Dear all gentlemen.

I got problems in the simulation of the dynamics belt conveyor to make it can rotate using 1 drive pulley (as the motor) and another pulley as the support pulley which follows the movement of the drive pulley (as the motor) to control the motion.

Actually, I can rotate it using another part addition (called push rib support) that placing on the surface of the belt and behind the box, however, it's not like a real system in the industry, so the velocity result is always similar even in various masses. You can refer to the attached file.

I need your suggestions or maybe some references to make the dynamic solution as in the real life. Thank you for your response.
