Counterbalance Valve with Boom Arm
Model, parameterize, test, and compare design cases for a counterbalance valve in a boom arm mechanism. A counterbalance valve allows an upstream flow from the back port to the load port through the check valve stage during cylinder rod extension, and it allows a downstream flow from the load port to the back port through the relief valve stage during cylinder rod retraction in the boom arm mechanism. Counterbalance valves help with the load holding, load actuation, speed control, and safety by controlling the piston motion of the booming cylinder. When you run the model, it generates a plot of the booming cylinder position and the forces at the A side and B side of the cylinder piston.
크레인 붐 암 테스트 벤치
이 예제에서는 Simscape™ Fluids™의 유압 모델링을 Simscape Multibody™의 6자유도 운동 및 애니메이션과 결합하는 방법을 보여줍니다. 이 예제에서는 또한 크레인 붐 암 테스트 벤치에서 카운터밸런스 밸브에 대한 설계 사례를 파라미터화하고 테스트하고 비교하는 방법을 보여줍니다. 카운터밸런스 밸브는 붐 암 메커니즘에서 실린더 로드가 연장되는 동안 체크 밸브 스테이지를 통해 후면 포트에서 부하 포트로의 업스트림 유동을 허용하고, 실린더 로드가 수축되는 동안 릴리프 밸브 스테이지를 통해 부하 포트에서 후면 포트로의 다운스트림 유동을 허용합니다. 카운터밸런스 밸브는 붐 실린더의 피스톤 운동을 제어하여 부하 유지, 부하 액추에이션, 속도 제어 및 안전에 도움이 됩니다.
Drill-Ream Actuator
An actuator that drives a machine tool working unit performing a sequence of three technological operations: coarse drilling, fine drilling, and reaming. One of three pressure-compensated flow control valves controls the actuator speed as metering out return flow from the cylinder. Directional valves that are activated by a control unit perform the selection of an appropriate flow control.

Warning: This example uses the hydraulic domain, which will be removed in a future release. Find an equivalent example model that uses the isothermal liquid domain here: Drill-Ream Actuator. To convert models to the isothermal liquid domain, use the hydraulicToIsothermalLiquid tool.
Front-Loader Actuation System
A simple actuation system that has a lift and tilt cylinder. Each cylinder is controlled by an open center, 6-way, 3-position directional valve. The valves are connected in series through their unloading branch such that the system pump unloads when both spool displacements are in neutral position. If either tilt or lift command applies, the unloading path closes.

Injection Molding Actuation System
An injection molding actuation system. The model contains a set of cartridge valves that control pumps, motors, and cylinders to execute the steps of an injection molding process.
Pressure Reducing Valve in Punching Operation
Models a hydraulic system with a direct operated, pressure reducing valve. This system helps to limit and maintain pressure in a hydraulic punching machine. Pressure reducing valves are common in hydraulic pressing, drilling, and stamping applications.
Tractor Transmission Energy Flow Chart
Model, parameterize, and test a tractor with a hydrostatic continuously variable transmission (CVT). When you run one of the plot functions, you can view plots of the tractor velocity, engine speed, transmission speed, and pump and motor energy computations.
