DYN 8WD I-30t Dynamometer - Integrated into TT 16.0-30t-DYN TurntableDynamometer brief descriptionThe TT–DYN is especially designed not to influence EMC and EMI measurements. Therefore, the electronic components are inside a shielded, radio interference suppressing box which is placed inboard the dynamometer. All the design and manufacture of vehicle test bench is in accordance with standards below: Ambient Noise requirements according to standards of CISR12, SAE J551-5 Vehicle velocity, acceleration, load, road simulation requirements and power grids requirements according to standards of CISR12, ISO11451, ECE R10, SAE J551, GB14023, GB18387, IEC61000- 4-3, GB/T 14549. Control Unit Each active element has two micro controllers to control the frequency inverters and for the speed measurement system. The element is connected to the system controller via fiber optic links. The system controller PC is equipped with an IEEE or LAN interface for remote control with a measurement software. Safety and Emergency Functions The maximum speed is limited by inverter function controller and by the internal micro controller. The temperature on the motors and inside the electronic box is being watched. Two emergency switches are located close to the stand and in the control room. In case of an emergency, the motor power will be switched off and the motors come to a standstill. There are many features, benefits and accessories included in the standard delivery scope of maturo dynamometers. Furthermore, extra accessories are provided in order to ensure a safe, efficient and easier work for our customers. Turntable brief descriptionThe turntable TT -DYN is especially designed for flush mounted installation at intermediate levels in electromagnetic absorption chambers. The framework design allows the possibility to integrate a chassis dynamometer. Movement The rotation of the turntable can also be carried out while the chassis dynamometer is in operation. The angle is measured by a position encoder. Safety for EUT For the safety of the EUT, the turntable is equipped with an acceleration/deceleration function for start and stop ramps to avoid jerky movements Emergency switch The turntable is equipped with an integrated emergency switch, which can be connected at the turntable perimeter. Limit switches The turntable is equipped with a limit switch and positioning switch system to guarantee the exact positioning of the turntable. An “overturning” of the system is prevented by using limit switches. Power supply in the center of the turntable It is possible to integrate various types of connectors for the power supply of the EUT Software and Controller Brief DescriptionThe Maturo controller DynSoft is developed by maturo engineers based on long experience. The in-house software is able to control all maturo dynamometers and their accessories, e.g. the cooling fans, the robot and so on. It will be delivered with an industrial PC and communicate with the devices by fiber optics. Due to the fact that the controller and the software are exclusively produced, developed and constantly enhanced by maturo, software maintenance or troubleshooting in case of failing components can be done very fast, optionally with a remote service unit, for minimal downtimes. The included software contains the following functions: - Emergency stop - Start cycle / stop cycle - Speed control of the rollers - Speed control of the ventilator - Force at the rim (in Nm) - Distance gone from the start of the cycle (in km) - Cycle recording (profile) To allow the following test cycles: - Constant velocity - Velocity gradient - Simulation of uphill and downhill driving - Tractive force control - Friction force control - Positive and negative rotation control - ABS, ESP testing - Road load simulation based on the GB/T 18387 standard The software includes: - PC-Controller with keyboard, mouse and monitor - The DYN-Software is pre-installed at the PC
