【Abstract】 Taken construction machinery as an example, present situations of modern design and testing technology as well as the objective and historical factors influencing their development are analyzed. Application trend of modern design and technology on construction machinery and core factors are discussed in the article. The development in the applications of optimal design, finite element method, mechanical--electric--hydraulic integration technique, parallel engineering, modular design, computer added design(CAD) and structure fatigue, hydraulic and electronic control technology and experimental research are analyzed concretely.更多还原
