풀리 네트워크를 사용한 동력 전달
R2026bSimscape Driveline Couplings and Drives 라이브러리에는 동력을 전달하는 데 사용할 수 있는 풀리 블록이 포함되어 있습니다. Belt Pulley 블록은 단순한 벨트 구동식 마찰 풀리를 나타냅니다. Belt Drive 블록은 두 개의 Belt Pulley 블록을 결합한 것으로, 개방형 벨트 시스템(open belt system) 또는 교차형 벨트 시스템(crossed belt system)으로 구성할 수 있습니다. Belt Pulley를 사용하면 단순한 호이스트를 모델링할 수 있습니다. 더 복잡한 메커니즘을 모델링하려면, 여러 개의 풀리 블록을 장력 장치와 결합해야 하며, 장력 장치는 스프링과 댐퍼를 사용하여 구성합니다. 다른 Simscape 블록과 Simscape Driveline 블록을 포함시켜서 고충실도 모델을 빌드할 수 있습니다.

Tensioner with Custom Belt Pulley Components
Model a belt drive with a tensioner by using a custom pulley domain. The custom domain accounts for the two-dimensional kinematics and dynamics of the system. The belt drive contains an input pulley, output pulley, and tensioner, arranged in a two-dimensional space. The input pulley receives a torque from the shaft, and the belt transfers the power to the output pulley. The tensioner has a spring-damper unit that maintains tension in the system.
CVT with Custom Belt Pulley Components
Use a custom belt pulley library to build a pulley-based continuously variable transmission (CVT). The CVT comprises two variable-radius pulleys connected by a closed-loop belt. The custom domain accounts for changes in pulley radius and the effects on belt tension and belt mass distribution. The input pulley increases its radius with speed via centrifugal force, while the output pulley adjusts its radius based on belt tension and a spring. An external source applies torque to the input pulley, and the belt transmits power to the output pulley. The distance between the input and output pulleys is 200 mm, and the radius of each pulley can vary from 22 mm to 43 mm.
Elevator with Custom Belt Pulley Components
Couple custom belt pulley blocks with position-based mechanical translational blocks to build an elevator system. The elevator is a belt drive system with a car and a counterweight. The drive pulley and return pulley are at the top and bottom, respectively, and the car follows the guide rails. The distance between the drive pulley and the return pulley is 20 m, and the radius of each pulley is 0.5 m.
