The company attaches importanceto the cultivation of R&D personnel all the time, updates knowledge andconcept by on-the-job postgraduate continuing education, professional training,overseas investigation, technical exchange and so on to adapt to the company’scontinuous development and expansion, and has formed a realistic and pragmatic,innovative and ambitious R&D team. The company introduced one hydrauliccylinder expert from Japan for 3-year technical guidance, carries out industry-university-research activities with University of Scienceand Technology of China(USTC), University of Shanghai forScience and Technology (USST), Jilin University(JLU)and soon, and undertakes municipal, provincial and national R&D projects, and ourR&D personnel have strong development ability and ample R&D management experiences, leading in the hydraulic industry.

R&D  methods

Application of finite element analysis method

To avoid dependency on design experience, reduce design errorrate, improve product reliability, the finite element analysis method isadopted at the design phase of our products to simulate rigidity, strength,stability and modal characteristics of varied parts and the complete set ofhydraulic cylinder in working conditions close to reality so as to learn staticand dynamic features of the cylinder and to reduce cost & optimizedesign.

IPR whole-flow management in R&D process

Integrate IRP into the traditional R&D management flow; makefull use of patent and literature database to search related technologiesbefore project initiation, in R&D process and before sales so as to evadeinfringement risk, enhance product technical threshold and shorten the designperiod.

PDM product data management platform

To realize uniform management of R&D basic data, R&D team&resources and R&D flow, our company initiated the product data managementsystem (PDM) project at the end of 2014. The system was officially started inJuly 2015. Our company currently has implemented PDM management in an all-roundway. A parallel collaborative R&D environment is established in our companyby the system functions of drawings & documents management, materialmanagement, product management, flow management, project management andcollaborative office.

CDS R&D design platform

Make use of CDS oil cylinder rapid design system to realize rapiddesign and assembly; and it is favorable for realizing design parameterization,serialization and modularization of the hydraulic cylinder. This system hashydraulic cylinder rapid query module, standard parts module, sealing partsmodule, series parts module, parameterized framework module, rapid outputmodule, etc and can realize rapid call, automatic assembly, parts replacement,parameterized drive and automatic output of models.

Leverage on AMCA, FT and European R&D Center

Fully exert Holland AMCA, FT, European R&D center and otherR&D platforms to strengthen technical exchange and cooperation and improvesynergic R&D effect. Provide technical support and training; achievetechnical transfer. Establish a smooth alignment channel for new designs andprocesses for exchange of needed resources and resource sharing. Make use ofEuropean high quality resources and domestication cost advantages to realizequality assurance and cost advantage.

Rely on R&D advantages of XCMG Research Institute and state key labs

With help of XCMG Research Institute, we develop high endconstruction machinery pumps, valves and motors rapidly by cooperation andenrich product clusters of hydraulic components of our company. Meanwhile, wemake full use of the state key lab of XCMG Research Institute where multipletesting equipment for hydraulic cylinders and hydraulic valves as well asadvanced testing technical level and conditions are available to facilitatetesting of products of our company.
