Abstract:

In order to solve problems modular type camshafts have, that is, reducing weight, increasing oil filling time and designing multi-valve system, research was initiated about feasibility for DfE (Desing for Environmrnt) about ultralight camshaft . Through LCA (Life Cycle Assessment) and properties and process evaluation, an attempt has been made to develop cost-effectvie process for ultiralight aluminum camshaft without the problems modular type camshaft have. The results clearly show 50% weight reduction achieved and better environmental impact of the ultralight aluminum camshaft compared with

Abstract:

This paper presents the structure and static model of engine camshaft analysis. For the purposes of this analysis, the finite element method is used. Camshaft is one of the critical components for effective and precise work of internal combustion engines. This camshaft rotates at high speed causing pressure and vibration in the system. Camshafts are also subject to varying fatigue burden due to cam plunger contact. These precise values are required to be determined to prevent failure in the camshaft. The objective of the project is to model and to perform pressure analysis on the camshaft mach

Abstract:

Camshafts play a critical role in internal combustion engines, dictating the timing and duration of valve opening and closing events. To ensure optimal engine performance and longevity, camshaft design must balance factors such as strength, durability, and weight.

Abstract:

Induction hardening (IH) is a popular choice for automotive components such as camshafts for its ability to harden portions of a component selectively. The camshaft will contact the tappet, connected to the rocker arm, to open and close the valve whenever the engine is running. This contact between the camshaft and the tappet causes wear on the camshaft surface. IH of the camshaft is required to improve wear resistance and service life, as well as core elasticity to absorb high torsional stresses. It is known that studies about IH on camshafts are still very limited. This study aims to determi

Traditionally, cam-follower systems are designed by assuming a constant camshaft speed.

Abstract:

Abstract Camshaft plays an important role in the internal combustion engine, where it regulates the opening and closing time of the valves to allow fuel and air mixture to enter the engine and exhaust. The study aims to analyze the fatigue characteristics of the camshaft made from gray cast iron and cast carbon steel. SolidWorks and ANSYS Workbench were used to design and predict the lifespan of the camshaft. The modelled camshaft was used to analyze the fatigue properties. Modal analysis was performed to evaluate the deflections and natural frequency of the camshaft while static structural an

Abstract:

Camshaft is one of the key components of vehicle engines. In this paper, an independent optimization and simulation module for camshaft grinding was developed. First an optimization algorithm based on the least square method was proposed according to the constant linear velocity mathematical model of the camshaft. The algorithm can be used to smooth speed curves and improve machining efficiency and accuracy. Then the real time dynamic simulation of the camshaft grinding process was finished to perform the machining status according to the optimized motion path of the process system components.

Abstract:

A valve mechanism supports the working process of an engine cylinder, and a camshaft is a key component required to open and close a valve. When a camshaft loosens, the balance of the engine disrupts. In the meanwhile, the generalised force at its centre of gravity (CG) alters. This study proposed a novel technique to detect camshaft loosening based on recognising the generalised force at the CG of the engine. We conducted Hanning windowed interpolation of discrete spectra to extract the precise phase and amplitude by utilising the acceleration signals at the engine cylinder and mounts and cyl
