The floor-mounted, self-standing, low vibration test structure is provided with integrated controls. The test performs Torque Switch trip cycles, Limit switch trip cycles, and Normal Run Cycles for specified cycle durations. After starting the test, actuator is started automatically to verify the position controller functionality. The stand below is designed with dual testing stations that allow increased accuracy over a wider testing range. The test is repeated three times to get the average value. Position control is possible through the addition of a linear sensor while force control is possible through use of a strain gauge.
Shape Memory Alloys Shape memory alloys are materials that can respond to temperature changes by changing shape. The sequence is repeated until the torque switch is properly set for both directions. Torque Switch Setting: This test helps proper setting and calibration of the torque switch provided on the test actuators. Due to the inherent lack of moving parts the actuator requires very little maintenance and produces very little noise. Bundled Wire technology not only gives the Kinitics actuators a high strength-to-size ratio but also retains a high wire surface area. Stall Torque Test: In this test, the loading of the test actuator is increased for a selected direction of rotation till stall condition. Position Feedback: This test is useful for calibrating the position feedback signal corresponding to the set turns.
Test stand is capable of driving screw jacks at a constant rate for each load condition with measured input torques ranging from zero to full load. . On starting the test, the cold resistance of the motor is first recorded and the actuator is started. In wire form the wires will contract when heated and stretch when cooled. The Kinitics Linear Actuator can be easily configured to supply a pushing or pulling force. A force ranging from zero to a maximum of 30,000 lbs. The fully automated system commands flow-press temperature and test conditions such as cycle proof dynamic and static test conditions all transducers, flowmeters , servo valves, press control valves can be self-tested and calibrated without removing components from the system, the stand is rated for F-18 C + D and E + F primary and secondary actuators, nose gear flaps, actuators for F18 C + D Aircraft.
To conduct this test, define the value of set turns and the number of open-close operations. The test ends with the verification of the position feedback signal. Three power sources drive the actuators in various directions, and the stands come equipped with instrumentation to measure actuator speed, load, current, and voltage. One side is high speed up to 4,000 rpm and the other side is high torque up to 5,000 in-lb. Cyclic Load: This test is performed for endurance study of the test actuator.
Phase Sequence Test: The test is conducted to check and correct the direction of rotation of valve actuator with respect to the incoming supply phase sequence. The torque switch is to be manually adjusted until it trips. These two options would then be used in the configurator below to generate the actuator part number. Dynaspede designs a variety of custom-built automated, computerized test rigs for endurance study on servo-hydraulic and electro-mechanical actuators and actuator motors. Actuator travel, or stroke, depends on the travel modifier incorporated into the actuator, which in turn impacts the allowable operating force.
The pre-set loads are applied for the set durations with the monitoring and recording of the hot resistance of the winding at specified durations. The actuator is automatically started with the load corresponding to set the torque. Test rigs for performance study and Routine Testing of Industrial Electric Rotary Actuators The Dynaspede Test Rig for Electric Rotary Actuators is designed to validate the performance of rotary valve actuators in process industry applications. Emprise custom designs each test stand to meet our client's specific testing needs. Limit Switch Setting: The test allows proper setting of the limit switches provided on the actuators for setting the maximum rotational limit. Temperature rise test: The test is performed to monitor and record the motor winding temperature rise when run under predefined cyclic loads. This allows for forward stroke times below 200ms and sub-five second cycle times.
Additionally, various parameters such as voltage, current, temperatures are logged for each lift, and this data can be analyzed to detect long-term characteristics in the actuator or controller. The system builds on existing gearbox design, adding a sleek, simple rider interface to provide push-button semi-automatic or fully automatic shifting. The recorded values are used to determine the temperature rise in the motor. It facilitates Automatic sequencing of various tests according to a prescribed program, allows instantaneous display of performance parameters, and stores the results as tables, graphs and trends. If the direction of rotation is incorrect, the incoming phase sequence is changed, by clicking t he sequence button on the computer, until the direction of rotation actuator is corrected, when tested for both directions.
Emprise Actuator Test Stands are designed to test aircraft actuators such as flap actuators and cargo door openers. Once the actuator is stalled, loading is decreased till the motor starts running again with the recording of the pull up torque and current values. . . . .
