The difference in fuel consumption of wheel loaders can be more than 30% according to different shoveling trajectories for operations, and the optimization is an important way reduce operations. existing trajectory method mainly through theoretical calculation simulation analysis, which cannot fully consider high randomness complexity process. It difficult achieve desired effect. Therefore, thi...

Keberhasilan suatu proyek dapat diukur dari dua hal, yaitu keuntungan yang didapat serta ketepatan waktu penyelesaian proyek. Hal ini untuk menyelesaikan dengan tepat maka salah satu harus diperhatikan adalah pemilihan alat berat. Pada penelitian dilakukan mengetahui produktivitas berat, biaya dan dibutuhkan pekerjaan lapis pondasi agregat kelas A digunakan metode Bina Marga Tahun 2018. Hasil a...

The purpose of the work is import substitution traction electric drives as part project to create in Chuvash Republic a serial production family front loaders with hybrid drive.
 
 For most transport motors, operation high-torque motor mode not main operating mode, since vehicle acceleration carried out short time overcoming low-efficiency low-speed modes. A distinctive feature for ch...

Insertion resistance is the caused by a pile to wheel loader when latter inserts into pile. It significant clarify insertion avoid slippage, increase additional energy consumption, and protect during process. To address problem that current methods cannot accurately obtain magnitude variation trend, we propose composite model based on particle swarm optimization (PSO) algorithm long short-term ...
