Abstract:

The cam disk plays a critical role in converting rotational motion into reciprocating motion in high-pressure fuel pumps, directly influencing fuel delivery accuracy, mechanical efficiency, and component durability. However, under high-speed and high-load conditions, the cam–plunger contact pair is subjected to complex stress, vibration, and wear phenomena that significantly affect system stability and lifespan.

In this study, a comprehensive design optimization and dynamic analysis of the cam disk mechanism is conducted using both finite element analysis (FEA) and multi-body dynamics simulation. The geometric parameters of the cam profile—such as lift curve shape, pressure angle, and base circle radius—are parametrically modeled, and their effects on plunger motion characteristics and contact stress distribution are investigated.

A multi-objective optimization framework is established to balance fuel delivery uniformity, contact fatigue life, and mechanical efficiency. The response surface methodology (RSM) combined with genetic algorithms (GA) is employed to identify the optimal cam contour. Results show that the optimized cam disk reduces peak contact stress by 18% and improves volumetric efficiency by 6.5% compared with the baseline design.

Furthermore, an experimental validation using a high-speed cam–plunger test bench confirms the accuracy of the simulation results. The dynamic pressure measurement and vibration analysis indicate that the optimized cam disk provides smoother motion, reduced impact load, and enhanced fatigue reliability under 3000 rpm high-speed operation.

This research provides an effective methodology for the integrated design and performance enhancement of cam disk mechanisms in modern high-pressure fuel systems, offering insights for improving energy efficiency and mechanical durability in next-generation diesel and gasoline injection pumps.
