Most of the heavy earth moving machineries used in these industries are mobile with engine as the main source of power. The work deals with two different hydraulic circuits: first the proposed one and second the conventional one, and both are studied at laboratory scale, which resembles the circuit of the hydraulic excavator. In the hydraulic circuit, out of the three hydraulic linear actuators, two are connected with hydro-pneumatic accumulators and one hydro-motor is also taken into consideration, which resembles the boom, arm, bucket and swing motor, respectively. The idea behind the proposed circuit is to store substantial potential energy during downward movement of the two linear actuators in the accumulators, which resembles the boom and arm cylinder of the excavator. The stored energy is used for upward motion of the two actuators without utilizing any energy from the main pump. For the devised strategy, MATLAB\/Simulink environment has been utilized for developing the simulation model and the same has been validated with the experimental data with reasonable accuracy. The effect of accumulator volume and pre-charge pressure has been studied for optimization of the accumulator size on the validated simulation model. This concept helps in saving 14.06% energy than its conventional counterpart which does not have the energy storage elements. The linear position control of the boom and the arm actuator in the proposed circuit have been accomplished using proportional\u2013integral\u2013derivative control and pressure-compensated proportional flow control valve and have been achieved with reasonably accuracy.<\/jats:p>","DOI":"10.1177\/0959651820904274","type":"journal-article","created":{"date-parts":[[2020,3,10]],"date-time":"2020-03-10T08:01:27Z","timestamp":1583827287000},"page":"1133-1149","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":4,"title":["Performance enhancement of hybrid hydraulic excavator using multiple hydro-pneumatic accumulators"],"prefix":"10.1177","volume":"234","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3097-0254","authenticated-orcid":false,"given":"Prabhat","family":"Ranjan","sequence":"first","affiliation":[{"name":"Department of Mining Machinery Engineering, Indian Institute of Technology (ISM) Dhanbad, Dhanbad, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mohit","family":"Bhola","sequence":"additional","affiliation":[{"name":"Department of Mining Machinery Engineering, Indian Institute of Technology (ISM) Dhanbad, Dhanbad, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3426-3066","authenticated-orcid":false,"given":"Gyan","family":"Wrat","sequence":"additional","affiliation":[{"name":"Department of Mining Machinery Engineering, Indian Institute of Technology (ISM) Dhanbad, Dhanbad, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9173-5894","authenticated-orcid":false,"given":"Santosh Kr.","family":"Mishra","sequence":"additional","affiliation":[{"name":"Department of Mining Machinery Engineering, Indian Institute of Technology (ISM) Dhanbad, Dhanbad, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jayanta","family":"Das","sequence":"additional","affiliation":[{"name":"Department of Mining Machinery Engineering, Indian Institute of Technology (ISM) Dhanbad, Dhanbad, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2020,3,10]]},"reference":[{"key":"bibr1-0959651820904274","first-page":"39","volume":"27","author":"Kagoshima M","year":"2007","journal-title":"Kobelco Technol Rev"},{"key":"bibr2-0959651820904274","doi-asserted-by":"publisher","DOI":"10.3390\/en9121002"},{"key":"bibr3-0959651820904274","doi-asserted-by":"publisher","DOI":"10.1016\/j.autcon.2016.03.016"},{"key":"bibr4-0959651820904274","unstructured":"Breen J.
