Industry-University-Research Cooperation has reached a new level

Popwil joined together with The College of Information science and Electronic Engineering of Zhejiang University to invest six million to build a new public experimental platform, named Interdisciplinary Motion Dynamics Simulation Platform, and focused on R&D in the area of Multi-degree-of-freedom seismic and space attitude simulation and control.
The new laboratory is located in the beautiful Haining campus of Zhejiang University, and has floor area of 500 square meters. The laboratory will build a high response 6 degrees of freedom Stewart platform based on a 5G network-based integrated data acquisition system. The platform is also equipped with silent hydraulic power system and other related equipment. The short-term goal of the laboratory is to develop a new generation of ultra-high-speed POP-M controllers with closed-loop control frequency exceeding 4 kHz with new network-based control software. The middle term goal is to do R&D on associated technology and products in civil engineering test and quality control, motor vehicle road simulating and seismic simulating platform, space or sea state motion and attitude simulating platform, and other related fields.

Popwil and Hong Kong Polytechnic University further in-depth cooperation

In October 2007, Hangzhou Popwil Electromechanical Control Engineering Co., Ltd. (Popwil) produced a 1,000-ton microcomputer-controlled electro-hydraulic servo large-scale multifunctional structure test system for Hong Kong Polytechnic University. For more than ten years, Popwil The company provided complete after-sales service for the system from annual maintenance to test aid design, from displacement sensor repair and replacement to hydraulic source cleaning, and assisted users to complete a series of major scientific research and test projects, which were recognized and praised by users. .

On October 9, 2019, Popwil signed a contract with the Hong Kong Polytechnic University to develop a 2500-ton large-scale structural pressure testing machine for the compression performance test of high-strength structural columns based on the space size of the structural laboratory of the Hong Kong Polytechnic University. The maximum vertical test pressure of the machine is 25000kN. The computer electro-hydraulic servo control system automatically controls the loading process. The test data can be output to the data acquisition system in digital or analog type. External dimensions of the test machine: 4920 × 3400 × 2345, the maximum test space: 2000 × 1800 × 1500mm. The design scheme of the aircraft is as follows:

The signing of the contract indicates that the users of Hong Kong Polytechnic University not only recognized the quality of Popwil products, but also affirmed the professional services of Popwil. We will, as always, work hard to provide Hong Kong Polytechnic University and other users with a series of services from testing equipment consulting, laboratory construction planning to testing equipment research and development, testing aid design and production, and testing equipment maintenance and upgrading to achieve a win-win cooperation. purpose.

Offshore Wind Power Operation and Maintenance Equipment – Heavy Duty Six Degrees of Freedom Swing Platform

After the dual six DOF platform designed and manufactured by Popwil was officially accepted by the Ocean College of Zhejiang University in September 2019, Popwil has signed a new joined research and development contract with a marine engineering company to design and manufacture a heavy duty six degree of freedom sea state simulating platform.
The heavy-duty 6-DOF swing platform is designed to testing other 6-DOF swing platforms which will be installed on the offshore wind power operation and maintenance ships which can work under 5 grade sea situation. After test, qualified platform will be installed on the ship to balance the affection of the sea wave and build a bridge from the ship to the offshore wind power tower or other offshore platform. The function of the bridge is to transfer people and goods with a six-degree-of-freedom wave compensation function. It is widely used in offshore wind power, offshore oil prospecting and military-civilian integration docking and rescue operations.

Zhejiang University “Dual Six Degrees of Freedom Simulation Platform”

After nearly half a year of hard work, the installation and commissioning of the dual six-degree-of-freedom simulation platform developed by Popwil for the Ocean University of Zhejiang University was completed and successfully passed the acceptance of the expert group. The application test research in the sea state environment provides the guarantee on the equipment.

The equipment is introduced as follows:

The dual six-degrees-of-freedom simulation platform consists of a large six-degrees-of-freedom simulation platform installed on the foundation of a civil construction sinkhole, a small six-degrees-of-freedom simulation platform installed on the ground foundation, and a training and training platform for the above two professional platforms. The six-degree-of-freedom teaching and training platform used for teaching, preview of large-scale projects, and model tests is composed of three devices. Among them, the small six-degree-of-freedom simulation platform and the six-degree-of-freedom training platform share a POP-NI 6-channel controller. The simulation platform is independently equipped with a POP-NI type 6-channel controller. The three platform systems share a set of electro-hydraulic servo oil source with a rated flow of 1000L / min. It has a video monitoring and alarm system and is mainly used for ships and marine equipment. Application test research under simulated sea state environment.
