The block is designed to simulate an ideal constant gear (speed) ratio between two translatory moving bodies. The block is described by the following formulas:
where:
- sC and sR – positions of bodies at ports "C" and "R", respectively, m
- vC and vR – speeds at ports "C" and "R", respectively, m/s
- aC and aR – accelerations at ports "C" and "R", respectively, m/s2
- FC and FR – forces at ports "C" and "R", respectively, N
- U – gear (speed) ratio
To simulate the motion of the bodies in different directions, a negative ratio should be set.
The block allows you to change the direction of the "C" and "R" ports for easy connection to other blocks of the model. If the block has both input ports, then the coupling equation is solved. A detailed description of the simulation approach for the gear (speed) ratios is given on the page Simulating transmission.
The gear (speed) ratio value U is displayed next to the block.
