Hybrid Actuation System (HAS) is an advancement in the industry that brings major changes to the system design and development. The HAS will combine the benefits of both traditional electric and hydraulic actuation systems. This includes the controllability of electromechanical actuators with the power density, longer life, and resistive force capabilities of hydraulic actuators. In general, HAS will have the look and feel of an electric actuation system and power density and fail-safe characteristics of a hydraulic actuation system.
What is a hybrid actuation system(HAS)? In hydraulics, an actuation system is a drive or transmission system that utilizes hydraulic power to facilitate mechanical operation. This mechanical motion is converted to linear, rotary, or oscillatory motion. Likewise, the hybrid actuation system is ideal for linear motion applications in mobile and industrial sectors. As stated, this will combine the benefits of both electric and hydraulic actuation systems which makes the overall design compact, efficient and suitable for high-pressure applications.
How does a Hybrid actuation system differ from traditional actuation systems? When comparing a traditional actuation system with a hybrid actuation system, the key difference lies in space requirement, energy efficiency, and installation. The following points will provide you with a clear understanding of the major differences between hybrid and traditional actuation systems.
- Traditional actuation systems were complex in size. It required hoses or tubes for connecting each unit with the other. Whereas, HAS doesn’t require hoses and tubes.
- HAS uses localized power whereas, traditional systems require centralized power. Centralized power means the system will utilize a central power unit for supplying hydraulic power to all units included.
- HAS offers valveless control. But, traditional actuation systems include pressure drop valve control.
- HAS requires less oil than the traditional actuation system.
- HAS follows plug & play installation. But, the traditional approach included sizing each unit separately.
- HAS is more energy-efficient than the traditional actuation system.
Other than these, hybrid actuation systems will offer many other benefits. One among them is the ease of maintenance. Detecting the failures of traditional actuation systems will consume more time than HAS. Because traditional systems will interconnect many units together with hoses and tubes and identifying the defective part will be complicated. But, the HAS that offers simple plug-and-play functionality can be easily replaced. Compact size, ease of installation, simplified controls, energy savings, reduced leak points, reduced oil reservoir volume, and longer life are other benefits of Hybrid actuation systems.
