How to Choose the Appropriate Electric Dynamometer Test Bench If the Power Range of Your Test Piece is Wide?
Quote: When we provide turnkey solutions to customers, we often encounter such a situation where the customer is the original equipment manufacturer and the power range of the test piece to be tested is very wide, and the torque and speed will gradually change with the change of power. If a set of dynamometer test bench is used for the test, it will result in inaccurate test parameters. How to choose the appropriate dynamometer test bench? We'll give you a brief analysis below, and you can choose the right one according to your actual situation.
Modes | Advantages | Disadvantages |
One drag two mode | - Only one control system is needed (with a cost reduction of 30%-50%) - Low installation/maintenance costs |
- Control system failure affects two dynamometers |
Two separate systems | - The failure of one device does not affect the other | - Purchase/maintenance costs double |
Modes | Advantages | Disadvantages |
One drag two mode | - High synchronization accuracy (microsecond level) - Strong data consistency (timestamp error < 1ms) |
- Low flexibility for independent testing (partial resource sharing) |
Two separate systems | - Can perform unrelated tests simultaneously (such as motor + engine) | - Synchronization requires additional modules, dynamic load error may be > 1% |
Modes | Suitable scenarios | Unsuitable scenarios |
One drag two mode | - Dual-motor collaborative testing (for new energy vehicles) - Conduct comparative tests on a batch of products of the same model |
- The test subjects vary greatly/the process is completely independent |
Two separate systems | - Parallel testing of different types of equipment (such as motor + engine) - High reliability requirements (24-hour production) |
- Space is tight/Budget is limited |
Modes | Scalability | Maintenance features |
One drag two mode | - Easy to upgrade to one drag many (just add the number of dynamometers) | - Centralized maintenance (a professional team is required, downtime maintenance) |
Two separate systems | - Expansion requires the addition of the entire system (costs increase linearly) | - Distributed maintenance (each single device can be replaced independently) |
This article only summarizes the relevant suggestions based on customer cases. Please consider the specific solutions according to the actual situation of our company.
