Development of ZS125 Motorcycle Engine EFI System and Parametric Design for Intake Manifold
In recent years, China’s motorcycle industry developed rapidly, production sales volume broke through 27 million, exports volume broke through 8 million, become the world’s major powers motorcycle industry. At the same time, domestic motorcycles also keep steady growth, and have broken through 88 million. Behind such a large number, environmental pollution caused by motorcycle emissions [...]
Analysis on Strength of Flange Reducer’s Annular Gear of Heavy-duty Electrical Wheel Dump Truck
This thesis is proposed as a result of the flange reducer’annular gear of heavy-duty electrical wheel dump truck damaged after a period of work. Based on the special structure of flange reducer, introduces it’s interior fixed axis gear train, analyses the contact stress and bending stress of annular gear, emphasis on the stress of annular [...]
Study on the Loess Compaction Experiment of Impact Vibratory Roller Model
The loess is widely distributed in North and Northwest China, which is the main material of highway subgrade filling in these areas. However, loess is a special soil with the features of porosity development and collapsibility, which will let soil sink with water so that the road will be damaged. It will be greatly increased [...]
