Pleas try below code.

$product_id = 'your bundle product id';

$_objectManager = \Magento\Framework\App\ObjectManager::getInstance();

        $store_id = 1;
        $options = $_objectManager->create('Magento\Bundle\Model\Option')
            ->getResourceCollection()
            ->setProductIdFilter($product_id)
            ->setPositionOrder();
        $options->joinValues($store_id);
        $typeInstance = $_objectManager->get('Magento\Bundle\Model\Product\Type');
        $selections = $typeInstance->getSelectionsCollection($typeInstance->getOptionsIds($product), $product);
        foreach($selections as $selection){
            if($product->getSku() == $selection->getSku()){
                return $selection->getSelectionQty();
            }
        }
        print_r($selections);

<ul>
<?php

$productId = 17; //any bundle product id
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$product = $objectManager->get('Magento\Catalog\Model\Product')->load($productId);
        //get all the selection products used in bundle product.
        $selectionCollection = $product->getTypeInstance(true)
        ->getSelectionsCollection(
            $product->getTypeInstance(true)->getOptionsIds($product),
            $product
        );

    foreach ($selectionCollection as $proselection) {
                $selectionArray = [];
              echo  '<li>'; 
               echo $selectionArray['selection_product_name'] = $proselection->getName();
               echo '<br>';

               echo $selectionArray['selection_product_price'] = $proselection->getSelectionQty();
                 echo '</li>';
            }
