注目の例
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.
Crane Boom Arm Test Bench
Combine hydraulics modeling in Simscape™ Fluids™ with six-degree-of-freedom motion and animation in Simscape Multibody™. This example also shows how to parameterize, test, and compare design cases for a counterbalance valve in a crane boom arm test bench. 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. A counterbalance valve help with the load holding, load actuation, speed control, and safety by controlling the piston motion of the boom cylinder.
ドリルリーマ アクチュエータ
この例では、荒加工、微細穴加工、リーマ加工という 3 つの一連の技術的操作を実行する工作機械の作業ユニットを駆動するアクチュエータを示します。アクチュエータの速度は、シリンダーからの戻り流量を排出側で調整する 3 つの圧力補償流量制御バルブのいずれかで制御されます。適切な流量制御の選択は、制御ユニットで有効化される方向制御バルブによって行われます。
Drill-Ream Actuator
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: ドリルリーマ アクチュエータ. To convert models to the isothermal liquid domain, use the hydraulicToIsothermalLiquid tool.
フロントローダー作動システム
この例では、リフト シリンダーとティルト シリンダーで構成される簡略化したバージョンの作動システムを示します。各シリンダーは、オープン センター型の 6 方向 3 位置方向制御バルブによって制御されます。バルブは、両方のコマンド レバーが中立位置にあるときにシステムのポンプが無負荷になるように、無負荷側の分岐に直列に接続されます。ティルト コマンドまたはリフト コマンドのいずれかが適用されると、無負荷経路は閉じます。
Front-Loader Actuation System
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: フロントローダー作動システム. To convert models to the isothermal liquid domain, use the hydraulicToIsothermalLiquid tool.
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.
