Control of a Single-Component Vaporizer

2010-03-01T05:00:00

A single component vaporizer with separate feed and heat controller to regulate the mass of fluid and temperature inside the vessel. The physical model includes custom components that calculate:

A mass balance

A heat balance

The specific enthalpy of the outlet vapour stream

The temperature in the vesse

The pressure in the vessel

The rate of vapour outflow

Variable Inertia

2010-02-22T05:00:00

This is a model of a shaft with an angle-dependent inertia. The VariableInertia custom component implements Newton's Second Law for a rotating body given a time-dependent inertia and an initial angle. A lookup table provides the inertias specified every 30 degrees, and the 1D Lookup Table component smoothly interpolates between these points. A step torque causes the shaft to rotate, and its angular velocity changes due to the variable inertia.

Wedge Component

2010-02-22T05:00:00

Models the action of two frictionless wedges sliding against one another and defined by the slope between them

Electronic Wedge Brake

2010-02-22T05:00:00

A 12V DC motor is connected to a worm gear that pushed on the side of a wedge. The force and displacement of the wedge are directed 90-degrees towards the brake pad surface. The slope of the wedge determines the force and displacement ratio. The brake pad is modeled as a mass-spring-damper in contact the rotor, which is modeled as translational ground. The force applied to the rotor is measured with the Force Sensor component measures the applied force and provides this as the force input to the Brake component. A rotational inertia with an initial rotational speed is attached to the brake. At t = 1 sec, the motor is engaged and the braking force stops the wheel.

Ideal Y-Y Three-Phase Rectifier

2010-02-22T05:00:00

This is an ideal Y-Y connected three-phase rectifier. The primary and secondary sides of the transformer are both Y-connected with the star connector to establish ground. The three phases are then sent into the Universal Bridge subsystem, which consists of ideal diodes that perform full-wave rectification of the three phases. The load consists of a resistor and a capacitor. The capacitor filters the ripple present on V+ to provide the resistive load with a more stable voltage.

Mean-Value Internal Combustion Engine Model: Real-Time Execution in NI Veristand™

2010-02-10T05:00:00

This is a version of a MapleSim Mean-value Engine model that has been prepared for export to Simulink®, NI LabVIEW™ and NI VeriStand™ for real-time implementation

Note that to complete the export to the target platform, you will need the corresponding MapleSim connector add-on.

Translational Friction

2010-02-09T05:00:00

The Translational Friction block represents friction in contact between moving bodies.In this example, two models are created of a simple spring-mass-damper. The first example has no friction, the second one has the translational friction custom component.

Rotational Friction

2010-02-09T05:00:00

The Rotational Friction block represents friction between rotating bodies.

Simple Pump with Vertical Pipe

2010-02-09T05:00:00

Model of a centrifugal pump based upon the head/flowrate relationship H(q)=a-b*q^2, where a and b are empirical parameters.

Model of vertical pipe run. Models only the flow against gravity (-g deltaZ), and needs to be connected to an equivalent length of horizontal pipe for frictional effects)

Heat Exchanger Dynamics

2010-02-09T05:00:00

Simplified dynamic model of a heat exchanger, based upon a heat balance across the hot and cold streams, and a simplified temperature difference (temperature of hot stream at entrance – temperature of cold stream at entrance).

Vehicle Model with Double-Wishbone front and Trailing-Arm rear Suspension

2010-02-01T05:00:00

This model represents a vehicle model with double wishbone front suspension and trailing arm suspension in the rear. No CAD file for the chassis has been attached to the model in order to more easily show the deflection of the suspension during the simulation.

Note: Requires MapleSim Tire Component Library.
