Notas do Editor
- Objective:Describe the target markets for the library.Message: The DCL was created in cooperation with industry leaders doing Hardware in the Loop simulation of automatic transmissions.
- Objective:Define the benefits of the DCL.Message: The DCL makes it easier and faster to create custom, high fidelity models that run in real-time.Faster and easier modeling compared to other platformsNo worrying about torque/speed directions and load flowMuch easier, and significantly faster, to produce models of any complex transmission configuration from prebuilt componentsEasy to model power losses in the transmissionMaximize fuel efficiency (very difficult to do with other modeling software)Identify where the highest losses occur to improve the designRuns in real-timeAlready used by major transmission manufacturersDeveloped in conjunction with a lead customer – the biggest manufacturer of transmissions in the world
- Objective:Define the benefits of the DCL.Message: The combination of Maple and MapleSim provides a solution for modeling and simulation that provides many unique benefits. The intuitive model creation process allows high fidelity models to be created in an extremely short timeframe.
- Objective:Showcase additional DCL components.Message: The DCL contains all the components required to build and test your driveline models. The DCL can be easily customized to your needs, and these models can be seamlessly integrated with other automotive systems in MapleSim.
- Objective:Showcase transmission models.Message: The DCL provides several transmission models that allow you to quickly and easily conduct driveline simulations. These models are fully customizable to your needs.
- Objective:Show the potential of the DCL using a full powertrain modelMessage: The goal of this model is to determine the average fuel consumption over various standard drive cycles, such as EPA and FTP.The full powertrain model includes:EngineTorque ConverterAutomatic TransmissionWheelsBrakesRoad/Drag Forces
- Objective:Show the transmission model included in the full powertrain model from the previous slide.Message: Transmission models can be easily constructed based on gear train schematics and clutch selection tables.This transmission model is based on a gear schematic that uses three connected planetary gears to provide four gear ratios. Gear ratios are selected by engaging and disengaging clutches in a specific pattern, shown in the clutch selection table and provided in a lookup file.
- Objective:Show results from a driveline simulationMessage: Realistic data can be generated from your driveline simulations in a very short amount of time. MapleSim allows for extremely efficient and high fidelity creation of your physical systems.In this slide: The results show the behavior of the engine and vehicle during the drive test. The engine revs up until the gear number is increased. The RPMs decrease in response, then increase until the next gear is engaged. The vehicle tracks the desired speed very closely, and we can see the fuel consumption stabilize.
- Objective:Summarize the benefits of MapleSim with the Driveline Component Library.Message: The Driveline Component Library is uniquely suited to bring unmatched levels of speed, fidelity, and customization in solving your modeling problems.
- Objective:Explain our consulting and support options.Message: We maintain contact throughout the MapleSim adoption process to ensure success with our product.We work together to solve problems:Our Applications Engineers consult with your team to identify areas where we can bring a unique benefitWe help you deliver your solution through software, training, and model development services to maximize your investment We continue to support your application development after your initial purchase to ensure the success of your projects with MapleSim
