Supply rotation type and order as in orient.

Gives equations relating the qdot’s to u’s for a rotation type. kinematic_equations ( speeds, coords, rot_type, rot_order = '' ) # > from import ReferenceFrame, get_motion_params, dynamicsymbols > from import init_vprinting > init_vprinting ( pretty_print = False ) > from sympy import symbols > R = ReferenceFrame ( 'R' ) > v1, v2, v3 = dynamicsymbols ( 'v1 v2 v3' ) > v = v1 * R. Have a look at the Parameters and Examples for more clarity. This function can also be used for calculating rotational motion To constants by substituting the time values in the dynamicsymbols._t The boundary conditions are also functions of time, they are converted To be zero by default (zero vectors, in case of vectorial inputs). If any of the boundary conditions are not provided, they are taken Timevalue2(for velocity boundary condition). The values of time at which the boundary conditions are specifiedĪre taken from timevalue1(for position boundary condition) and For example, given theĪcceleration, the velocity and position parameters are taken as If a higher order differential function is provided, the lower orderįunctions are used as boundary conditions. Position) as vectorial functions of time in the given frame. Returns the three motion parameters - (acceleration, velocity, and vel ( N ) (Derivative(q(t), t) + 10)*N.x kinematic_equations #. > p = Point ( 'p' ) > q = dynamicsymbols ( 'q' ) > p. Where O and P are both points fixed in frame B, which is rotating in ^N a^P = ^N a^O + ^N alpha^B x r^OP + ^N omega^B x (^N omega^B x r^OP) The 2-point theory for point acceleration looks like this: Sets the acceleration of this point with the 2-point theory. from import Point, ReferenceFrame > from import dynamicsymbols > from import init_vprinting > init_vprinting ( pretty_print = False ) > q = dynamicsymbols ( 'q' ) > q2 = dynamicsymbols ( 'q2' ) > qd = dynamicsymbols ( 'q', 1 ) > q2d = dynamicsymbols ( 'q2', 1 ) > N = ReferenceFrame ( 'N' ) > B = ReferenceFrame ( 'B' ) > B.
