Force sensor in mechanical translational systems
Simscape / Foundation Library / Mechanical / Mechanical Sensors
The Ideal Force Sensor block represents a device that converts a variable passing through the sensor into a control signal proportional to the force. The sensor is ideal since it does not account for inertia, friction, delays, energy consumption, and so on.
Connections R and C are mechanical translational conserving ports. Connect this sensor in series with the block where you want to measure the force because force is a Through variable (for the mechanical translational domain). The sensor constrains ports R and C to allow no motion between them, therefore connecting the sensor in parallel may affect the simulation results because it is analogous to adding a bypass connection line between the connection points. A series connection within an existing line does not affect the simulation results and provides an accurate measurement.
Connection F is a physical signal port that outputs the measurement result. The block positive direction is from port R to port C. This means that positive force applied to port R (the sensor positive probe) generates a positive output signal.
F— Force, N
Physical signal output port for force.
R— Rod (positive probe)
Mechanical translational conserving port associated with the sensor positive probe.
C— Case (reference probe)
Mechanical translational conserving port associated with the sensor negative (reference) probe.
