Replacement of brake master cylinder spring by compliant mechanism – A topology optimization approach

The current work is effort to replace the existing spring in master cylinder of automobile by means compliant approach. Spring details of three wheeled vehicle master cylinder were obtained and then simulation of spring was done for static and overall deflection. Initial Topology of complaint mechanism was obtained throughout topology optimization on ANSYS, finished topology with optimization of dimension and design of members was gained via optimality criteria evaluation method. using the obtained design mechanisms, analysis have been done. From the above analysis, deformation curve is formed and these obtained complaint flexible mechanism is compared with novel product. Reverse engineering procedure is conceded out with design data and shape compliant component have been changed from previous one and it is optimized by ANSYS to get better compliant design. This leads a conclusion that primary spring in master cylinder be replaced with obtain compliant design.
