
Suspension
Application
Suspension and Full-vehicle analysis
Description
The template is used in conjunction with the dual tire template in the tractor assembly as the driving solid axle. Longitudinal load is reacted by the rigid hockey sticks, and lateral load is reacted by the panhard rod. Drive torque left and right are applied as rotational single component forces between hub parts and the solid axle. A simple model of a limited slip differential is also included in this suspension template. There are no rigid parts or gears in the axle differential unit: a differential torque is transferred from one hub to the other depending on the difference of the wheel rotational speeds. The rotational speeds of the left and right half shafts are computed in a user defined solver variable and their difference is used as an independent variable in the akima interpolation of the limited slip differential spline. An input communicator of type solver variable receivers the total axle torque. That value, corrected with the appropriate differential torque, is then referenced in the two joint force actuators. The joint force actuators produce the driving torque between the rotating hub parts and the solid axle.

msc_truck_wheels_dual
Overview
The dual wheel template represents a dual wheel arrangement on drive and trailer axles of the truck. It uses the tire property file and supports three basic functions:
â– Supports vertical load
â– Develops longitudinal forces for acceleration and braking
â– Develops lateral forces for cornering
Template name
_msc_truck_wheel_dual
Major role
Wheel
Application
Full-vehicle analyses
Description
The dual wheel system template consists of wheel parts rigidly connected to mount parts. The tire contact patch forces are transformed in forces and torques applied at the hub. A series of user-written subroutines perform the force calculation depending on the tire property file that you selected. The road property file determines the road contact model. For additional information about using tire and road models, see the Adams Tire online help.
Files referenced
The wheel system template references a tire property file for each wheel part. The default tire property file is msc_truck_fiala.tir, stored in the tires.tbl directory of the Adams Car Truck shared database.
Topology
The outside and inside wheel are rigidly connected by fixed joint, and the inside wheel in turn is connected to spindle.
Communicators
Mount parts provide connectivity to the suspension subsystems, and output communicators publish information about tire forces and wheel orientation. Tire force output communicator is used by the drive axle template in order to evaluate the halfshaft angular velocity during a quasi static analysis. The halfshaft velocity contributes to the calculation of the engine speed during quasi-static analysis.

msc_truck_brake
Overview
The tractor disc-brake system template represents a device that applies resistance to the motion of a vehicle.
Template name
_msc_truck_tractor_brake
Major role
Brake_system
Application
Full-vehicle (tractor only) analysis to simulate the effect of braking on the dynamics of the vehicle.
Description
The disc-brake system template represents a simple model of a brake system. It applies a rotational torque between the caliper and the rotor. A pair of disc brakes is mounted on each axle. The brake line pressure is divided into two channels, front and rear, depending on the brake_bias. This brake line pressure is converted to brake torque depending upon the brake_demand, coefficient of friction, effective piston radius and the velocity of the vehicle.
Files referenced
None
Topology
The rotor is rigidly attached to the wheel. A caliper is fixed to the suspension, housing any number of pistons, the effective area of which is specified as a parameter. The brake bias determines the amount of braking line pressure distributed to each axle. Effective piston radius and the friction coefficient are used to convert the brake line pressure into braking torque. The disc-brake template is a simple model of a brake system. It does not model the complex interaction between the rotor and caliper.

msc_truck_powertrain
Overview
This template represents the powertrain including the clutch and gear box.
Template name
_msc_truck_powertrain
Major role
powertrain
Application
Full-vehicle analysis
Description
The powertrain template is functional representation based on an internal combustion engine, clutch and a gearbox model. The engine combustion model takes the throttle demand and produces a crankshaft torque as a result of a three dimensional spline interpolation. Independent variables are engine RPM and throttle position. Torque is divided with inter- and intra-axle differentials.

Topology
The powertrain produces a transmission output torque acting on the front driveshaft, reacted on the powertrain part. The front driveshaft drives a coupler splitting torque between the front and rear axles. The front and rear axles then split torque left and right through differentials.
