The demand for reliability of automobiles is extremely high. In order to satisfy that requirement, it is necessary to ensure the reliability of each and every unit and component.
Presently it is common for even the first prototype to be calculated quite well by using simulation software. However, in order to guarantee the final durability, it is necessary to perform actual load testing.
As development cycle of models increase, it is necessary to conduct tests in a short period of time.By taking advantage of new measuring and analysis technologies, as well as reliability and usability of the test system, these goals can be achieved.
As more environmentally-friendly cars are in particular demand in recent years, CO2 emission reduction, and fuel efficiency improvement are important development matters. The engine is required to have lower emission, the drive line to be low friction, the vehicle body to weigh less and to have less resistance to air.
Because these developments are accumulations of small improvements, the accuracy required for the test system is very high. Selecting high accuracy measurement instruments are not enough; mechanical precision and accuracy is extremely important for achievement.
Conventional hydraulic unit was very poor in energy efficiency, but the new hybrid actuator’s energy consumption is extremely low. By adopting a servo motor, the work required at the time of holding pressure is with only minimal rotation. Even at maximum load operation the energy efficiency is 90 %.This actuator can achieve energy savings even in the field of general industrial machinery with high realization and operating time ratio.
In addition it can be used for various applications such as fatigue testing, press fitting, injection molding and so on.
