A Coupled Torsional‐Transition Nonlinear Vibration and Dynamic Model of a Two‐Stage Helical Gearbox Reducer for Electric Vehicles

open access: yesShock and Vibration, Volume 2020, Issue 1, 2020., 2020
A coupled torsional‐transition nonlinear dynamic model of a two‐stage helical gear (TSHG) reduction system for electric vehicles (EVs) is presented in this paper. The model consists of 16 degrees of freedom (DOF), which includes factors such as the nonlinearity of backlash, time‐varying mesh stiffness (TVMS), mesh damping, supporting bearings, static ...

LAKNAT BAGI PEZIARAH KUBUR (Kajian atas Hadis Ziarah Kubur Bagi Perempuan)

open access: yes, 2021
Hadis-hadis yang berkaitan dengan hukum ziarah kubur bagi perempuan, ditemukan tidaklah tunggal, dan karena ketidaktunggalannya itu, meniscayakan atau melahirkan hukum yang berbeda-beda pula. Redaksi hadis yang melaknat perempuan ziarah kubur tidak bisa serta merta distempelkan kepada seluruh perempuan yang ziarah kubur karena ada banyak hadis yang ...

A New Mathematical Modeling Method for Four‐Stage Helicopter Main Gearbox and Dynamic Response Optimization

open access: yesComplexity, Volume 2019, Issue 1, 2019., 2019
A new mathematical modeling method, namely, the finite element method and the lumped mass method (LMM‐FEM) mixed modeling, is applied to establish the overall multinode dynamic model of a four‐stage helicopter main gearbox. The design of structural parameters of the shaft is the critical link in the four‐stage gearbox; it affects the response of ...

A Coupling Dynamics Analysis Method for Two‐Stage Spur Gear under Multisource Time‐Varying Excitation

open access: yesShock and Vibration, Volume 2019, Issue 1, 2019., 2019
A new modeling method is proposed to simulate the dynamic response of a two‐stage gear transmission system using the finite element method (FEM). The continuous system is divided into four modules: shaft‐shaft element, shaft‐gear element, shaft‐bearing element, and gear‐gear element. According to the FEM, the model is built with each element assembled.
