XZ Brushless Linear Motor Positioning Stage
linear motors, guided by precision recirculating linear ball bearing blocks and rails. Each axis incorporates 1 micron resolution linear encoders. Dual shock absorbing dampers are incorporated into the stage to protect the stage and payload in the event of power failure. The dual axis system can also be supplied with fully integrated electronics to operate the stage under synchronized dual axis motion control. Brushless linear motor driven positioning stage gantries are ideal for applications... (read more)

Whole lot of shakin' goin' on
, there is relative motion when the frequency of a noise source coincides with a mechanical resonance. The amount of relative motion depends on the input noise level and the mechanical gain or amplification at resonance. The mechanical structure can be modeled as a second-order, mass-damper-spring
Spend Your Time Engineering, Not on Differential Equations
with something as simple as a spring-mass-damper system, for example, users must draw the free body diagram and then generate the governing equations between the physical components. Next, users must derive the differential equations for the system, convert them to integral form, and, finally, break
Making Mechanisms Move
in the program itself or imported via .dxf files. Models have physical properties that include mass, static and kinetic friction, elasticity, moment of inertia, and electrostatic charge. Available constraints in PC-based programs include pulleys, joints, dampers, ropes, inflexible rods, springs, actuators
