Predicting Depth and Path of Subsurface Crack Propagation at Gear Tooth Flank under Cyclic Contact Loading
In this paper, a two-dimensional computational model is proposed for predicting the initiation position and propagation path of subsurface crack of spur gear tooth flank. In order to simulate the contact of teeth, an equivalent model of two contacting cylinders is used. The problem is assumed to be under linear elastic fracture mechanic conditions and finite element method is used for numerical...
متن کاملAnalytical Crack Propagation Scenario for Gear Teeth and Time-Varying Gear Mesh Stiffness
In this paper an analytical crack propagation scenario is proposed which assumes that a crack propagates in the tooth root in both the crack depth direction and the tooth width direction, and which is more reasonable and realistic for non-uniform load distribution cases than the other presented scenarios. An analytical approach is used for quantifying the loss of time-varying gear mesh stiffnes...
متن کاملPerformance analysis of generated hypoid gear based on measured tooth flank form data
Article history: Received 18 February 2013 Received in revised form 19 September 2013 Accepted 22 September 2013 Available online 24 October 2013 A method for predicting and analyzing the tooth contact pattern, vibration, and strength of a generated hypoid gear is needed to achieve a low-noise design and adequate quality control. However, it is not easy to analyze the performance of a generated...
متن کاملdesign, development and evaluation of a single wheel tester
the single wheel tester is an experimental device used to measure wheel forces when studying the relation of soil and wheel in a soil bin or in the field. in the model under development, a special frame holding the test wheel is connected to a loading carriage by two pairs of vertical rails and four rollers to provide a floating connection. by applying a driving torque to the test wheel shaft, ...
متن کاملConceptual Design of Single-Acting Oleo-Pneumatic Shock Absorber in Landing Gear with Combined Method
Landing gear is a structure that is mounted under the fuselage and helps the aircraft in takeoffs and landings. The most important duty of landing gear is the control of vibration exerted on the system through the shock absorber which is a common component to all the landing gear. Considering the importance of this issue, the necessity of investigating shock absorber with features such as high ...
