Sympy: Mecanica, Ejemplo de oscilador con un pendulo

 

Oscilador Duffing con un péndulo

En este ejemplo demostramos el uso de la funcionalidad proporcionada en sympy.physics.mechanics para derivar las ecuaciones de movimiento para un sistema que consiste en un oscilador con un péndulo. Este ejemplo está inspirado en el Documento [P.Brzeskia2012] Sección 2. 

  

El sistema se modelará con las ecuaciones de LaGrange. M, es masa del oscilador de duffing, m, es masa del péndulo,  l, es longitud del péndulo. k1 y k2,  son lineales y partes no lineales de la rigidez de la primavera, y c1, es un coeficiente de amortiguación viscoso del oscilador de duffing.  

>>import sympy as sm
>>import sympy.physics.mechanics as me
>>me.init_vprinting()

Definir variables 

>>M, m, l, k1, k2, c1, g, h, w, d, r = sm.symbols('M, m, l, k1, k2, c1, g, h, w, d, r')

>>q1, q2 = me.dynamicsymbols('q1 q2')

>>q1d = me.dynamicsymbols('q1', 1)

• h: altura del oscilador de Duffin

• w: ancho del oscilador de Duffin

• d: Profundidad del oscilador Duffing 
• r: Radio del enorme bob del péndulo  
• q1: Coordenada generalizada que representa la posición del oscilador de Duffing  
• q2: Coordenada generalizada que representa el ángulo del péndulo  

Definir cinemática

Defina todos los marcos y puntos de referencia.

>>N = me.ReferenceFrame('N')

>>B = N.orientnew('B', 'axis', (q2, N.z))

La velocidad angular del péndulo en el marco de referencia es:

>>B.ang_vel_in(N)
>>q2'(t) n_z

Las ubicaciones y las velocidades del bloque de osciladores de Duffing y el péndulo son:

>>O = me.Point('O')

>>block_point = O.locatenew('block', q1 * N.y)

>>pendulum_point = block_point.locatenew('pendulum', l * B.y)

O es un punto fijo en el marco de referencia inercial.

>>O.set_vel(N, 0)

>>block_point.set_vel(N, q1d * N.y)

>>pendulum_point.v2pt_theory(block_point, N, B)
>>q1'(t) n_y + -l*q2'(t) b_x

Definir inercia y cuerpos rígidos. Aquí, asumimos un péndulo simple que consiste en un bob de masa m colgando de una cadena de longitud sin masa l y fijado en un punto de pivote (bloqueo del oscilador de duffing).

>>I_block = M / 12 * me.inertia(N, h**2 + d**2, w**2 + d**2, w**2 + h**2)

>>I_pendulum = 2*m*r**2/5*me.inertia(B, 1, 0, 1)

>>block_body = me.RigidBody('block', block_point, N, M, (I_block, block_point))

>>pendulum_body = me.RigidBody('pendulum', pendulum_point, B, m, (I_pendulum, pendulum_point))

Definir fuerzas

Calculamos las fuerzas que actúan sobre el sistema. En este ejemplo, establecemos la energía potencial en cero en el lagrangiano e incluimos el Fuerzas conservadoras (gravedad y resorte de muescas) en las cargas.

>>path = me.LinearPathway(O, block_point)

>>spring = me.DuffingSpring(k1, k2, path, 0)

>>damper = me.LinearDamper(c1, path)

>>loads = spring.to_loads() + damper.to_loads()

>>bodies = [block_body, pendulum_body]

>>for body in bodies:

>>    loads.append(me.Force(body, body.mass * g * N.y))

>>loads
            /      _____           3/2\                  /        _____           3/2\

                    _____                                         _____
                   /   2                                         /   2

Con la configuración del problema, se puede calcular el Lagrangiano y se forman las ecuaciones de movimiento.

TESPy: Modelado de sistemas termicos basicos, Bomba de calor.

 

 

Fig1. Topología típica de una bomba de calor 

Este tutorial es la continuación del tutorial de la introducción . Primero, revisaremos las opciones de especificación y la flexibilidad de modelado en TESPy, así como algunos errores típicos que pueden ocurrir al usar el software. A continuación, realizaremos un análisis simple del COP de la bomba de calor basado en varios parámetros de entrada.

