使用带轮网络进行动力传输
R2026bSimscape Driveline Couplings and Drives 库中包含带轮模块，可用于传输动力。Belt Pulley 模块表示一个简单的皮带驱动摩擦带轮。Belt Drive 模块组合了两个 Belt Pulley 模块，您可以将这两个模块配置为开口带或交叉带系统。您可以使用 Belt Pulley 来对一个简单的起重机进行建模。要对更复杂的机构进行建模，可以将多个带轮模块与张紧器组合在一起，其中的张紧器使用弹簧和阻尼器进行构建。通过添加其他 Simscape 和 Simscape Driveline 模块，可构建高保真模型。

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.
