Tsubaki's Specialized Technologies Enable Swift Product Development
Tsubaki's Specialized Technologies Enable Swift Product Development In product development, we use two main types of evaluation. We simulate and evaluate performance using computer-aided engineering (CAE), and we evaluate prototypes using testing machines and actual engines. That combination of tests enables us to guarantee the high-level dynamic performance and durability of our timing chain drive systems.
Evaluation Technologies
Wear Elongation Testing
Fully aware of the importance of the wear elongation characteristics of timing chains, Tsubaki uses its originally developed equipment to evaluate wear elongation by reproducing a range of conditions that can arise during actual operations, such as lubricant oil degradation and impurity intermixing.
Rotational Fatigue Testing
Like good wear elongation characteristics, rotational fatigue strength is a must-have for timing chains. Rather than conventional linear fatigue tests, Tsubaki uses rotational fatigue tests to benchmark timing chain strength, which approximate conditions in a real engine. Our tests are becoming the standard for measuring timing chain strength.
Engine Bench Testing (System Evaluation)
Tsubaki uses actual engines to evaluate the performance of timing chain drive systems. Our testing methods lead the way in the measurement of operational chain tension. Tsubaki guarantees the dynamic performance of its systems by evaluating them at the respective development phases of different engines.
Simulation and Evaluation Technologies
3D-CAD
At the design kick-off stage, we use dedicated software based on Tsubaki's accumulated know-how to design optimal chain layouts. crucial if a timing chain drive system is to function effectively. Also, three-dimensional computer-aided design (3D-CAD) enhances the accuracy and ease with which we can exchange data with automakers and analyze system compatibility.
Dynamic Analysis (CAE / Simulation and Evaluation)
By using CAE to simulate the movement of timing chain drive systems, we are able to predict such important dynamic characteristics as chain tension. Also, CAE helps reduce development
FEM (CAE / Simulation and Evaluation)
Tsubaki uses FEM (Finite Element Method) to simulate and evaluate the reliability of components by measuring stress behavior. Also, we use FEM to verify the designs of all newly developed components.