Descargue el guión completo aquí:heat_pump.py

Flexibilidad en el modelado

En TESPy las especificaciones de componentes y/o conexiones son intercambiables en todas las formas posibles, siempre que el sistema de ecuaciones que representa la planta esté bien definido.

Por ejemplo, en lugar del calor proporcionado por el condensador, podríamos especificar el caudal másico m del refrigerante. Para anular la configuración de un parámetro, debe establecerse en None. Para sustituir la especificación, establezca el caudal másico de la conexión c1 en 5 kg/s:

>># en los parametros iniciales habiamos indicado el Q en el condensador como

>># co.set_attr(pr=0.98, Q=-1e6))

>># ahora vamos a eliminar ese calor

>>co.set_attr(Q=None)

>>c1.set_attr(m=5)

>>my_plant_one.solve('design')

>>my_plant_one.print_results()

Se puede observar que el calor transferido por el condensador ahora es resultado del flujo másico especificado. Podríamos hacer algo similar, por ejemplo, con la temperatura del disipador de calor. La especificamos en nuestra configuración inicial. Ahora queremos insertar un compresor con una relación de presión de salida a entrada fija. En ese caso, no podemos elegir la temperatura de condensación, pero será resultado de esa especificación:

Errores típicos

Si sobrevalora o subestima el sistema especificando muy pocos o demasiados parámetros, recibirá un mensaje de error. Podríamos configurar la demanda de calor y el caudal másico simultáneamente.

Atención

¡Los dos ejemplos de código de esta sección no están incluidos en el script descargable!

>>co.set_attr(Q=-1e6)
>>c1.set_attr(m=5)

>>my_plant_one.solve('design')

Error

ERROR:root:You have provided too many parameters: 20 required, 21 supplied. Aborting calculation!
Traceback (most recent call last):
File ".\tutorial\basics\heat_pump.py", line 59, in <module>

tespy.tools.helpers.TESPyNetworkError: You have provided too many parameters: 20 required, 21 supplied. Aborting calculation!

Si se realiza una especificación que resulta en la cantidad correcta de parámetros, pero causa una dependencia lineal en el sistema de ecuaciones, el mensaje de error no será tan claro. Para un ejemplo sencillo, podemos establecer el caudal másico en las conexiones 1 y 2 sin establecer la demanda de calor ni la temperatura de evaporación. En este caso, el número de ecuaciones será correcto, pero la especificación, obviamente, carecerá de sentido.

>>co.set_attr(Q=None)
>>c1.set_attr(m=5)
>>c2.set_attr(m=5, T=None)

>>my_plant_one.solve('design')

Error

ERROR:root:Singularity in jacobian matrix, calculation aborted! Make sure your network does not have any linear dependencies in the parametrisation. Other reasons might be
-> given temperature with given pressure in two phase region, try setting enthalpy instead or provide accurate starting value for pressure.
-> given logarithmic temperature differences or kA-values for heat exchangers,
-> support better starting values.
-> bad starting value for fuel mass flow of combustion chamber, provide small (near to zero, but not zero) starting value.

Para obtener información más detallada sobre la cantidad de variables involucradas y las formas de especificación de parámetros, vaya a la sección de módulos TESPy dentro del capítulo Documentación.

Otra causa frecuente de estos errores son los valores iniciales incorrectos. Tenemos un tutorial dedicado específicamente a este tema aquí .

Análisis paramétrico del COP

Para una cantidad constante de producción de calor, investigaremos la influencia de

• el nivel de temperatura de la fuente

• El nivel de temperatura del fregadero y

• la eficiencia isentrópica del compresor.

Para ello, importamos los paquetes numpy y matplotlib, definimos los rangos y, a continuación, iteramos sobre un bucle y reiniciamos la simulación para cada parámetro de entrada. Tras cada bucle, restablecemos el valor original del parámetro correspondiente. Recopilamos los resultados en listas y, finalmente, podemos crear un diagrama de dispersión con matplotlib.
