摘要

Performance and emission tests have to be carried out on range of engines having wide applications and varied specifications. In this context situation compels to adopt critical measures and revamp the methodologies in the area of design and development/matching of cardon shafts, rubber couplings and development of test bed systems for testing of single/two-cylinder engines. Considering this need, a new strategic design approach has been formulated, which have reduced cost, loss of time and serious damages. This paper outlines a modern and practical approach used along with in-house available tools for controlling various dynamic behavioral issues involved. Redesign of shafts and couplings is done based on the comprehensive mass elastic data obtained from variety of engines. Apart from conventional torsional and bending vibration theories, FE and experimental tools are used to understand the modal behavior of engine-coupled systems. Case studies are elaborated with experimental findings. A typical test bed design requirements for testing of single- and two-cylinder engines, where major failures of cardon shafts are mainly due to unbalance reciprocating inertia forces, are presented along with practical evaluation of transmissibility of engine mounts and test bed.
