Abstract
In high-speed gear drive and power transmission, system impact failure mode always occurs due to the sudden impact and shock loading during the system in running. Therefore, study on the amount of impact energy that can be absorbed by a gear is vital. Impact test equipment has been designed and modelled for the purpose to study the impact energy on gear tooth. This paper mainly focused on Finite Element Analysis (FEA) of impact energy that occurred during simulation involving the impact test equipment modelling. The simulation was conducted using Abaqus software on critical parts of the test equipment to simulate the impact event and generate impact data for analysis. The load cell in the model was assumed to be free fall at a certain height which gives impact load to the test gear. Three different type of material for the test gear were set up in this simulation. Results from the simulation show that each material possesses different impact energy characteristic. Impact energy values increased along with the height of load drop. AISI 1040 were found to be the toughest material at 3.0m drop that could withstand up to 44.87N.m of impact energy. These data will be used to validate data in physical experiments in further study.
Highlights
Impact test commonly used to study the toughness and strength of materials
AISI 3215 show the extreme deformation in tensile while no deformation in compression area
Results from Abaqus simulations were focused on the impact energy produced from the load being dropped and effects on the displacement of gear tooth
Summary
Impact test commonly used to study the toughness and strength of materials. Syafiqah Nur Azri et al [1] had come to a conclusion, fracture often occurs at the impacted zone where compression was more dominant in high-velocity impact, differ for low- velocity impact, invisible cracks often occur but cannot be seen using the naked eyes. There was several impact test equipment that often used by researchers to investigate factors for the ability of the materials to absorb energy during deformation or fracture of material’s toughness that includes drop weight impact test, Charpy and Izod impact test [2,3,4,5]. There was some cause which referring to this impact failure. These include the improper gear assembly, poor gear set design, shock load or foreign object falls into the gearing sets Advanced developments in the finite element method (FEM) makes most researchers are more likely to perform finite element method in advance for data verification purposes [9,10,11]
